12W Hifi Audio AmPlifier Circuit using TDA2616

Electric Circuit Diagram light flash using NE555 and 2N3055 Circuit Diagram uses a 555 timer IC working as an astable multivibrator. The flashing rate can be varied from very fast to a maximum of once in 1.5 sec by varying the preset VR1.

Color sensor is an interesting project for hobbyists. The circuit can sense eight colors, i.e. blue, green and red (primary colors); magenta, yellow and cyan (secondary colors); and black and white. The circuit is based on the fundamentals of optics and digital electronics. The object whose color is required to be detected should be placed […]
