In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one. Aspencore network. ... When the button is ...

If so, remember to connect the VCC pin to 5V of the Arduino board to enable the control input pins IN1 and IN2. Also note at this point that, if you want perfect galvanic-isolation, do not link ...

When everything’s plugged in, this is how your Arduino, motion sensor, and power relay should look. ... The side connector pins will go into the Arduino’s ground (GND) and 5V sockets.

Goal: Control lights and appliances using relays, sensors, and a web interface. Components Needed: Raspberry Pi 4. Arduino Uno. 4-channel relay module. PIR motion sensor. Steps: Use Arduino to handle ...
