Hi
I've checked the spec sheets, it says the led bacjk light typically uses 240ma. So I used a 18ohm resistor to supply 5V. It also said the lcd itself only uses max of 3ma. Can I still use the same supply or would I have limit to 3ma?
Also is there a calculation I can make to see how long will my battery last?
