[Damian Peckett] has implemented an Apple ] [, its 6502 processor, and a cassette port, all on an Arduino Uno. If that wasn’t enough, he also uses a PS/2 keyboard for input and outputs analog VGA.

Arduino Uno, or systems based on the ATmega328 chip has no a true analog output. The easiest way is to use one of the PWM outputs and filter the signal with a passive RC filter to obtain an analog ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

This project uses an Arduino Uno CH340G clone and a DHT11 sensor to build a compact weather station that measures temperature and humidity, calculates over ten derived environmental metrics, and ...

Surely creating them from a simple microcontroller will be impossible! Not according to [techtoys], who has created an Arduino shield that creates an HDMI output from an SPI control input.

Circuit Diagram With Explanation Let's go through the circuit setup for our home automation project step by step. This project connects various sensors and outputs to the Arduino R4 WiFi, which acts ...

The Adafruit Metro RP2350 is a Raspberry Pi RP2350 development board that closely follows the Arduino UNO form factor for compatibility with existing Arduino shields. Key features include 37 GPIOs, a ...
