Step 8: Led dimmer circuit...
For the dimmer circuit of _one_ lamp, you will need:
- 2x capacitors 10 nF
- 1x transistor BC547(B)
- 1x transistor BC557(B)
- Resistor 5k6 (or 4k6, if you want to dim the leds to zero)
- Resistor 10k
- Resistor 330k
- Potentiometer 50k
- Jumper wire
- Nuts, bolts and spacers to mount the pcb in the casing.
Since we're making a red, green and blue lamp, three times this bill of materials is needed :-s
