XC6119 Voltage Detector With Delay Time Adjustable

The 555 Timer Time Delay Circuit uses LEDs to visually indicate the status of the circuit at any moment. The operation begins when the reset switch, SW2, is activated. The 555 Timer is a versatile integrated circuit widely used for...

Operating at approximately 1.1 GHz, the detector senses disturbances in the electromagnetic field surrounding the antenna. The Doppler signal generated by detector D1 is amplified and used to control a power MOSFET switch. The antenna consists of a short...

This is an intriguing 555 timer circuit designed to entertain and engage individuals while studying electronics in educational settings. Commonly referred to as a clap switch circuit, it operates as a sound-controlled flip-flop. This sound-controlled light can also function...

This circuit utilizes the FET 2N3819, which functions as a switch, operating in both conduction and non-conduction states. This behavior is in contrast to that of a bipolar transistor. The 2N3819 is a Junction Field Effect Transistor (JFET) known for...

The site features several low-power transmitters, but until now, there has been no receiver. This circuit can be utilized to scan an area or room, indicating whether a surveillance device is active. The challenge in creating an effective detector...

A reflex isolator detects the presence of an object by reflecting light from the object back to the sensor. This technique is effective when an object is in close proximity to the sensor. Reflex isolators, also known as proximity sensors,...
