==Objective==

The course will show you how to use “Processing” to control the speed of the DC motor.

==Equipment==
*'''[[Microduino-Core]]'''
*'''[[Microduino-FT232R]]'''

*Other Hardware Equipment
**A USB cable
**A box of jumpers
**A breadboard
**A DC motor
**A potentiometer
**A resistor of 2.2K Ω
**A diode
**A transistor NPN

==Schematic==

==Program==

Refer to MicroduinoDCMotorControl

ProcessingDCMotorControl

==Debugging==

Step 1：Build hardware environment in accord with the schematic, just like this:

Step 2：Here the code we need：

The code of the two ends (Processing and Microduino)

Microduino:

//Send output value to the motor after getting the serial data

if(Serial.available())//if serial is available
{
leitura=Serial.read();//read serial data
Serial.println(leitura);
vel=map(leitura,0,255,0,1023);//map
if(leitura>0)//run motor by leitura
{
analogWrite(motorPin,vel);
delay(1);
}
else//stop motor
{
analogWrite(motorPin,LOW);
}
}

Processing:

//List all the serial ports and get data of the first serial port
// List all the available serial ports in the output pane.
// You will need to choose the port that the Wiring board is
// connected to from this list. The first port in the list is
// port #0 and the third port in the list is port #2.
println(Serial.list());
// Open the port that the Wiring board is connected to (in this case #0)
// Make sure to open the port at the same speed Wiring is using (9600bps)
port = new Serial(this, Serial.list()[0], 9600);

//Draw and update
void draw()
{
background(0);
update(mouseX/10);
println(mouseX);
}

//Transmit the x-coordinate value of the mouse through the serial port and draw the current value on Processing
void update(int x)
{
port.write(x);
stroke(255);
line(mouseX, 0, mouseX, 160);
text (mouseX, mouseX, 180);
}

Step 3：Download the code and compile successfully. .

Step 4：Move your mouse around in “Processing” after the system goes well to see speed change of the motor.

==Result==

A simple speed indicator will be displayed on the screen. The speed of the motor will change along with the change of your mouse on the x-coordinate.
