This repository contains full PCB design of Arduino UNO. This design was done completely from scrath, starting with selecting components from digikey, creating schematic symbols, creating footprints, ...

Starting with hardware, the Arduino Mega is based on the Atmega2560 microcontroller. In the iteration that is found on the Mega board, the microcontroller comes in a standard TQFP 100-pin package.

Last but not least, the bootloader firmware. This was done using an Arduino UNO working as master and the newly created the Arduino Nano clone as target. After that you’re set to go.

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

In the 18-LED flasher, nine outputs of Arduino Uno are connected to the bases of transistors T1 through T9 via resistors R1 through R9. The outputs go high and low after a predefined time. As before, ...

DIY Arduino Wind Speed Meter – Research A quick bit of research online provided a wealth of ready-made weather stations you can purchase ranging from £40 or $50 up to and above $500.
