Allows an Arduino board to deal with keypad 3 * 4 using one wire.

A simple circuit for measuring electrical current with Arduino.

A general tutorial on installing Arduino bootloader on ATmega8 AVR microcontroller and programming it using Arduino IDE.

CapSense touch-sensing buttons or proximity sensors for Arduino Uno, using the Cypress CapSenseMBR3 Kit

Step by step on how to program a ATtiny85 microcontroller with Arduino Uno development board.

Tutorial on communicating from the Arduino to the PC CPU and communicating from PC CPU to Arduino.

In this project, we will learn to build an IR sensor module with transistor and an Arduino as well.

A sensor that recognizes the name of the color of an object based on light sensing and a neural network that learned from previous examples.

I created a GUI for Arduino. Using the GUI and the provided Arduino code you can control (PID) and measure two values

Connect up to 10 buttons using a single interrupt.

Sketch of transistor tester project from Karl-Heinz Kübbeler, so it's much simpler to study, modify, verify and upload to an Arduino.

This library creates an 8-bit IO port for Arduino by combining any 8 Arduino pins. With this library, one can send/get direct 8-bit data.

The project is a beginner guide to interface sensors to Arduino and visualise sensor data through Processing

This project uses an ultrasonic distance sensor to create a pocket of wave interference where a small object can be levitated.

The AD7793.h library provided by Analog Devices has been adapted for using on Arduino along with the SPI library.

In this tutorial we'll try to analyze how alarm systems signals might be sniffed and cloned using a cheap Arduino and some RF modules.

In this tutorial, I will show you how to install the dark theme for your Arduino IDE for the reason of overexposure to the screen light.
