Specifications
The motion sensor will pick up on nearby hand movements through a small hole (≤ 1mm diameter)
Each panel will have LEDs behind it with 30mm spacing in each direction of the LED (looking like graph paper)
I am a sixth form student, and have no prior knowledge of electronics, but I have practiced building circuits to instruction and am able to solder to a good degree of accuracy. So assembly shouldn't be a problem.
What I need to know, is exactly what I may need to make the circuit work. It will run using mains electricity at 240v, so I assume I will need a transformer to step this down. Also, I would like to know if each separate LED needs a resistor, and how to work out the values of the resistors I may need. For a typical small panel, the number of LEDs used will probably be around 12. For a large panel, this number could be increased to around 50. I anticipate using around 500 LEDs overall.
I appreciate that this is a difficult assignment, so any help you guys can offer me will be highly appreciated.
