This little post is to refresh your knowledge about the far-famed CD4066B CMOS Quad Bilateral Switch IC. The CD4066B is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. […]
Arduino is certainly a great microcontroller platform for STEM kids as it provides a wide range of learning opportunities for both students and teachers. So, this post is all about making your own smart night-light […]
This post explains how to make a simple touchless live wire detector that can be used to find hidden electrical wiring in a wall or ceiling. This battery powered tester is actually a very simple […]
There are certain applications that require only very low current and loose output voltage regulation. For such applications, a linear regulator made of discrete components is a quick and easy solution. For those who want […]
Bristlebot is a great easy way for kids to start to learn basic electronics. Bristlebot is perhaps the simplest form of a walking robot with a rigid bristle toothbrush body. It seems simple, a Bristlebot […]
Although there are many dedicated sensors and sensor modules to measure current, this post describes the more orthodox method using a shunt resistor! A shunt resistor is a power resistor with very low resistance especially […]
For today’s post, I thought it would be a good idea to see if I could create a reliable soft latching switch mechanism using a handful of electronic components lying around… First of all, note […]
Still, a google search for a commonly available temperature sensor to connect to a microcontroller quickly brings up the LM35. And, copy-paste of a little bit of clichéd code uploaded to the intended microcontroller makes […]
Today, let us have a quick look at the task of boosting dc voltages. It is perhaps worth noting that every other consumer electronic gadget on the market performs some form of voltage conversions imply […]
You may not know the name of one of the first independent semiconductor designers, but you have encountered Hans Camenzind’s designs countless times. Incredibly, he created the 555 timer chip alone, spending a year designing […]
