The Arduino Leonardo is a microcontroller that features an ATmega32u4 microcontroller and USB connection. It comes with 20 digital input/output pins, 12 analog inputs, and a 16MHz crystal oscillator.

This project demonstrates the implementation of three sub-systems of a microcontroller: Analog Input, Analog Output, and Data Communication. The combined program reads input from a potentiometer, ...

Arduino Calculator Project This project demonstrates a simple calculator built using Arduino as the microcontroller. It accepts user input through a 4x4 Keypad and displays the result on a 16x2 LCD.

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.

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

Powering an Arduino has a little magic to it. It wasn’t obvious to me when I first started working with them, but Arduinos have on-board regulation. Taking advantage of this allows for longer power ...
