Hello :-) I wrote small oscilloscope for my Arduino Mega2560 (but UNO too), based on some projects for N-3310 LCDs. Use Nokia-3410 display for more space. There is 4 buttons, two for setting timebase, one for HOLD function and last for change sensitivity. Timebase has 6 steps (1-2-5-10-20-50 ms/div), and fine tunning with potentiometer. HOLD freezes display (and stops reading samples), sensitivity changes internal reference to 1,1V or 5V (and - for MEGA2560 to 2,56V).
Schematic and *ino in attachment.
