hi there people,
i am still very new to this forum and arduino so bare with me. i am currently working on a midi controller pedal board and have tried a number of different things so far. my question today is- i want to use 8 switches (momentary) from an arduino uno r3 and would like to each send a seporate midi note, however i would like to also use an led for each switch that stays on until the switch is pressed again and it goes off. example: swicthed pressed 1st time, send midi not and led is on, press the switch 2nd time and no midi note and led goes off.
is this possible with the uno r3 or do i need more inputs/outputs like an arduino mega? and iff possible how would i go about it.
