Attiny85 coin cell

ATtiny85 Ring Watch: Base on the previous Instructables - ATtiny Watch Core and more, I have made a real gadget, an ATtiny85 Ring Watch.

While awaiting my ATtiny order, I used the time to research a little more about this new turn I took (with little foreknowledge save it should work). I also waded through the data sheet for the ATTiny family to find out more of their capabilities. You can find the information here. There is a method to control more than 1 LED pre pin.

A coin cell (also known as a button cell) is a small round cylindrical battery. They consist of a single cell and are typically 5-20mm in diameter but often only a few millimetres thick therefore having a similar profile to a coin or button.

Mar 20, 2017 · The coin cell has high resistance, while the AAs, especially rechargeables, can supply amperes of current, and will easily exceed the 20 mA current limit of the diode, and quite possibly exceed the 40 mA limit for the AVR IO pin.
Oct 21, 2015 · Our ATtiny runs happily from a 3v coin cell and because we are driving our 12 LEDs in pulsed mode the overall current draw is quite low. We can therefore run our complete setup from a CR2032 coin cell for several days continuously. I haven’t tested it to exhaustion but I have run it for 48 hours continuously without any problems. The Standalone Voltage Logger has been merged with the Standalone Temperature Logger to give the Standalone Temperature/Voltage Logger available in kit form.. A standalone voltage logger in a small compact form factor with minimal parts using the ATtiny85 and powered by a 3V coin cell.
