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 ...

Connect the GND of the battery to the GND of arduino – common GND. If you are using a 5V relay instead of 12V relay, you only have to connect the arduino GND. I am using a 12V relay. So the coil ...

An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.

Because students are using it, it needs to be short-circuit-proof – no possibility that a mix-up in control signals can cause the drive to short out the rails (see DANGER, right). BTW, don’t use these ...

I use these all the time in my designs, for AC and DC control and HV (up to 5KV) by connecting in series. You have to understand the limitations like switching time, isolation and on resistance ...

Motor controller programmes through Arduino IDE ClearCore CLCR-4-13 is an industrial IO and motion controller that can be programmed using the Arduino IDE. It handles up to four axes of ...
