Electronics Projects Circuits

@Kapibara shared the battery desulfator circuit for battery resuscitation, recovery of the dead battery, I made a similar desulfator circuit for battery repair and tested for a long time. NE555..

ESR meter is a device used to measure the equivalent series resistance (ESR) of capacitors. Built on the PIC16F690 microcontroller, the previous version uses PIC16F873A) The ESR meter circuit is..

Siren circuit is built on the PIC12F675 microcontroller, and the outputs of the PIC12F675 are powered by a 6-transistor bridge amplifier. Considering that the resistance of the siren is 2..

I will give information about how the HC-SR501 PIR motion sensor module works, HC-SR501 Features and its use with LDR. The HC-SR501 PIR sensor module can be used not only..

Eeprom Copier Project with LCD display, made with PIC16F648A microcontroller, provides rapid copying of serial EEPROM memories of series 24 (with I2C protocol) without a computer. The eeprom copier can..

ATtiny13 Led Stars There are source PCB drawings, Source and hex code files, Proteus simulation files. Added transistors to increase the number of LEDs. There are three printing options in..

The dimensions of the PCB board are 80×80 mm. Each board is equipped with its own protection device that disconnects the load in emergency situation (appearance of constant voltage at..

LM3915 The connection stands and falls with analog amplification and filtering of audio signals using operational amplifiers. The audio signal is first amplified and impedance separated by connection with the..

Actually, I implemented the power supply circuit with limited possibilities, but it is sufficient for me, the first tests were done successfully. Since I have a toroidal transformer with an..

First and foremost of all is to change if the problem continues, 74HC125D to 74HCT125M in your carparog. I attach 2 versions, the first one worked for me, the second..
