Want to remove the hassle of using command-line every time you need to upload a new firmware? Now you can!

A Bluetooth multimeter capable of resistance, voltage, current and continuity measurement. Made with Arduino Nano.

Easy to use interrupting thread handler. Does not relay on yield() or delay(ms) for switching and no pre-allocated stack needed.

Connect up to 10 buttons using a single interrupt.

I found the Arduino Leonardo to be a great way to manage my CNC machine with little programming effort.

DIY Arduino hot air SMD rework station.

With this simple circuit the analog output of Arduino Due start from zero

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

The soldering iron controller based on arduino that implements PID method to keep the temperature of the iron.

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

Extension to Ben Eater's breadboard computer that allows saving/loading programs and works as a monitor, assembler and disassembler.

A bit more accurate than __TIME__.

This Arduino-powered Web Oscilloscope supports trigger, and changing voltage/div, offset and time / div. It supports 6 channels.

Get not only 5 volts but also 9, 12 volts (18 Watts max) out of any QC-compatible charger/power bank for supplying power hungry projects.

In this tutorial I will explain how to use the TIMER0 of Arduino

A voltage to frequency converter can realize an opto-isolated analog input for Arduino or other microcontroller systems.

A cheap (less than $20) signal generator that can produce a sine wave, up to 70MHz (Though practically 20-30MHz).

This micocontrollers laboratory is designed to speed up projects, and make easy and clean connections.

Training board for essential logic gates.

A programmable, portable, rechargeable power supply based on Arduino featuring an OLED display for viewing V.I.P. of projects/prototypes.

More complex microcontroller projects often require a menu-driven interface. This library for XOD can help autogenerate them from a diagram.

Power management for portable Arduino projects.

We live on a beautiful planet called earth, do you know how much is its weight? Lets find out.

You need to send a command to Arduino.
