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,

This topic shows how to build a real time clock with temperature monitor using Arduino, DS3231 RTC and ST7735R (ST7735S) 1.8″ color TFT display. Building this project with Arduino is so easy, in the circuit there are two pushbuttons to
This post shows how to simulate the Arduino and the ST7735R (ST7735S) 1.8″ SPI TFT display. To do this we need a Proteus version with the ST7735R library (model), new versions (for example 8.6 and higher) have this library, old
As a simple addition to the Arduino real time clock with alarms and temperature monitor project, I’m going to add an IR remote control function to the circuit. The remote control used in this project is a TV one (LG
