RC Radio Controlled Switch with Relay
This RC Relay project enables control of large current devices using a Radio Control (RC) System. This RC switch converts hobby radio control (RC) pulses to control the on/off state of the Relay. On board LED indicates the output. The board is Arduino compatible and the example code can be modified as per user requirements. The relay ON/OFF threshold can be set as per user requirements. The Arduino sample code enables momentary ON/OFF control of the relay, but this can be modified for Latch output. The relay can handle a load up to 7A – 30V DC or 7 Amps 230AC Loads such as bulbs, LEDs, motors, fans, heaters etc. The project can be connected to an unused RC channel. It operates with 5V DC and draws 60mA current when the relay is ON. 3 Pin male header helps the user to connect the RC receiver. The project is Arduino compatible and can be programmed using Arduino IDE with the help of an onboard programming connector. The project consists of an Atmega328 microcontroller, programming/bootloader connector, relay, BC847 BJT transistor to drive the relay, freewheel diode for protection from the relay, and U2 PC817 provides isolation between the microcontroller and relay. D1 LED indicates output, D3 LED power LED. connector CN2 relay switch connection, connector CN1 5V supply input.
