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.

  • You can use a TT2148 power transistor-this can connect to arduino without a resistor and deal with high current.

  • Personally I'd prefer a MOSFET...

  • What model of MOSFET do you prefer to use?

  • That depends on many factors - current levels, switching speed and voltages, footprint, etc. I have many that I often choose between. One of my current common ones is the TSM2314CX

  • The TSM2314CX then. That depends on many factors-state the obvious!
