During Lockdown, I found an old RO cabinet lying around unused. I contacted the RO mechanic and found out the mechanism used to control the flow of liquid in the machine. The solenoid relay which forms the heart of the […]

This once used to be my room, with the setup shown in the pictures. It was a 5.1 Setup based on TDA 7294 with a dual supply of 35-0-35 10 Amps toroidal transformer. With savaged sub woofer from an old […]

Problem Statement: A wireless game is to be designed to implement TIC TAC TOE as popular during school just by using basic digital circuits implementing use of GATES as AND,OR,NAND and NOR logic by total use of ANALOG CIRCUITRY. Team […]

This is another project made after detailed study of acoustics and dynamics of the sub woofer. The system is a 2.1 sound system intended for use with TV, PC, RADIO or any multimedia device .The motivation behind making this device […]

Ultrasonic sensors utilize sound waves to measure distances and detect objects by emitting short bursts of ultrasonic waves, which travel through the air. They generate high-frequency sound waves that are beyond the range of human hearing (typically above 20,000 Hz). […]

A Diy 4*4*4 LED Cube , based on an |Arduino UNO|and 64 LEDS.

What is a joystick?A joystick is an input device used to control X & Y dimensions of any control system to which it is applied. It varies values of the two potentiometers which control X & Y axis respectively and […]

Inter-Integrated Circuit I2C stands for Inter-Integrated Circuit which is a widely used communication protocol in any imaginable electronic device with a microcontroller or a microprocessor . It is a fairly simple protocol as compared to Serial Peripheral Interface (SPI) Protocol. […]

SPI stands for Serial Peripheral Interface, and it’s a way for electronic devices, like microcontrollers, to communicate with other devices, like sensors or displays. One device (i.e. Master) sends a puzzle piece to the other device, and then the other […]
