Frequency counter Connection diagram

The circuit includes the TC620 temperature control circuit, the temperature indicator circuit, a thyristor-controlled heating circuit, a vocal music buck rectifier circuit, and the AC circuit. The TC620 temperature control circuit is designed to regulate temperature by monitoring the temperature...

The circuit includes a controller that integrates an acoustic-electric conversion and amplification circuit, a clock pulse generator, a counting circuit, and a control circuit. It manages four accompanying music tracks and flashing lights. Microphones (MIC) convert sound into electrical...

This electronic project circuit diagram for an ice warning and lights reminder system alerts drivers when their vehicle lights should be activated and warns them if the outside temperature approaches zero degrees Celsius. The system employs an LED indicator...

The working principle involves two pairs of photoelectric detection devices installed in the access channel. One side features light source A (transmitter) and photoresistor LDR1 (receiver) at the entrance of the channel, while the other side contains light source...

This device is an upgraded version of the PIC16C71 4-digit LED frequency counter and voltmeter. It eliminates several hard-to-find components from the previous model, which have been out of production for some time. The older PIC16C71 has been replaced...

This circuit measures the distance covered during a walk. Hardware is located in a small box slipped in pants' pocket and the display is conceived in the following manner: the leftmost display D2 (the most significant digit) shows 0...
