Help to Build a Sensor with Arduino Pro 3V
-
Hello!!
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 3.3VHow 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
