I have a little project which blinks a series of 10 LEDs and has a weight limit. I had planned to use a 3.7v cell phone battery but it is just too heavy. The operating voltage for the attiny85 is like 2.7-5v. Can I substitute a 3v lithium coin battery? Will this work, and if so, how long can I expect it to run? Essentially the circuit runs 4 LEDs constant, and then uses the outputs on the chip to blink a series of 3 pins (2 lights each) in a loop. Thanks in advance!
Pulse current (Maximum) : 15mA
I'm going to go with "highly unlikely".
Normal Capacity: 600mAh
If you do find a coin cell battery that brings your circuit to life you can expect less than...
600mAh / (4 * 20mA) = 7.5 hours
...total run time.
I only need about 30 minutes of run time, so maybe it would work....i guess i will just give it a shot and see.
