[Kaushlesh Chandel] prototyped a few projects on his Arduino that use an HD44780 Character LCD. Wanting to keep these projects in one piece, but not sacrifice his Arduino board, so he etched his own ...

After you’ve taken the plunge and decided to learn how to etch your own circuit boards, you’ll quickly find even the simplest boards are still out of your grasp. This is due mostly to the two-layer ...

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it uses rgb LEDs that are controlled by an Arduino-based microcontroller that ...

(**) speaker pin 2 output is connected to speaker pin 1 on DevKit hardware. To prevent the IO pins from possible damage, speaker pin 2 should NOT be configured as an output. (****) When using serial ...

An Arduino is by no means expensive, but that still doesn't mean that it suits your needs right out of the box. If you want to make your own custom board, Make shows you how in a three-part series.

Need more Arduino board? Do not spend more money for another one. Why not try to build your own DIY Arduino board? It is easy and simple. Now I will address one of the issues of making your own ...

Arduino 3D Printer project is a DIY 3D printer design based on an arduino board. It features RAMPS 1.4 shield and Arduino Mega 2560 that handles majority of the 3D printer components. It has an ...

(****) When using serial flash with the Pro Micro standard wiring, OLED_CS (chip select) cannot be grounded (always active). In this case a simple circuit with a general purpose PNP transistor and two ...
