What does this project demonstrate?
The model demonstrates wireless light control over a local Wi-Fi connection. The Android phone sends a command, the controller processes it, and the light changes state. The house and garden give this electronic function a familiar setting.
- Build and decorate a miniature house and its surroundings.
- Connect the PRAGMATIC™ Coder Starter Kit controller, configured for this home-automation project, and the project light.
- Connect an Android phone to the project’s Wi-Fi network.
- Demonstrate LED ON and LED OFF while explaining the signal path.
This guide follows the kit-based model in the photographs. Exact board terminals, supply ratings and internal circuit values must come from the reference supplied with your kit; they cannot be reliably read from these photographs.

Buy from Pragmatic-Shop.in → |
| Android phone and companion app | Send ON/OFF commands over Wi-Fi |
| Kit-specified low-voltage power source | Supply the board at its rated input voltage and correct polarity |
| Connecting wires and suitable connectors | Connect the power source and project light |
| Rigid cardboard, foam board or a suitable base sheet | Support the house, landscape and electronics |
| Model house or craft materials for making one | Represent the home being controlled |
| Paint, brushes, glue and coloured paper | Create the lawn, driveway, pond and roof details |
| Artificial trees, plants and a project label | Finish the exhibition display |
| Ruler, scissors and supervised cutting tools | Measure and assemble the model |
Power note: the photographs show a rectangular battery connected to a controller board. Do not infer the board’s voltage rating from the battery’s appearance. Use the supply specified for your exact kit. This school model should use low-voltage lighting; do not connect household mains appliances.
Step 1: Prepare and paint the base
Choose a rigid base with room for the house, controller, power source and garden. Place the parts loosely first, leaving the controller accessible for testing. Sketch a driveway leading to the house, a lawn around it, and a small decorative pond at the front.
Paint the lawn green, the driveway grey, the planting area brown and the pond blue, following the arrangement below. Let the paint dry fully before attaching electrical parts. The pond is a painted feature; no water is needed.
Step 2: Build and position the house
Use a ready-made miniature house or make one from cardboard or foam board. Mark windows and doors, assemble the walls, and add a roof. The reference model has white walls and an orange-and-blue roof.
Position the house at the back of the driveway. Plan the wire route before fixing it permanently. If the light will sit inside the house, leave access through a removable roof or rear opening.
Step 3: Mount the controller and make the connections
Disconnect the power source before wiring. Mount the PRAGMATIC™ Coder Starter Kit controller beside or behind the house on an insulating support, keeping exposed contacts clear of metal, wet paint and loose wires. Keep its connectors and power switch accessible.
- Identify the board’s marked power input and the rated supply in the kit reference.
- Connect the supplied light assembly to the designated light output, following the connector labels and polarity marks.
- Route the wires neatly along the house or base. Secure them without pulling on their connectors.
- Check for loose strands, reversed connections and accidental shorts.
- Connect the rated power source only after the wiring has been checked.
If your kit uses a separate bare LED, use the current-limiting resistor and wiring specified by the kit. Do not assume that a bare LED can be connected directly across the supply. Ask a teacher or the kit supplier to confirm any unlabelled terminals.
Functional connection guide
| From | To | Check before powering on |
|---|---|---|
| Rated low-voltage supply | Controller power input | Correct voltage, polarity and connector |
| Designated controller light output | Supplied light assembly | Correct terminals and LED polarity, where applicable |
| Android phone | Smart Home Wi-Fi network | Connect using the project’s supplied password if requested |
This is a functional guide, not a replacement for the kit circuit diagram. Use the home-automation firmware and setup specified for your PRAGMATIC™ Coder Starter Kit and this companion app. Fitting an arbitrary Wi-Fi board alone will not make it work with the app.
Step 4: Arrange the garden and finish the model
Add artificial trees and flowers around the driveway. Keep decorations clear of the controller antenna area, switches and battery access. Fix each item firmly so it will stay in place during transport.
Add a clear title such as Smart Home Automation System. The photographed display also uses a Punjabi project label. Small labels reading “Wi-Fi Controller”, “Power Supply” and “Project Light” help visitors follow your explanation.
