In electronics, an LED circuit or LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.Build an LED Bargraph Optical Tachometer stefanv
For the electric R C enthusiast, a tachometer can be a very useful piece of equipment. When I first built this tach back in 1995, it was essential, as there were very few off the shelf electric R C power systems that just worked.Contactless digital tachometer using 8051. 3 digit display ...

THE POWER SUPPLY Sometimes you will see a circuit as shown in the first diagram with 12v or 12v on the top rail and 0v or a negative sign or the word "negative" on the bottom rail. In this case the word negative means earth or "chassis of a car" and we commonly refer to this as "negative earth" or "negative chassis." In the second diagram, the output from a power supply has a positive 12 ...200 Best Electronics Mini Projects: Circuits, Working ...
Best electronics mini projects for electronics enginnering students, here we gave a complete information of the project along with circuit digaram, code, working process and step by step methods of making and how to do it.DIY Tachometer using Arduino Circuit Digest
Tachometer is a RPM counter which counts the no. of rotation per minute. There are two types of tachometer one mechanical and other one is digital. Here we are going to design an Arduino based digital tachometer using IR sensor module to detect object for count rotation of any rotating body. As IR transmits IR rays which reflect back to IR receiver and then IR Module generates an output or ...Tachometer
A tachometer (revolution counter, tach, rev counter, RPM gauge) is an instrument measuring the rotation speed of a shaft or disk, as in a motor or other machine. The device usually displays the revolutions per minute (RPM) on a calibrated analogue dial, but digital displays are increasingly common. The word comes from Greek ταχος (tachos "speed") and metron ("measure").Oscillator operation working feedback circuit, block diagram
