Re: Re: LED's - limits for serial wiring | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

With the LEDs I'm driving with PWM, I just have a 2R2 resistor for each group of six. Even though the current through the LEDs is 250 mA, the input current is about 10 mA from the supply. A lot of that is taken by the MCU, clocked at 4 MHz on the prototype. I'm using a Tiny11 AVR (25c each), BTW, rather than a PIC. PICs are too expensive. Leon Leon
