The switching contacts of a relay are completely isolated from the coil, and hence from the Arduino. Measure Pitch Roll and Yaw Angles Using MPU6050 and Arduino. When LDR senses light intensity above 500 than the connection between COM and NO pin is broked and the light … Circuit of the Arduino Control Relay Complete circuit of the Arduino Control Relay Module. Arduino is an open-source electronics platform that combines both open source software and hardware to let people make interactive projects with ease. It only receives the characters sent from ESP-01 modules through its UART terminals and compares it to send the turn ON/OFF signal to the Relay. * A relay basically allows a relatively low voltage to easily control higher power circuits. The code will cycle this every 3 seconds. The Complete program for Arduino is shown below: The further detail about 2 relay module interfacing with Arduino will be given later in this tutorial. By wiring these outlets to the relays we created a plug-and-play device that works on both ends. Guide for Interfacing Relay with Arduino.
