HIGH POWER LED MODE LAMP
This high power led mood light is based on PIC16F628 and the ability of this mcu to produce PWM pulses. Varying pulse width we can produce millions of color combinations using only the three basic colors. So only one RGB (Red-Green-Blue) led is capable producing a rainbow of fading colors.
PARTS LIST:
Here is a list of the components I used for making the led mood lamp.
- 3 x NPN transistors capable of driving 500 mA, for example the
BC337
- one PIC 16F628(A) and a programmer
- a small perforated circuit board
- 7 x 10K resistors (1/4W)
- some 1 watt resistors (4,7, 10 and 15 Ohm) and a DIP switch
- a power supply (5 volts, 500 mA)
- Ikea Mylonit lamp or other housing
- silicon paste from your local DIY shop
- one z-power 3 watt rgb led
- a little heatsink and some cooling paste
