For this week, we were finally introduced to serial communications. With the help of a P. Comp. session, we used the p5.serialcontrol app to read different values from a potentiometer and a button. The p5.serialcontrol app acts like the serial monitor on the Arduino IDE you can read the values in ascii or binary, but you can’t have both monitors open at the same time. Some notes to keep in mind:
When connecting a switch button always connect the resistor to one side of the button to the Arduino pin to the ground!! and for the other switch pin (SAME SIDE)! connect it to the +ive side on the breadboard
The higher the baud rate, the faster the numbers come in in the serial monitor
There are 8 bits in a byte
9600 bits = 1200.
serial.print sends the data as ascii
serial.write sends data as binary
serial.readString = reads ascii
serial.read = reads binary
I also tried using p5 editor with the Arduino and followed every step. But, guess what?!!!? It doesn't work!! 😁😅😩
I always get this message when I press play:
Something went wrong with the serial port. undefined
After meeting with David, turns out what I was doing wrong is that I open the port on p5.serial monitor app. So note to self, make sure the p5 serial app is on but not actually opening the port itself!!
