interactive radar

its a radar that detects light using a servo a LDR. it also has a 8*8 led module that shows where the radar is pointing. If there is an object in the way, then the buzzer beeps fast and in its resting position, i beeps every second. The servo spins back and forth 180 degrees and you can manually control it using a joystick. I am going to print a mount for all but i have no money for filament.
