Background
The intent of this sketch is to spin a DC motor for five seconds and then stop. Then,
the motor will spin in the opposite direction for five seconds. The motor will operate
at half power. This behavior will continue until the Stop/Reset button is pressed.
Execute the Code
Before you can upload the sketch to the PULSE, remember to check your
connections. Keep in mind that you added a new connection with the motor. Plug
the end of the wire that extends from the DC motor into the DC Motor 1 port.
Upload the sketch. The green LED will light up, indicating that the code is ready
to execute. When this has happened, press the green Start button on the PULSE
controller.
Observe the direction and duration of the motor rotation. Did the motor’s behavior
match the intended program? Press the Stop/Reset button when you are ready to
stop the motor.
Further Investigate
The pulse Set Motor Power blocks allow you to adjust the percentage of power the
motor has. It can range from 0 (no power) to 100 (full power). If you wanted half
power, you would set the power to 50 (Figure 31).
Tip: What’s the difference
between a DC motor and a
servo motor? A DC motor
has two wires and can rotate
continuously. A TETRIX servo
motor has three wires and
can be placed into different
positions but can’t rotate
beyond 180 degrees.
