GCSE RM Project - how to create a circuit to power 8 LEDs

Discussion in 'Design and technology' started by remyk69, Feb 3, 2012.

  1. Without making a PCB, you could do this using copper tape, available from many picture framers.
    The circuit needs to be parallel, you have described series.
    Use 2 pieces of tape, top one +ve, bottom one -ve.
    Solder all +ve legs to the top track and all -ve to the bottom track.
    Solder a battery snap to the tracks and add a 220 ohm (red,red,brown) resistor across the tracks, this will let all LED's light up to full brightness.
    We did something similar to this last year in a circle around the face of a clock.
  2. Send PM with email and I can send you a picture/advice.
