The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

Thus those tumbling blocks are hardly demanding in terms of processor power ... such as the Atmega328 in [c0pperdragon]’s Arduino Nano Tetris console should then have no problems, but to ...

Sometimes it seems like Arduino is everywhere. However, with a new glut of IoT processors ... The boards, the Nano 33 BLE and Nano 33 BLE Sense are based on an ARM Cortex M4 CPU from Nordic.
