What can you do with Opto encoder?
It may have a mighty low angle resolution. If you can dig up this information, may be interesting.

I2C or serial communication between TWO atmegas of 3.3V and 5.0V
Put a resistor between. Not too small, though, because you will supply current into 3.3V device. Try 1k, and mind: it deteriorates I2C speed.

Arduino compiled binary problem
True, our forum can not be tricked on numbers, but he was dormant... until now. I said 'we congratulate'.

Programming chip connected to external power
Logic Probes, they show High, Low, and also Pulse (if no pulse, not serious).   Here are my choice among many: https://www.allaboutcircuits.com/worksheets/design-project-...

Forget the scope, my experience is that a Logic Probe with LM358 is fast and good enough (for most Pin debugging).

8M internal oscillator, what you know about, it is the most important data every designer starts with. Do divide 8M : 8 (it is a prescaller) : 1024= 976Hz which frequency your LED...

Programming chip connected to external power
Proceeds, you can learn a lot. Use fast PWM 10b, with 8M internal osc the max pulse is 1ms. Set OCR values for color and level. Mind, that NMOS does have 1300pF in Gate, thus,...
