This is a simple arduino sheild that can run on it's own as an arduino uno once it's powered up using the power input. to upload a code, simply remove the **ATMEGA328p** from your reguar arduino board and place this sheild on top of it. Then plug ur arduino board and upload a code.If you want to burn the bootloader of ur ATMEGA328p chip, then udon't have to remove ur ATEGA38p chip from ur regular...
Modern earphones are not just (stereo) speakers, but they integrate a microphone and few buttons. All these components are available through a 4-pins 3.5mm plug (also known as TRRS). This schematic shows you how the microphone and buttons are connected through this connector. The common purpose of these buttons is music control, but in general, their behavior depends on the specific application. F...
Since somyone really cares about this project, I made it more readable ：）
This board contains:
Motor Drivers: Contains two l298n to drive two 550 motors, each chip allows 2A current, and 550 motor uses up to 3A current, that's why I made this special board to drive them. I fit the most common heatsink just onto these chips, CHECK if it fits your heatsink. They are critical.
This afforable Geiger Counter that works as standalone device and also can connect to other external devices (like RaspberryPi/Arduino or other GPIO devices) to send the "clicks" thru GPIO interface.
The Arduino code for the Geiger counter is available here:
- Pin D2 --> Arduino interruption
- Pin D7 --> Buzzer
- Pin D8 -->...
> I got a lot of messages about the project, or the code, but the situation was I put the project on hold for a while, when waiting for parts to arrive, then modified multiple times without documenting etc... the project got finished working well, heat up quickly, but when I have time I will make a fully documented mark 2 version.
I want present to you my new version of the Bluetooth module for a car, home whatever you want.
This module base on the BK8000L module with an additional power scheme for working with car voltage. But it’s also can work by USB.
You can ask me why need to create something new if you can easily buy already exists solution from China?
Here are some pluses:
1. It works.
2. Noise reduction fr...

**Open Solar Energy Diverter**
This project have the aim to divert not comsumed electricity produced by photovoltaic panel to water heater to keep energy produced in the area of usage.
This project is base on idea from [http://energie-autrement.blogspot.com/p/plans-eolienne.html]...
# HOME PROJECT WEBPAGE #
# Version #
Just replaced 2x TL082 to 1x TL084... Added diode bridge on power supply.
CD Changer Emulator for Nissan Maxima, Pathfinder and Infinity I30. Allows to play mp3 and wav files from USB stick and micro SD card. Pretends to be cd changer to head unit, therefore all head unit and steering wheel controls supported. Based on DFPlayer Mini board and ATTiny85.
