Week 8 (FYP2): Design connection motor driver to arduino and choose best wheels for trolley follower.

Objective for this week:  for this week design for motor drive, how many inputs and outputs needed to control the arduino and also controls motor movement system to run the trolley. This week also choose the right tires for use in the movement of the trolley.

1. The figure below shows the design for motor drive use PROTELL99SE.

In motor drive, use a 12 V or 9 V by the heavy load trolley, trolley follower but to use 12 V in order to move the trolley follower. By using two motor left and right and has been set to arduino distance and speed of the motor movement.

Motor drive will detect two signals from the arduino ultrasonic sensor signal of the left and right. based on the signal, the motor will move according to the distance and speed set assigned.

In arduino have code Writes an analog value (PWM wave) to a pin. Can be used to drive a motor at various speeds. After a call to analogWrite(), the pin will generate a steady square wave of the specified duty cycle until the next call to analogWrite() (or a call to digitalRead() or digitalWrite() on the same pin). The frequency of the PWM signal on most pins is approximately 490 Hz. On the Uno and similar boards, pins 5 and 6 have a frequency of approximately 980 Hz. Pins 3 and 11 on the Leonardo also run at 980 Hz
