To begin with an embedded development, we’d like a couple of important points with us, that are development board and an IDE (Integrated Development Environment). A microcontroller development board is […]
Easy 1.5V to 12V/24V Converter Circuits
This circuit is basically a step-up DC-DC converter, which permits to acquire 15 volts of output originating from an ordinary 1.5 volt (B1) battery without necessitating the use transformers or […]
Simple Fluorescent Lamp Dimmer Circuit
A typical dimmer intended for incandescent lamps cannot be utilized directly to control the luminous strength of fluorescent lamps. Nonetheless, it could be conveniently modified for this specific purpose by […]
Temperature Meter Using Digital Multimeter
Using this handy circuit, we are able to transform an ordinary transistor and a multimeter (in the VDC scale) perfectly into a digital temperature meter having a range of -30 […]
Solid State 220V to 110V Converter Circuit
Through this functional circuit it is possible to acquire 120 VAC RMS from 240 VAC. Typically, in these circumstances precisely what is employed is a huge transformer for the step […]
How to Make an Opamp with Transistors (BJTs)
In this we learn how to make a simple opamp using a handful of transistors or BJTs, which will work quite like an opamp and can be configured like normal […]
