Hey. I have a probleme making a robot work with my netduino, I know this is an Arduino forum, but as far as I understand, it's pretty much the same. I think you guys might know what is my problem...
So I ordered a DF Robot kit
and got some help to put it together.
I want to control the wheels with my netduino.
What I want to do is simple. Press the netduino's button, and start the 4 wheels in the same direction, full power.
When I try to make it run with one wheel pluged in my breadboard, it works, the wheel move.
But when I add a second wheel, nothing appens. It seems that I dont have enough power to make the wheels move.
The netduino is powered by a 9volt battery. When I press the button, the net duino let the big power source ( 5 AA batteries , as suggested in the kit) flow in the motors. (this is how I see it correct me if i'm wrong.) Here's a scheme that my friend made me back when I was playing around before I had this kit. ( note that I removed the resistor)
Basically, I'm doing the exact same thing with my df robot kit.
The motors negative wires are all lined up in the #5 pin of the 4n35 transistor.
The 4 positive wires are all lined up with the positive power source positive wire. (5 new AA batteries) I'm using the 4n35 transistor that came with my netduino kit I ordered.
I'm starting to realise that I will need a motor shield. Which one do you guys suggest ?
But before I go on and buy another thing, is there a way to get it working with my current setup ?
