Last time I made a simple half-wave controlled rectifier using Arduino and thyristor (SCR), and in this topic shows how did I built a full-wave bridge rectifier using Arduino (half-controlled bridge rectifier). Previous project link is the one below: SCR
This small topic shows how to build a simple single-phase half-wave controlled rectifier using an Arduino board and an SCR (Silicon Controlled Rectifier) or let’s say thyristor. The SCR (thyristor) is a three-terminal device (Anode, Cathode and Gate) with four

This topic shows how to get started with Arduino and SD card (microSD cards). It shows how to read information about SD card connected to the Arduino board. The example reports volume type, free space and other information using the
In this tutorial I’m going to control a DC motor speed and direction of rotation using Arduino uno board, rotary encoder and L293D motor driver chip. I used the rotary encoder shown below: The rotary encoder has 5 pins: GND,
