The aim of the project, step-down transformer is to show Electrical and Electronics Engineering, could step-down the voltage from 220v to 24:12v, and fro this project write up.… Continue Reading
The project work is on the design and construction of automatic two lane traffic light control. This system is based on digital electronics. It employs an astable multivibrator which is the clock generator that sends the clock into a time sequencing generator using a decade counter with ten (10) decodes output that has it’s binary… Continue Reading
Amplifiers, which are devices that increase the gain of an audio signal, dominate modern audio technologies. In this project, we designed and built an audio amplifier from scratch in order to demonstrate that such a key device can be constructed using basic electrical engineering principles. After performing major circuit calculations by hand, we… Continue Reading
