I'm brand new at electronics, and brand new at Arduino. I know very little about eighter, so please bear over with me... :-) To top it of, this is my very first post here on Electronics.
I'm working as a frontend developer, and my first Arduino project is about controlling a slot car via a website.
I can turn an LED on and off, remotely from a website, and I have connected the slot car to the Arduino, like I connected the LED, but of course there isn't enough power to get it running very fast. I does run, but sloooow... :-) I used a digital multi meter and saw that there were only 2V in the tracks, compared to 14.8V when plugged in the wall.
With my very limited knowledge of electronics, I was wondering if I could plug the slot car into the normal power socket, and somehow control how much power that goes into the tracks with Arduino.
How do I do that? With a resistor? Or?
Thank you in advance.
