I have used D4, D5, D6 & D7 pins to control the 4-channel relay module. As per the source code, when the control pins of the relay module receive the LOW signal the respective relay will turn on and ...

This article describes the construction of a simple Arduino RFID Access control DIY (Do It Yourself) Project using Arduino UNO and a RFID reader module (EM-18) to control an LED and a Relay. Circuit ...

Now that the relay is complete, place the top of the enclosure back on and secure it with the screws it comes with. Step 9: Using a breadboard and the Arduino Uno, build the circuit specified by the ...

In his video guide, [Ben] shows us exactly how to fit a standard solid state relay into a regular outlet box, and easily control it with an Arduino Uno.

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 ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100.

This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect one phase of ...

Here in this tutorial we will control a servo motor with ATtiny13 microcontroller using PWM technique. So before going any further we will first learn about PWM, Servo Motor and how to program ...
