I'm new to the Arduino (using the Leonardo). I am working with a heatplate that gets hot when you apply power to it.
When I use the 5V Vcc pin it works fine. But when I use the digital pins I don't get enough current.
Is there any easy way to increase the amps you can get from the digital pins?
Would somebody have a simple driver circuit?
Thanks for the answer. This is my setup. I don't know exactly how much current the plate needs to get a high temperature fast, but i'm guessing in the range of 0,5 A - 1 A.
So basically, I need to use the transistor as a switch and then use another power supply for the heatplate-thingy ?
