mesamune80 said:ya i am using a red and a green LED,so you what you mean is 680 and 330 .And check the voltage output whether it is enough or not if not replace 330 with 270R right?hope there is no problem after this.
ya one question here,what PIC programmer do all of you using?
i need a USB programmer now,and dunno which one to choose >_<"
Any recommendation?
hi,
No, you replace the 270R with a 330R, the higher value of the bottom resistor the greater the voltage will be at the junction of the two resistors.
Use Ohms law to calculate the voltages on the divider.
EDIT: I use PIC Start Plus.. with MPLAB