Download the Android app
Visit the Jai Maa Tech Student Project Lab and open Smart Android App Based Home Automation System. The companion app page requires the project serial code supplied with your kit.
Open the Android App Download Page →
- Open the download page on your Android phone while you have internet access.
- Enter your own kit serial code and select Verify & Download App. Keep the code private.
- Download the APK and install it. If Android requests permission to install from your download source, allow it only for this installation and turn that permission off afterwards.
- Keep the kit instructions and Wi-Fi password available for setup.
The companion app page describes the app as free for its supported Smart Home project hardware. Use it with the PRAGMATIC™ Coder Starter Kit configured for this project. The serial-code form is the download route; an app download does not replace the physical controller kit.
Step 5: Connect your phone and test the light
- Power the model. Switch on the correctly connected controller.
- Open the app. Turn on the phone’s Wi-Fi. Use the app’s Wi-Fi settings button if available, or open the phone’s settings.
- Select Smart Home. Choose this network from the Wi-Fi list and connect. If asked for a password, use the one supplied with your project.
- Stay connected. A “no internet” message is expected on this local project network. Keep the phone connected while controlling the model.
- Return to the app and tap LED ON. Check that the project light illuminates.
- Tap LED OFF. Check that the light goes out. Repeat the sequence several times before the exhibition.
These network and button names follow the official companion-app instructions . Internet access is needed to obtain the app; the documented demonstration uses the project’s local Wi-Fi connection.
How the project works
Tap LED ON/OFF → Wi-Fi command → Controller → Project light
1. User input: you press an ON or OFF button in the Android app.
2. Wireless communication: the phone sends the command over the local Wi-Fi connection to the project controller.
3. Control action: the controller’s programmed logic interprets the command and changes its light-control output.
4. Visible result: the output circuit turns the project light on or off. The power source supplies the electrical energy; Wi-Fi carries the command.
The demonstration is an introduction to smart-home control. Sensor-triggered lighting, timers and remote internet control would require additional hardware or software; they are not demonstrated by the supplied photos or app instructions.
Testing and troubleshooting
| Problem | What to check |
|---|---|
| Smart Home network is missing | Check controller power and supply condition. Allow it to start, move the phone closer and refresh the Wi-Fi list. |
| Phone reports no internet | Stay connected to the project network and return to the app. |
| App buttons do not change the light | Confirm the phone is still connected to Smart Home. Check that the app and controller are a matching kit. |
| Light stays off | Disconnect power, then check the designated output connection, LED polarity and supplied light assembly. |
| Controller restarts or works intermittently | Check for a weak supply, loose connector or short circuit. Use the correctly rated supply. |
| Serial code is not accepted | Recheck the kit’s code for typing errors. Contact Jai Maa Tech if it still fails; do not post the code publicly. |
Record your actual test results in a project notebook: button pressed, expected light state, observed light state and whether the test passed. Test ON, OFF and reconnection after restarting the model. Do not claim a fixed operating range without measuring it.
A short explanation for exhibition visitors
“This is our Smart Home Automation model. My Android phone connects to the project’s Smart Home Wi-Fi network. When I press LED ON, the phone sends a command to the controller and the light switches on. When I press LED OFF, it switches off. The battery or power supply provides the energy, while Wi-Fi carries the command. This model helps us understand how wireless control can be used in a smart home.”
Frequently asked questions
Does the model need internet during the demonstration?
The documented setup connects the phone directly to the project’s Smart Home Wi-Fi network. Stay connected even if the phone reports no internet. Download the app beforehand.
Can I use any Android home-automation app?
Use the companion app specified for the PRAGMATIC™ Coder Starter Kit and this Smart Home project. Different apps may use different commands and will not necessarily work with the controller.
Can it control a real fan or household light?
This guide demonstrates a low-voltage project light. Household appliances need appropriately rated switching equipment, protection and qualified installation. Keep the school model at low voltage.
Is a program included in this guide?
This is a build-and-use guide for the PRAGMATIC™ Coder Starter Kit configured for this project. Source code, pin assignments and firmware-upload instructions have not been supplied here. Use the documentation for your exact controller if programming is required.
