Will this this schematic modification work?
The original circuit has the indicator LED wired in such a way that could destroy it, and while the overall design could work, it's certainly got problems. Your replacement of that LED with R1 (I ...

Will this this schematic modification work?
After leaving a few comments, I think I have enough for an answer.
The raw circuit that you copied from has some problems, related to not having any kind of current limit for the indicator LED. The ...

Will this this schematic modification work?
Both circuits are not good. The two transistors are connected as common collector, that means they provide zero voltage amplification. So the Mcu will see a very small signal change between dark and ...

How to properly read values from CCD linear sensor?
TL;DR: I think you're reading the CCD out way too slowly.
A CCD is fundamentally a dynamic device -- data is stored as varying amounts of charge on tiny internal capacitances.
The datasheet that I ...

IRFZ44N , PWM signal from Atmega328P always conducting
Thanks for all the answer!
I replaced it by an IRLZ44N but it wasn't working either. I didn't put a common ground between the arduino and the 24V source, so that's why it didnt work. The moment i put ...
