Description on how a metal and plastic bottle/can separator will look like. More description the better to visualise as I need my friend to draw out. So for the top it can be square or half pentagon work. There will be a hole to put in the bottle. out top of the hole has the LED and below it is the LDR sensor. Outside on the side of the hole is the keypad and LCD At the back of the hole is the DC motor rotating in a gear that will switch the piece of cardboard left and right Then at the entire back of the machine it will be a button to press for the servo to open the lid for worker to colelct the bottle See more
