Remember that there is a limit on the amount of current that the PIC can supply. I limited my 2V LEDs to 0.8mA by using 3.8K Resistors. The total current usage is 20mA when all the LEDs are on. Assuming the 9V battery has a 400mAh life then this will give me at least 20 hours. Realistically I should get 30+ hours. |
