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 mouse click of a person. Clicks were made randomly from 800 ms to 1200 ms (delay between clicks) and 150 ms to 350 ms (click…
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…
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…
There are a lot of different soldering stations on the Internet, but everyone has their own characteristics. Some are difficult for beginners, others work with rare soldering irons, some are not finished, etc. We focused on simplicity, low cost and functionality, so that every beginner radio amateur could assemble such a soldering station. A regular…
The dual channel amp volt meter circuit allows simultaneous measurement of 2 DC voltages and 2 currents on the LCD screen. Voltage measurement: 0-100 VDC or 0-10 VDC, Current measurement range 0-10A or 0-1A. The operating voltage of the circuit is between 8v-30v DC and does not require calibration. The heart of the meter is…
USB ESR Meter Circuit The main part of the meter is a ATmega8 microcontroller that controls the entire device. Its main the task is to process measured data and perform calculations so that the result is real ESR value. This value is displayed on the LCD. Another task of the ATmega8 microcontroller is communication with…
The presented layout is a snap on a computer for measuring DHT22 temperature and humidity. It measures the temperature from -40 to 80 ° C with a resolution of 0.1 ° C and accuracy of 0.2 ° C and humidity from 0 to 100% with a resolution of 0.1% and accuracy of 2%. The device…
Just shared STM32F40X microcontroller atmega8 to control a power source according to the project feasibility project, it’s made with more power in the sight of ola, p-channel mosfet irf5305. That’s how things work in 2 different high-efficiency low-voltage 24…30v high-voltage buck and Boost LED indicator for voltage and current used in the display. Gerber PCB…
Coil winding machine based on the Atmega8 microcontroller motor driver for stepping motor is used on the floor of the L293 used on any sensor makes the calculation according to the indicator used for LCD WH0802 for keypad 12 buttons used. Automatic Coil Winding Machine, belonging to the CVAVR source code proteus isis simulation file…
Led Clock Thermometer circuit based on the appearance of a lot of trouble, but construction of the ATmega8 microcontroller is very beautiful like a 900 LEDs used LEDs positioned on the plate tabelarda Atmega8 outputs there are outputs 4 x 74HC574 is IRF8910PbF (two single package mosfet of smd so8 sheath) mosfet powered through the…
