433MHz Radio Light Switch Control
What’s up my friends, welcome back. This project requires 2 PCBs, one for the light switch and another PCB that will receive the radio command and turn on and off a relay (SSR in this case). The transmitter PCB has a 433MHZ crystal and a simple circuit to send data. The data is created by an ATTiny85. The receiver uses a radio module and depending on the received data, it will turn on and off a relay for 220V AC. Be careful with high voltage! So, let’s get started.
