This Arduino project shows how to control DC motor speed using full wave controlled rectifier. The speed of the DC motor is controlled using a potentiometer (connected to the Arduino board) by varying the value of the firing angle ‘alpha’ […]
In the last project I made a half wave controlled rectifier using Arduino UNO board and one thyristor (also called SCR). This topic shows how to build a full wave controlled bridge rectifier using Arduino uno, 2 thyristors and 2

This is another Arduino project for beginners, it shows how to control LED ON and OFF with push button where the LED changes its state whenever the pushbutton is pressed. In this project, Seeed Studio Grove LED socket kit and
Using Arduino and Seeed Studio Grove ultrasonic ranger we can easily build a distance meter. This project shows how to do that where distance value is printed (in centimeters and inches) on Grove LCD (I2C 1602 LCD display) and Arduino

This topic shows how to build a simple temperature & humidity measurement station using Arduino uno board and Seeed Studio Grove DHT11 sensor module. The values of temperature (in °C) and humidity (in %) are printed on Grove LCD (1602
This small topic shows how to interface Arduino with Seeed Studio Grove LCD display that has 16 columns and 2 rows (16×2). This display communicates with the Arduino over I2C bus which means it requires only 2 data pins. Currently,
