The project aims to develop a control on two 12V DC motors by using a SN754410NE Quad Half H-Bridge IC. The pin-out of the H-bridge contains a u-shaped notch at one end which can provide help in ...

In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

Instructables member AGBarber has created a fantastic measuring tool in the form of a Arduino powered digital tape measure called the DMW. Which cannot only measure distances on surfaces but can also ...

[SeanHodgins] has a project in mind where he needs to sample over 500 analog sensors. To get ready, he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the ...

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometers ...

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 boards ...

We have featured quite a few cool clocks here at Geeky Gadgets, and the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open-source Arduino digital clock. The DOTKLOK comes with a ...
