It goes without saying nothing forbids to replace the LED with a relay in order to drive loads the most important. But let’s see in detail the circuit: The operation is quite trivial: by touching the two contacts of the sensor “SENS” with hands for example, the weak current flowing ...
Arduino IR Remote Control Relay Module Description: In this Arduino project, we will make a circuit that can control room light, fan from IR remote. Here ... Read More Auto Stop Water Tap using Arduino and HCSR04 Description: In this arduino-project, I have made an auto stop water tap ...
Also, RTDS gives the circuit breaker status to the relay. The relay detects the fault and sends the trip command to the circuit breaker. As soon as the relay initiates the reclosing cycle, it informs the Arduino board to start processing, specifically to start the classification of permanent ...
Arduino Digital Clock using DS3231 Pi Module circuit diagram So, connect the SDA or D pin of your RTC module to the SDA pin and the SCL or C pin to the SCL pin of your Arduino board. The Vcc pin of the RTC module can be connected to either +5V or +3.3V of your Arduino and th...
