Audio Spectrum Analyzer Circuit 100 LED 10 Ch Peak Hold

I made a visually different version of the 10 channel 100 Led Spectrum Analyzer circuit that I used in the 2.1 sound system. The filter quality of the Led Spectrum Analyzer is around 6, and the middle frequencies are 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz. J5 on the circuit changes

Fan Ventilator Speed Control Wind Breeze

The author said to work in the form of “Sea Breeze” for the fan, but I thought of saving electricity. The speed control circuit of the fan works intermittently in the form of a light breeze instead of working continuously. The MAC16N 16A 800V triac is controlled with the MOC3082 Triac Driver Optocoupler based on

230V 3 Phase Inverter with PFC FNA41560 PIC33FJ32MC102

The inverter is fed from a single phase with 230V alternating voltage with a power of about 400W. The output gives a 3-phase voltage of 3x230V. Inverter diagram, dsPIC33FJ32MC102 software, Kicad PCB design are attached. Main control IC FNA41560. There is a PFC power factor correction circuit at the inverter input, which ensures that the

BEKA-MAX Type S-EP 4 Pump Control Circuit (Clone) PIC16F628

BEKA-MAX Type S-EP 4 pump is used for central lubrication of various mechanisms and equipment units. BEKA-MAX Since there is no IMS 559. 392 integrated in the original pump card, the author has made a clone pump control circuit using a PIC16F628 microcontroller. There is a pcb drawing prepared with the source Mplab asm and

Protected Milliohmmeter Capacitor ESR Meter

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 very small in size and its features are very good. In the ESR Meter Milliohmmeter project, the PIC16F690 program was written in MikroC. Proteus drawing,

PIC12F675 Police Siren Circuit Real Sound

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 Ohms, the output power is about 25W. According to the author’s explanation, since the transistors in the Bridge work in switch mode, they do not

Eeprom Copier Circuit

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 detect the type and capacity of the memory. The eeproms supported by the eeprom copy circuit; 24C00 24C01 24C02 24C04 24C08 24C16 24C32 24C64 24C128

Effect Led Stars PCB

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 files. According to the scheme: instead of LEDs through a 1kOhm resistor to the base of the NPN BC547 transistor, then the LEDs are

Animated Heart Circuit RGB Led

The RGB Led version of the Led Heart Circuit Music Box I shared earlier, the RGB LED version of the RGB Led Effect circuit, the PIC12F629 RGB mood light section in the previous circuit was used. There are many working modes in the parallel circuit with 20 5mm RGB LEDs, you can memorize the mode
