(Suitable for ages 11 years and over)

This kit allows you to illuminate the edge of a picture frame using a number of LEDs. This happens for a period of time when the button is pressed. The duration is set using a trimmer potentiometer and can be anything from a few seconds to 30 minutes. The student can choose which LEDs they would like to use. These are connected to the terminal block (along with a current limit resistor). The board can drive 200mA, which is about 10 high brightness LEDs.

This kit includes:

  • 1 x PP3 Clip lead
  • 1 x Battery holder (3x AA)
  • 1 x Terminal block (2 way)
  • 1 x Push to make switch
  • 1 x Capacitor, electrolytic, 16V, 220uF
  • 1 x 10M Pot
  • 2 x 10K resistor 5%
  • 2 x N channel FET (2N7000)
  • 1 x 0.5 metre length of single core wire
  • 1 x Picture frame LED driver PCB

PCB dimensions: 58mm x 28mm.

This kit is supplied as a pack of parts and requires soldering.
