Ratshack Steering Motor - No stepper
Received Electronic Compass & Wheel Encoder from SuperDroidRobots.com. Downloaded doc to construct and test.
Have accumulated quite a collection of sensors however still don’t have a working robot.
RatShack Car: Appears steering stepper motor may not be a stepper after all need to do some more tests today. If I can’t get it to work I’ll need to hack the steering with a servo motor instead. Also need to locate power transistor H-Bridge on original circuit board and use them for drive wheels.
Steering motor: determined 3 wires connected to a 5K Pot direction feedback. Still don’t know what the blue 6th is.
Used 10 ohm resistor to ck steering motor current draw @ 4.5 V .. worked out to about 150 ma .. stall at 200 ma. Now to determine how to drive it w/ Oopic board.
