I have two motors, not brushless, that pull 7.5amps each at stall. I want to use them for tank style steering and drive. I have my inputsheild with joystick connected to Uno and can make a circle of LEDs. but i digress..
My reading leads me a few different motor sheilds/pcbs in the $40-$120 range. I really thought this could be done cheaper as a h-bridge chip like the L298n is only a few bucks at sparkfun. Unfortunatly the 1 or 2 amp rating wont cut it. So I found this: http://www.pololu.com/catalog/product/707/specs but it seems to use only PWM as input. I'm not comfortable with that yet so would like to stick with analog input. I understand 0-1023. http://www.pololu.com/catalog/product/777 does everything which may be nice for other things in the future but at $100 it stings. Then there is this: http://www.pololu.com/catalog/product/1376 it has a USB port to monitor and config wich actually seems like another step of complexity i dont want. but its cheaper.
I guess I could post links all day but what I'm really asking is what motor controller should I buy to simply control 2 motors and control speed and direction of each ;)
thanks for any help, im just getting into motors and servos.
