-Pairing with any Arduino/Raspberry Pi Bluetooth accessory -Control a 4 relay module ( Can be upgrade to controle a 16 relay module ). -Test and controle all the ralay module function at once.

LoRa-Project-with-ESP8266-Arduino-control-Relay In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So after ...

In this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are not using any Relay Driver IC like ULN2003 and will only use an NPN transistor to control ...

Relay Driver Circuit Explanation: In this 4-Channel Relay Driver Circuit we have used an optocoupler whic his triggered by active LOW signal, to trigger the NPN transistor which further drives the ...

The 4 Relay Module is another critical component, allowing Twinky to control multiple devices simultaneously.
