Inputs like pinMode ( pin, INPUT ) are very high impedance. No worries. Output like pinMode (pin, OUTPUT) source about 40mA and sink 46mA. Internal impedance 32.5 Ohm sourcing and 22 ohm when sinking.

Nevertheless, it could fill my dorm-later-fraternity room with tunes discernible even over whatever party might have been going on at the time. Distorted? Mebbe. But discernible still. And here’s a ...
