I am new to robotics. I want to make a robot using Arduino Uno R3. I need to use Gear Motor 9 for that here is the link.
The problem is that motor needs 50mA current. But arduino only outputs only 40mA current.
I want to supply the motors with another power source and use a switch to connect both the circuits. Can you please tell me what type of switch I can use.
Thanks in Advance. P.S. Sorry if I used any wrong technical terms
