The remote control transmitter consists of a DTMF generator and an FM transmitter circuit. A UM91214B phone-specific integrated circuit (IC) is utilized to generate the DTMF signal, with a 3V power supply provided by a 3V zener diode (D1)....
The automatic weapon features a magnetic switch circuit that is simple, reliable, has a low failure rate, and offers good versatility. It can be used to output performance or convert mechanical displacement. The circuit diagram utilizes a Hall switch...
Voltage is applied to the chip via pins 14 and 7 so that when power is applied to the project, the high and low frequency oscillators will come into operation to produce a wailing sound from the piezo. The...
An electronic dice is a classic introductory project for individuals interested in electronics. It consists of a timer, counter, and several LEDs, forming a circuit that adds an engaging element to traditional board games. When the switch is activated,...
The time delay, T, in seconds is calculated using the formula: T = 1.1 x C1 x (R1 + R2). The resistances are measured in megohms and the capacitances in microfarads. The combined resistance of R1 and R2 should...
This project originated from the necessity to remotely control audio-visual equipment located inside cupboards. RF-based commercial units such as those used for... The project aims to develop a system that enables the remote operation of audio-visual devices housed within enclosed...
