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 ...

Control and read I/O pins on an Arduino by sending simple string commands over serial com port. Incoming data to the Arduino is sent as a series of four comma-separated numerical characters bound by ...

The Arduino Monitoring and Control System is a simple Arduino-based program designed to read analog sensor values, control digital outputs, and display information on an I2C LCD display. The system ...

Charlieplexing is a technique of controlling many LEDs using a few I/O pins. Charlieplexing is same as multiplexing, but it uses the tri-state logic (high, low input) to reduce the number of pins ...

Arduino GIGA R1 WiFi board brings the STM32H7 dual-core Cortex-M7/M4 microcontroller found in the Portenta H7 boards to the larger Arduino Mega/Due form factor with up to 76 GPIO pins. As its name ...
