Raspberry Pi Pico is a microcontroller board from the Raspberry Pi foundation. It is an exciting new microcontroller board launched on January 21, 2021, based on the RP2040 micro-controller by the Raspberry Pi Foundation sporting […]
Arduino & Square Wave Thoughts
The theory behind generating square wave is almost a trivial thing! A square wave is a signal that changes between high and low state where the primary requirement is that the on-time (high state) and […]
Reverse Voltage Defender – Design Ideas!
This article shows you how to use reverse voltage protection with minimal power loss in your electronics projects running on a battery/DC power supply. In fact, for a long time, I wanted to put together […]
Table Clock Adapter for Electronics Projects
We’ve controlled electrical appliances through a number of wired and wireless control methods. That’s okay but how about controlling them with the alarm signal of a cheapo quartz table clock? This article demonstrates the simple […]
Self-Timing LED Lamp
Looking for a simple way to make your own automatic LED lamp for your staircases or corridors? This simple self-timing LED lamp gives you a defined light output at the exact time you need it. […]
Power MOSFET Load Switch
A while ago, I designed a Power MOSFET Load Switch circuit using a handful of components that I use in little power electronics projects to allow a regular slide switch to control power on/off function. […]
Simple Clap Switch/Blow Switch – Do It Yourself
I get a lot of requests to publish simple clap switch projects even in this wireless and internet of things era. Of course, there are countless projects available across the web, and hobby/educational kits are […]
Automatic Entryway Light Controller
Equipped with a magnetic door sensor, this entryway light controller automatically detects the status of the gate or the entryway barrier to control the entryway light. Moreover, day/night status is monitored by a photosensor so […]
