555 IC Astable multivibrator circuit

The transmitter described here includes an additional RF power amplifier stage following the oscillator stage, which increases the output power to 200-250 milliwatts. When connected to a properly matched 50-ohm ground plane antenna or a multi-element Yagi antenna, this...

Capacitors C1 and C2, in conjunction with a speed controller, function by receiving voltage at the gate of the MOSFET. When the voltage on C is applied, it activates the operation of the MOSFET. In this circuit configuration, capacitors C1...

A PIC programmer circuit that operates using long cables from a PC to the programmer. The PIC programmer circuit is designed to facilitate the programming of PIC microcontrollers via a connection to a personal computer (PC) using extended cabling. This...

This is a digital dice circuit that uses the PIC16C84. The digital dice circuit utilizing the PIC16C84 microcontroller is designed to simulate the random rolling of a standard six-sided die. The circuit operates by generating a random number between 1...

This is a simple 555 timer circuit suitable for oscillating applications. To slow down the strobe effect, replace the 220 µF capacitors with 1000 µF capacitors. For a faster strobe effect, use a 150 µF capacitor. Additionally, R1 can...

A monostable multivibrator is being designed to utilize the output of an infrared circuit to trigger a relay for a specified duration using a one-shot configuration. The monostable multivibrator, often implemented using a 555 timer IC in monostable mode, serves...
