Step 1: Parts

1. 1 9volt battery

2. 1 9volt battery connector

3. 1 connector

Step 2: Soldering

Solder the connector to the 9v clip

Step 3: Finished Product

There is also a "Vin' port which can accept voltages it's on the power terminal block, it also goes through the regulator ;)
<p>last time I tried that it got warm</p>
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.<br><br>I wouldn't use more than 9volts and 500mA though.
Oops wrong person
Does anyone know how to save data from a sensor to a sd card with arduino
Will it run on 6volts?
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
<p>According to the website it can technically accept up to 20V, however the voltage regulator will run too hot if run over 12V.</p>
Just use a 6v lantern battery from a flash light
<p>I have found that a 9 volt battery only last about a day.</p><p>I have started including 'wall warts' in my designs from the start. This allows a more continuous power flow</p>
Yeah it is really helpful
<p>thanks i actually needed this</p>
