The pump is small, works with 3.3V, but consumes 0.1A so I decided to use a transistor. The one I have is BF547, an NPN type small transistor. It supports currents up to 100 mA. I measured the hfe (beta) of the transistor, and it is 370.

Often, when overloading a pin, the Arduino chip is fried. Even worse, a typical USB port can only supply 500 mA, so you could have fried your computer if using USB. You'll need a … WebIntroduction. There are 20 GPIO (General Purpose Input \ Output) pins on the standard Arduino Uno and the SparkFun Redboard. These pins are limited to driving no more than about 40 mA of current. For controlling things like motors, 40 mA is just not enough. A small hobby motor requires at least 100 - 200 mA to spin up. trillyke
