The Electronic Bird, Rodent Repeller is a highly effective and environmentally friendly device for repelling birds. With a sound level exceeding 100dB, it can repel not only birds but also..

A circuit that makes mouse clicks at random times with ATmega8 microcontroller instead of programs known as Mouse Clicker or Automatic mouse click. To make it look like a real..

STM32F103, STM32F303, ATmega32, ATmega328p Amplifier control project is a control module for your audio amplifier. It supports various I²C/SPI controlled sound processors and FM tuners. All source codes and PCB..

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..

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..

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..

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..

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..

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..

In addition to measuring voltage, current, power and temperature, the meter can also calculate the resistance of an attached load. However, this is not the most important difference – more..
