In order to externally power the engines I’ll use a 8-battery rechargeable pack that I bought long time ago for a led strip. This pack offers 1.2*8=9.6V and 2.3mAh when it’s totally charged. I welded a power jack plug to power Arduino, but it’ll be more helpful powering batteries, so I grabbed a male power […]

With the PN2222A transistor issue solved I was finally able to start programming, that was what I was looking for initially. I added one wheel to the engine and checked the voltage (4.54V max with a 1KOhm resistance). It’s really slow, this won’t move the whole car kit (500g). I followed the scheme from the […]

I almost abandoned the whole project in order to come back to my world of ones and zeros where EVERYTHING WORKS. It seems that my PN2222A transistors are from a rare manufacturer who is not respecting the datasheet because the emitter-base-collector has other order, but first things first. Right after having the car kit mounted, […]

This is my first big project with Arduino. After so many doubts regarding which version to buy: 2 wheels, 4 wheels or even not touching anything related to Arduino at all, I finally chose the 4 wheel kit because the 2 wheel kit seemed ugly to me xD. I needed a few days to realize […]
