Note that while the ACE-Box can be used for all the exercises, it is not required and only the individual components are needed.

Required hardware for this exercise:

• Supported Arduino Uno board
• H-bridge
• DC gearbox (50:1) 6V motor
• USB cable
• 9V battery
• 9V power jack
• 2 x male-male wires
• 2 x male-female wires
• 2 x male-copper wires
  

Set-up the hardware as shown and following these steps:

1. xxxx

The Simulink block diagram for the H-bridge algorithm design is given, with the logic used for controlling the 'forward' and 'reverse' motion of the DC motor. Please note
that to implement this in real-time on a physical system, the switches would
need to be external, or logic built into Simulink. Based on the electronic circuit set-up
provided above, the operation of the H-bridge polarity ‘control’ operates as
follows:

1. ClockwiseMotion

• Set IN1 to High
• Set IN2 to Low

2. CounterclockwiseMotion

• Set IN1 to Low
• Set IN2 to High

3. Stop Motion

• Set both IN1 and IN2 to Low
• Set both IN1 and IN2 to High

Once, set-up and operating withinSimulink, perform the following:

1. Changethe switches as detailed above and view the scopes to explore how the signals are changing
2. Asthe PWM has values between 0 and 255 (150 and 255 are initially given below),
   investigate changing the numbers within the gain blocks to alter the speed of
   the DC motor.
