Need help with DC motor speed remote controller
Hi guys, i need helps with this stuff.
Before that i must say honestly that i don't have many experience in electronics. Yes i've learn some basics in schools but i'm not interested until now. Ok that's enough, let's move on.
I have a plan to make a DC motor speed controller (actually it is a remote controller). Actually it is a 3V toy car's motor.
I want the motor to run in simply two speed. But i don't know how can i remotely control it. I imagine that the controller only have one(or maybe two) button. So if we push the button, the motor will change it's speed (i.e. fast->slow, and otherwise). I suppose mayb i can use a tv remote or even a car door remote (if i not mistaken, both of it use infrared right?) to send the signal. But i have no idea how to do that, how can the car catch the signal, and how to process the signal.
So anyone can help me please?
Btw this forum is cool. I'm even more interested in electro after read the threads. Its like a silly lil kid who like firecracker come to a big firework festival lol.
