I propose a standard sketch (arduino_pins.ino) that outputs the numbers of the most predefined pins via serial. The output is then put into a .txt file. Finally a script (analyzePinList.py) runs over ...

After your arduino will send you Configuration done!, you can start controlling your pins. Sending high or HIGH will ask you to input a pin number that should be put on high. Writing low or LOW will ...

For example, you can control 12 LEDs using 4 Arduino pins 4*(4-1) =12. LEDs are diodes, and in diodes, current flows in only one direction. So in Charlieplexing, we connect two LEDs in parallel with ...

It transpires that folk have been busy writing ‘cores’ – the name for code that adapts Arduino code to run on different hardware – for several other bare chips, and some have 20 pins – plenty. Have ...

Arduino is strictly bootloader, and a bootloader cannot change fuses. “How do I reconfigure the IDE so that I can use these additional two pins.” The same way you SHOULD use the other pins.

We also define some other boolean-type variables that will hold the status of the pins. /* Arduino pins where the LED is attached */ #define LED_1 2 #define LED_2 3 #define LED_3 4 #define LED_4 5 ...

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 ...
