The Arduino is an excellent microcontroller you probably already know that. An Arduino board can however only control low-current devices, so often you need a proper driver circuitry to handle the low-current control signals and […]
Relay is an electromechanical switching device most widely used in the automotive and telecommunication industries. It can be found in cars, washing machines, medical equipment, aircraft, etc. We can see that relays are being used […]
For a while now, I’ve had need of a simple digital to analog converter circuit to be able to work with an Arduino microcontroller. To this end, I had a good search around and eventually […]
For a long time I’ve been wanting to use elegant spotlights in my workshop, and although I have a few issues to take care of, like a simple model and a way to install it, […]
If you’re in a plan to make a minuscule robot, you’ll then need to learn more about a coreless motor. I came across it as a pretty great solution for an upcoming healthcare electronics project. […]
On COVID-19 lockdown days, I came across several motor driver modules in my scrap box in the attic – surprisingly most of them are unused Chinese modules. The L293 Arduino Motor Driver Shield, in particular, […]
Hi there! Last week I finally managed to get an Arduino delivering a 16-bit PWM (pulse width modulation) output from a nifty piece of code. Is the experiment finished? Of course not. Anyway, in this […]
This article covers a simple version of my portable solar power box. In use, it worked flawlessly for me. Although this is a simple version, I am sure someone will be able to improve on […]
Building track lights and spotlights seems to be an obsession of mine. I built my first one in my school days or so, and this time my project thought is on simple power LED light […]
Presented here is the basic circuit of an over-current detector built around a handful of easily available and inexpensive electronics components. This simple circuit for DC devices wakes up when the connected output load draws […]
