I just picked up a IRF510 MOSFET from Radio Shack in my out of town trip this yesterday (closest radio shacks are about 45min-1 hour away). After I got home, i went to test it out. My question is, should i be able to test out the source-drain with just the +5V from my arduino (+ resistor + LED), or do I need to have a higher power source?
the way I hooked it up to test was like this...
Arduino Pin 7 to Gate, with 10K resistor pulling to ground. Arduino 5V to Source 1K resistor from Drain to LED, and LED to ground
in that configuration, no matter if Pin 7 is HIGH or LOW, the LED stays on
