Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need. The ExtraCore library comes ...

Then, an Arduino board might be exactly what ... and Bluetooth module since they connect to different pins (the Wi-Fi shield to the SPI bus, and the Bluetooth module to the TX and RX pins).

The 30-pin SIMM shown above ... to your chairs…) 16MB but due to limited amount of available IOs on the Atmega328p only 256KB can be used. Our guess it that an SPI / I2C IO extender could ...

The Arduino Mega's PWM pins are digital ... On the Uno, Nano, and Mini, the PWM pins are on D3, D5, D6, D9, D10, and D11. On the Giga and Due, they're on D2 to D13. Some boards like MKR1000 ...
