Learn how to use Simulink to make an Arduino based blower fan that levitates a ping pong ball at a specified height. An ultrasonic sensor measures the height of the ball and a PID controller adjusts the fan speed to maintain the desired height.
Arduino Mega 7.4V Li-po Battery
IRLZ14 MOSFET 1k Ohm Resistor
Fan Blower USB A to B Cable
Ping Pong Ball Tube (3D Printed or Homemade)
Sharp Infrared Sensor GP2Y0A21YK (will need a 3 pin JST connector)
Good work , it works with me too , using Matlab 2017a , and Arduino Uno (not Arduino Mega) PWM pin9(Make sure you change it if you use arduino uno)
I used 220V to 12V transformer for the fan (12V2A blower) , and I couldn't find the sharp sensor , I used a 4 pins TCRT5000 Infrared Sensor module , MOSFET also same as yours , but a longer Plastic tube , so I had a problem with the sensor (0.5CM to 1.5CM) .
Anyway , good job and I hope my information are helpful too in case anyone cannot find the exact components
What version of Simulink was required? Control design or real time desktop?
Great work! Good utilization of the dashboard blocks in External mode with Arduino.
