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 […]
When designing a security system, often we need to add a siren circuitry with it. Fortunately, there are many analog and digital electronics ways to accomplish that chore. However, these days, we can also use […]
As you know, a mercury switch can be used to detect any inclination with respect to gravity. For example, suppose your home security alarm wants to know when someone opens the lid of your cash […]
As promised, here is another fun electronics project for our STEM kids. This time the theme is the setup of an Arduino VCLED Flasher. So, get ready to see a simple voltage controlled lamp flasher […]
