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…
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…
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…
In Vu meter circuits, the LEDs give light according to the level of the sound signal. In this circuit, the LEDs give light according to certain frequencies (various calculations and PWM control). Led colorful music circuit, dance lights or disco lights project made with ATtiny13 microcontroller. It allows the LEDs to light up according to…
This study deals with the problems, structures, controls of industrial robotic arms and their role in Industry 4.0. The study describes the development and realization process of an industrial robotic arm model with 3D printing. Besides building the model, the job deals with firmware, software and inversion kinematics which are crucial for control. Detailed and…
The vu meter circuit, which can operate peak hold and normally, has a 2×20 LED peak indicator. Leds are controlled by Atmega8 microcontroller. The display range is -34 to +4 dB. The LEDs are controlled by multiplexing 4 LEDs in 10 steps, the multiplex frequency is about 100Hz. R1 … R4, their resistor (270-ohm) limits…
I tested the Joke Remote on Samsung, Toshiba, Arcelik, Vestel televisions. It can turn on and off. Arcelik TV was a very old model, it only turned it off. 2021 model toshiba also turned it on and off when the button was pressed. Keep the button pressed when the TV does not turn off. There…
Mobile line compatible DTMF relay control project made by arranging the fixed line DTMF relay control project of my @ETE teacher. ULN2004 for relay driver used CM8880 IC for DTMF receiver installed on circuit PIC16F628 microcontroller. It has Proteus pcb, simulation, picbasic source and hex codes. Working Logic of DTMF Relay System First of all,…
The Strobe Led Lamp circuit has 16 effect modes selected with the button built on the PIC12F675 microcontroller. Since the selected mode is stored in the integrated eeprom, the selected mode remains in memory when the power is cut. The source is Picbasic Pro software. You can adjust the lighting times of the LEDs and…
I shared the ATmega88 microcontroller Led Heart circuit years ago. The LED Heart circuit that I have applied is controlled by the ATmega8 microcontroller. I made a lot of decoration on the PCB top floor and the PCB was made more useful for additional circuits. In the LED heart circuit, 22 ports of ATmega8 (ATmega8A-AU…
