Hi guys, I’m developing a little gadget based on Arduino Nano v3 and I’d like to prevent others to read, modify or overwrite my sketch... I thought I could fill with a black resin my box but what about the code and the usb access? On usb I need the serial monitor working so just disable (se or hw)…

How to prevent reading my sketch?

Thanks, can you help me with that code protection and lock bit? How to set it?
