Hey guys,
Ive got a PIC16F819 here, which has 2 PWM ports, each is capable of sinking and sourcing 25mA. I need to connect multiple IR LEDs to both of these ports, as many as is possible, however each LED will draw atleast 15mA which means I can really only use one per port.
Is there a way, using a BJT transistor, that I can run multiple IR LEDs off the same port. Also, the PWM frequency is 38KHz so the transistor would have to be able to cope with this.
Thanks
Michael Belperio.
