Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The 7-segments LED devices The general principle behind this kind of devices is the same that makes the common LEDs working. To get a LED lighting we should connect its ground pin to the circuit GND ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

We got it running on an Arduino Leonardo the quickest, because it has support for Serial1(). Don’t be discouraged by these glitches in this rev 0 deployment — [Eric] has really made quite a ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

This week I will outline a project for Halloween that uses the Arduino and a light to create a glowing effect inside a pumpkin. I use artificial pumpkins for projects like this so I can reuse them in ...

Inspired by its professional range, Arduino has put dual Arm cores, Wi-Fi, Bluetooth LE and 76 IOs into its Mega form-factor. The new board is called Giga R1 WiFi, and has an Arm Cortex-M7 running at ...
