Is 120mA more then 40mA?
is it [40mA] also valid for 3.3V pin and 5V pin ?
I have a vibration motor which is run with 2.5-3.5V, max current is 120 mA and motor resistor is 29 ± 6 ?.So I have a project which contains LCD, phototransistor, IR LED, some buttons, potantiometer and vibration motor. I dont have a idea about that arduino uno's electric current is enough for this project. I know that digital pin max. current is 40 mA, is it also valid for 3.3V pin and 5V pin ?Thanks.
So? He knows 120 is too much for an i/o pin, but is asking if it's too much for the power supply pins.
Max current is 150mA
I just want to connect arduino to adapter and use my device. Is it possible ?
The Arduino's a controller remember, not a power supply
Can capacitor use for strengthen the current ?
