There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

Summary This is a C++ library for the Arduino IDE that allows you to manipulate general-purpose I/O (GPIO) pins on your Arduino or Arduino-compatible board with minimal overhead. Many function calls ...

Need to quickly toggle or read some logic signals without the hassle of writing a quick program? [Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to ...

This is a C++ library for the Arduino IDE that allows you to manipulate general-purpose I/O (GPIO) pins on your Arduino or Arduino-compatible board with minimal overhead. Many function calls to this ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

I have a Small Model Railway, 15 buildings, all with 1 LED, some with 2. All connected with an Arduino Nano and a TLC5974 24 channel PWM controller. I used PWM so I could set the desired brightness, ...

A pulse-width-modulated (PWM) signal and the RC-charging characteristics of a weighted-capacitor network can be used along with a CMOS Schmitt inverter to generate a pulse whose width is linearly ...
