Task scheduling is a transformative way to write maintainable code for Arduino and other AVRs. No more spaghetti code. C++ tutorial.

Did you run out of input pins, don't worry here is a solution without any shift registers.

Use the program to manage your ESP module with simple commands. This will allow you to access the Internet for any Arduino product.

This device runs a desired length and quantity of wires and cuts each length.

A quick and compact Arduino Nano setup with four DIP switches to allow for mode selection. Power is provided by CR2032 battery package.

Easily include oscilloscope and frequency counter diagnostics into your own project.

Receiving and sending the digital and analog signal through AD5669 interface with Arduino to detect the A/D pulses.

Probably the most useful Arduino project I've ever made! A automatic tester for a product I sell.

Retro Atari 65XE plus Arduino Leonardo as USB-keyboard for a modern computer. It will leave the opportunity to use this Atari in native mode.

6-channel digital sampling oscilloscope with built-in frequency counter, maximum sampling rate 47kHz.

With the coming .NET Core 3.0, cross-platform serial port is available. Let's have a try on RPi Raspbian.

A bit more accurate than __TIME__.

RT-Thread, a powerful multitasking tool optimized for Arduino. You are able to issue shell (FinSH) commands to control your hardware now!

A quick tutorial on how to interface the voice recognition module with few examples.

ATtiny85/45/25 are most inserting and useful boards, but can be difficult to code and use. So here is the development board!

I want to make a spot welder for battery packs or other stuff that cannot be soldered.

Use the IO Expander and Relay Expander with the Arduino to control up to 65,280 relays!

Application notes for Pmod LS1 and Arduino Uno. The input voltage and output level of the comparator module is displayed in serial monitor.

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

Analyze digital inputs on up to six channels using the ATmega328 (e.g. Arduino Uno / Nano / Ethernet / Mini).

Achieve up to 60% saving on program memory space using Shox96 Guaranteed Text Compression Library for Arduino Uno and upwards.

Arduios is like a OS for the arduino, it enables you to use a sketch in different usecases, without having to upload a new one every time.

In this project, I have shown how to interface a GPS module with Arduino UNO. The data for longitude and latitude is displayed on the LCD.

Start coding online with the Arduino Web Editor, save your sketches in the cloud, and always have the most up-to-date version of the IDE!
