Story

Imagine coming home after a long day at work, and with a simple tap on your smartphone, you can illuminate your living room with the perfect lighting. This is the vision behind our Smart Home Automation (Lamp) project. We aim to create a convenient and energy-efficient way to control the lighting in your home, making your life more comfortable and sustainable.

Instructions:

1) Set up your Bolt WiFi module and connect it to your WiFi network following the manufacturer's instructions.

2) Connect the relay module to the Bolt module using jumper wires:

Connect the VCC of the relay module to the 5V pin of the Bolt module.
Connect the GND of the relay module to the GND pin of the Bolt module.
Connect the IN1 (or equivalent) pin of the relay module to any GPIO pin on the Bolt module (e.g., GPIO0).

3) Connect your appliance (e.g., a lamp) to the relay module. The appliance should be connected to the COM and NO (normally open) terminals of the relay.

4) Write Python code to control the relay module.
