This little post, as the title suggests, shares some random thoughts on system voltage supervisors and related things! Supervisory Circuit Supervisory Circuits are electronic circuits that monitor one or more parameters of systems such as […]
This post shows how to get started with a quite popular and comparatively cheap color TFT display module with an Arduino Uno. To start this experiment, you need the following key components. Arduino Uno R3 […]
As Maya Angelo, an American civil rights activist and poet, once said, Do the best you can until you know better. Then when you know better, do better! So, here’s a review post to keep you […]
The post was created some time ago and I’m not sure if things have changed, but it worth a shot! Back in January 2020 I picked up one Philips DLP6006B 11000mAh Li-Ion Power Bank on […]
There are times when it’s astounding to be able to make a programmable shunt regulator, perhaps using obsolete components from your junk box. Recently, I used a modest little circuit to do that thing; the […]
The Raspberry Pi Pico is a feature-rich microcontroller! Its low cost and wide availability make it a great microcontroller for our everyday electronics projects. Python and C/C++ are lovely for programming the Raspberry Pi Pico […]
When you want beautifully smoother color transitions, a better way to do it is to try HSL or HSV rather than just driving LEDs via RGB colors. So, this little post is about controlling RGB […]
Some time ago I had posted a couple of Arduino projects that work in conjunction with external power supply circuits. If you have not already got those ideas yet, you may simply go through the […]
I bought a cheapo Chinese automatic LED nightlight a while ago. Working on this “automatic color changing night lamp” is pretty simple. A photoresistor (LDR) turns the LEDs on when it sees darkness and off […]
Selfie Stick is a common smartphone accessory nowadays! The word “selfie” first appeared in an online forum in 2002, and in 2013 it was named the Oxford Dictionary Word of the Year, defined as “A […]
