Recitation 10: Media Controller

1. I connect the circuit according to the potentiometer example, and I also finish the code by using the example.
2. The things that I learned are that I reviewed how to use float and serial records, and I also learned how to connect the speed of the video.
3. I think my failure is that it takes me a long time to finish this project, it should be faster because this project is not that difficult. I think the thing I succeed in is that my potentiometer controls the image very well.

 

Arduino code:

/*
SendMultipleValues

Reads an analog input on pin 0, and sends a record that contains two values:

1. Value of `millis()`, modulo 1024.
2. The analog value that is read from pin 0.

If you attach a potentiometer to pin 0, you can control this value by moving
the pot.

This sketch pairs well with the RecieveMultipleValues example from the
Processing SerialRecord library
<https://osteele.github.io/Processing_SerialRecord/>.

Things to try:
– Connect a second potentiometer to the Arduino, and send the values from both
potentiometers, instead of send a value that is based on `millis()`.
– Send the value from another sensor, such as temperature or proximity.

#include “SerialRecord.h”

// Change this number to send a different number of values
SerialRecord writer(1);

void setup() {
Serial.begin(9600);
}

void loop() {
int sensorValue = analogRead(A0);

writer[0] = sensorValue;
//writer[1] = sensorValue;
writer.send();

// This delay slows down the loop, so that it runs less frequently. This can
// make it easier to debug the sketch, because new values are printed at a
// slower rate.
delay(10);
