In this touch operated potentiometer circuit we have two touch pads, which produce a slowly increasing voltage at the output when one touch pad is touched, and a decreasing voltage when the other touch pad is touched. When the touch contact is removed the voltage holds at that particular increased or decreased level “permanently”. Touch […]

Modifying XL4015 Buck Converter with an Adjustable Current Limiter
In this post I have explained a simple way to enhance the the XL4015 DC to DC buck converter with an adjustable current limiter, which seems to be missing in the original module. About XL4015 The XL4015 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, specially designed for operating a 5 V, […]
Switching Boost Converter Circuit using IC MAX732
The proposed boost converter circuit using MAX732 IC will allow you to have a continuous voltage of 12V with a current of 150 or 200 mA. The input voltage can be between 4.5 to 9 V, which can be produced by three 1.5V batteries, for example. The circuit is quite simple, we will be using […]
RTD Temperature Meter Circuit
In this post I have explained the making of an RTD temperature meter circuit, and also learn about different RTDs and their working principles through formulas. What’s an RTD A RTD or resistance temperature detector works by detecting the difference or an increase in the resistance of the sensor metal when it’s subjected to heat. […]
Mobile Phone Controlled Door Lock Circuit
Controlling your door lock through your personal cell phone was never this easy. Learn how to build a simple electronic circuit that will help in converting your ordinary door lock into a high security door lock which can be now controlled through your own cell phone. Your ordinary door lock can be now very easily […]
Simple Analogue Weighing Scale Meter Circuit
Learn a super simple procedure to make a weighing scale meter circuit useful for measuring smaller magnitudes of weight. The Concept The concept is very simple, a light beam is allowed to pass through a linearly colored ribbon and fall over an LDR. The color shade of the ribbon positioned in front of the light […]
