Lately, I started thinking about a digital start/stop power switch box. Sure, I could buy one easily but where is the fun in that? In this post, you will find an outline of that small […]
Here you can find the project details of a simple and low-cost pull-pin security alarm. While travelling, rig the alarm unit to your luggage using the alarm security cable. If so, when somebody tries remove […]
I’m sure there’re a lot of electronic gadgets in your house that can be recycled. The good news is most of them can be used again or for another purpose. So, don’t just throw those […]
I finally got around to testing this concept – adding a crosswalk button to the previously published Arduino Traffic Lights project I must admit, I was surprised to find a compact traffic light controller module […]
Arduino provides a number of analog inputs which enables us to measure parameters such as voltage, current, resistance, light, temperature, and so on in the analog arena. In this post, we’ll look at how to […]
In this tutorial, we will learn how to interface a big photoresistor with Raspberry Pi Pico. Since the Raspberry Pi Pico microcontroller provides analog ports, we can easily do a number of projects using common […]
There has been a drastic and steep increase in the number of monkeys coming into my backyard over the last few months. Below you can see a shot taken by my surveillance camera. So, naturally […]
This is an updated version of an old project that was published in EFY Magazine (print) 21 years ago! Now you can see that article here https://www.electronicsforu.com/electronics-projects/solidstate-signal-lamp This time I’m using a minuscule microcontroller to […]
The theremin is an electronic musical instrument with two metal rods (antennas) used to control pitch and amplitude by the human operator using hand gestures. The left rod (a horizontal hoop) reduces the amplitude as […]
