Arduino Nano Dev Board
PureZX Dec 08,2022
Arduino Nano dev board that I designed a while ago, someone might find it useful. The board breaks out all Nano pins to turned pin SIL or SIL header pins (the types used are optional, use du-pont, 1mm solid core wire etc). Also has onboard addition 1A 5V supply and easy connect servo headers. There are 4 LEDs, 4 buttons, 2 presets and passive piezo buzzer all accessed by SIL connectors. There is also space on the PCB for one of the small half height breadboards and an OLED 128x64 display. Compon...

Atmega328 digital panel meter volt ammeter
zvonacfirst Dec 07,2022
The panel voltmeter that is the subject of this project was developed as a personal necessity.Instead of the classic solutions, already known, the chosen solution was the use of an analog-digital conversion module (ADC) 4 channels 16 bits - I2C - ADS1115.Specifications:- dedicated software with parameter configuration and calibration menu with saving in eeprom- the voltage range is up to 50 V configurable- the current range is up to 5A configurable- voltage, current, power and temperature displa...

Arduino Transmitter&Receiver (1)
Smart Dec 06,2022
It is Arduino and NRF24l01 based radio comminication board. The board contains 3 modules, First one is Arduino Pro Mini based transmitter, secod one is Arduino Nano based receiver and the last one is Raspberry Pi Pico based receiver module. You can use this board to control your electronic devices(RC Car, Drone, Robots,... etc) remotely. You can watch the build video from my youtube channel. Video link is, https://youtu.be/x8mul0Das2k

GRBL ARDUINO UNO SHEILD
sakaic Dec 06,2022
Needed a simple board to help with retrofitting and existing machine with a proprietary controller with a Arduino Uno GRBL based system so that it would be easier to maintain. Uses PC817 for optocouplers and LM7805 regulators for ease of building.

Focus Stacking Circuit For Macro Photography
Curious Scientist Dec 05,2022
This circuit is mainly designed to serve as a tool for shooting pictures for focus stacking macro photography. But it is actually a simple stepper motor driver panel which can be used for other purposes where we want to program the movement of a stepper motor.Focus stacking is a nice technique to increase the depth of field of a -typically macro, but it can also be a landscape- photo. One takes several images focused on a different spot of the field of interest and then combines the "sharp parts...

Arduino_LCD_Project
engineer Dec 04,2022
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3. x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
