How to set up Arduino IoT Cloud Dashboard. Create an account and add things in Arduino IoT Cloud.In the Arduino Cloud tutorial video, I have covered the following steps in detail. Tutorial video on Arduino IoT Cloud ESP8266 Required Components for the NodeMCU projects I have used a 5V 2Amp mobile charger to supply the circuit. I have used the INPUT_PULLUP function in Arduino IDE instead of using the pull-up resistors with each switch.Īs per the source code, when the control pins of the relay module receive the LOW signal the respective relay will turn on and the relay will turn off for the HIGH signal in the control pin. The circuit is very simple, I have used D1, D2, D5 & D6 GPIO pins to control the 4-channel relay module.Īnd the GPIO SD3, D3, D7 & RX connected with the pushbuttons to control the relay module manually.
