Hello!
I am working on a Fire fighting Robot(Using a Picaxe 28x1) and successfully completed the navigation test, after that I went on to work on the fan (A motor with a propeller) that would put out the fire, but I couldn't get it to work; after a little research online, I understood that I required a darlington to make fan work, I did NOT use a Darlington as I "replaced" it with a 330 ohm resistor array as I used a servo (which controls the movement of the neck that moves the Distance Sensor). That's when I came across Yellow Drum Machine(www.letsmakerobots.com/node/1050) and I noticed how Mr. Frits used a L293D to control the Motor which acts as a neck! I decided to implement this Idea in my Robot but it doesn't seem to work. I used the same Test Code that was Attached. I am unable to figure out what I have NOT done correctly. Can someone please help me out? Thank you! :)
PS If there is a way to use both the Servo and the Fan, please do let me know. Thank you!
