Hello everybody,
I'm new to electronics, but managed to build an intervalometer for my camera. I used an IR receiver and an Arduino board to decode the remote signal and made a set-up that sends this signal. I've also added a small LCD screen on which I can configure the interval and time. But now I want to make my project not dependant on the Arduino board, but a standalone box powered by batteries. I plan to use one of the ATtiny chips for this, which I'll program using the Arduino.
I have absolutely no clue what kind of powersupply I should use for this project. Should I try to match the needed supply voltages for all the components by adding up batteries, or is it better to use a 9 V battery with a voltage divider? Long battery life is a must have in this case!
Any help would be greatly appreciated!
