Sometimes it’s necessary to make do with whatever parts one has on hand, but the results of squashing a square peg into a round hole are not always as elegant as [Juan Gg]’s programmable DC load with ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

Using an Arduino Arduino Uno along with an nRF24L01 module for control together with a 3D printed shell Dejan over at the Mechatronics website has provided details on how to build your very own DIY RC ...

If you’ve been reading this blog for a while, you’ve probably seen us refer to the Arduino microcontroller on a number of occasions. This little circuit board is at the heart of many DIY projects, ...
