The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

Whenever we need to connect any AC Appliance in our embedded circuits, we use a Relay. So in this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are ...

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 turning on and off the appliances the receiver ...

By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile device. In this blog ...

Fig. 3: Control panel on Android smartphone Relay module. A relay allows you to turn on or turn off a circuit using voltage and/or current much higher than what Arduino could handle. Relay provides ...

The 2-channel relay module is connected with switch S7, this is an “OK / ENTER” switch for the radio. This S7 switch has to press each time we change the station. This 2 channel relay used in this ...

This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL. Step 1 (Connect SIM900 With Arduino) Use picture as a reference for connecting SIM900 to Arduino.

The Arduino development board has grown in popularity over the last few years and has spawned a myriad of interesting projects such as auto-lacing shoes, The EyeWriter 2.0, and the Mobile Dance ...
