Program Arduino boards without using traditional USB cables.
by Shubham Shinganapure
Voltmeter can measure voltage up to 50VDC. It automatically calibrates when voltage of power supply is unstable.
Project tutorial by IoT_hobbyist
Connect up to 10 buttons using a single interrupt.
Project tutorial by Svizel_pritula
Easy to use interrupting thread handler. Does not relay on yield() or delay(ms) for switching and no pre-allocated stack needed.
Project tutorial by Adamb314
A single Arduino Uno/Mega can carry up to 14 RS-232 boards. Each board is distinguished by ID, which is set via a DIP switch.
Project showcase by phpoc_man
This project illustrates switching using a transistor.
This project demonstrates the working with Shift Register.

Arduino's great, but how in the world do you do two (or more) things at once on separate intervals? You need protothreading!
Project tutorial by Drew Alden
Clock LCD display adjustable.
Project tutorial by Tittiamo
We used a TI FDC1004 breakout with an Arduino to measure liquid level in a bottle using the capacitance between two adhesive copper strips.
