There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...
In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
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 ...
Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...
[Jarek] found a non-functional robotic arm sitting around and wanted to get it working again. By adding a few custom boards to an Arduino he managed to do just that. The arm is driven by six stepper ...
