Everyday Practical Electronics - High-Intensity Torch (Flashlight) - n°324 - aout 2006 Build a brighter torch with variable intensity and flashlight options. This design uses a superbright white Luxeon Star/O LED along with an intelligent control design based on a PIC 12F629 8 pin microcontroller. The microcontroller acts as a pulse width modulator to control the l.e.d. brilliance without needing a series resistor. Push switch control for light level. Compact size, construct it in the housing of your choice, or e.g. an old torch housing. |
