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 6V or 12V relay, one 1N4007 diode and a 12V fan ...

In this Arduino Relay Control Circuit we have used Arduino to control the relay via a BC547 transistor. We have connected transistor base to Arduino pin A0 through a 1k resistor. An AC bulb is used ...

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 ...

Resistance of relay coil is measured using a multimeter which turn out to be = 400 ohms. Vin pin of Arduino gives = 12v. So current need to turn on the relay = 12/400 Amps = 30 mA . If both relays are ...

This weeks Tech Tuesday shows you how to drive model railway point motors with the Arduino microcontroller platform. In this video we show you how to program the Arduino to control a 16-channel 12V DC ...

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 ...

Arduino Due and the Ethernet shield W5100 have the microcontroller, which has enough GPIO pins for the 16 channel relay , or 2x 8-channel relay. Since Due does not have everyone, the prepared source ...

It uses a 12V, 1A voltage regulator to provide 12V DC regulated power supply to the Arduino Nano board, relays (RL1-RL4), and optocouplers (IC1-IC4). Multi-house Water Pump Control System -Working The ...
