Controlling motor to affect rover movement direction
This post is to capture finding on 2 wheeled rover movement procedure. the rover is connected to Laptop via serial connection provided by Arduino micro controller which will be referred to as only Arduino. Command sent from laptop is interpreted by Arduino and sends appropriate signals to motor controller. The motor controller allows direction of the wheel rotation to be changed and supply power to the wheels both left and right. Arduino supplies 5 v to each wheels. And in the sense of direction of the wheels, its either in clockwise or anti clockwise. These can be achieved by changing the polarity of the terminals. When signal 1 is sent to these circuit, the wheel rotates clockwise and if signal 2 the wheel rotates anticlockwise. So, direction of a wheel rotation is controlled by a pair of signals. Since we have two wheels, left and right, each wheel rotation direction controlled by a pair of signal that comes from Arduino. This means we have 4 signals that comes into ...
