How to increase current in Arduino uno? How to increase current in O/P port in Arduino uno ?
to make it 200mA How I can do this?
It can in proggraming add more current
Which sample way to increase current ?
To control 2 Dc motor which normally work with 3 AA battery 
Thanks
You add a transistor. Just like when you're controlling a relay, which needs more current that the Arduino can provide.
