Kit Driver Led para Iluminação de Moldura

Informação do fabricante:

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.
