There is also a "Vin' port which can accept voltages it's on the power terminal block, it also goes through the regulator ;)

last time I tried that it got warm

Perhaps use a 9v battery, I can run mine for more than 4hours and I have tested the power regulator with an oscilloscope and an infrared thermometer probe and it looks fine.

I wouldn't use more than 9volts and 500mA though.

Oops wrong person

[Ian helms]

Does anyone know how to save data from a sensor to a sd card with arduino

[Ian helms]

Will it run on 6volts?

[Ian helms]

I think the arduino uno can except up to 12 volts but I wouldn't do it unless you new exactly how many volts it excepts

[Aliasmk]

According to the website it can technically accept up to 20V, however the voltage regulator will run too hot if run over 12V.

Just use a 6v lantern battery from a flash light

I have found that a 9 volt battery only last about a day.

I have started including 'wall warts' in my designs from the start. This allows a more continuous power flow

[Ian helms]

Yeah it is really helpful

thanks i actually needed this
