Help to Build a Sensor with Arduino Pro 3V
I tried to build a first battery sensor with an Arduino Pro Mini 3V but feeding it with 2 1.5V batteries the sensor will not work !!
But do I need to use a Step Up Boost Module or do I just follow the directions on this page ???

depends on the sensors, some works with 3v some does not and they require boost converter. You will find everything in sensor datasheet.
No firm !! What does not work and Arduino Pro Mini at 3V.
Do not start with two 1.5V batteries.
To work it requires at least 3.3V
How do I do it to make it work with two 3v batteries?

arduino should work with 3v without any modifications, something other must be wrong.
Discovered the problem !! I fed through the "RAW" pin while feeding through the VCC
Ok is now working
