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 ...

The relay board has a built-in error that must be found and fixed before use, turning learning into a real task with ...

Planning another Arduino build? If you’re just doing something simple like switching a relay or powering a LED, you might want to think about the Digispark. It’s a very small ATtiny-bas… ...

The 4 channel smart relay board is powered by a ESP32 WROOM providing the ability to safely control up to four appliances or devices on a load of 110-250 VAC/7A, 30 VDC/10A depending on your needs.

To learn more about the CANADUINO MEGA 2560 Arduino development board project play the promotional ... 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

[SaltyPuglord] needed a solid state relay for a project. We’d have just bought one, but he decided to design his own in LTSpice.Along the way he made the video below, which is pretty informative ...

Use Tools>Board:>Arduino/Genuino Uno to choose the ... PIRPin defined as “2” and OutPin defined as “3”—these correspond to where you plugged the PIR sensor and power relay into the Arduino.
