Dimmer circuits are always very popular. The twin dimmer offers two independent controls in one unit. A type S576 provides control of each section of the circuit. S576 is an […]
3 LED Running Light Circuit
In this post we learn how to make a running light or chasing light effect using only 3 LEDs, because 3 LEDs are the minimum number required for creating a […]
Designing a MOSFET Power Amplifier Circuit
We know that a design using complimentary emitter follower transistor significantly increases the output power of an operational amplifier. Similarly for achieving highly increased output power MOSFETs amplifier can be […]
Designing Large LED Dispay Circuit
First of all, this project will not seem interesting to every reader. But, this has many possible applications. This is a seven segment display, with a diameter of 280x140mm. The […]
Universal LED Bar Graph Indicator Circuit
This universal pointer or LED bar graph indicator circuit can be used with any kind of input sensor that delivers a exponentially varying voltage. This can be for example from […]
Automatic LDR Switch Circuit with Flashing Lamp
This simple flashing LED light will begin flashing as soon as darkness sets in, and will shut off in the morning when day light arrives back. The operation of the […]
