Intro to Asynchronous Serial Communications
A Serial Output Sketch
A had a bit of an issue starting this lab where my Arduino would not power on. It wasn’t the USB cable, and it would power on if I unplugged the Arduino from my breadboard, so it had to be something connected on the board. I unplugged everything trying to find the problem, turns out it was a bad pot. So I swapped it out for another and the Arduino turned on and I was able to move on with the labs.
Sending the Data in Many Formats
Formatting Multiple Serial Date: Punctuation
With two potentiometers.
With two potentiometers and a pushbutton.
Flow Control: Call and Response (Handshaking)
Serial Input to P5.js
Program P5 to List the Available Serial Ports
Reading a Sensor and Displaying the Results in P5
I had one small hiccup here where the port kept reading ‘undefined’. I was reading through my code to see if I had missed or misspelled anything when I noticed my port name was “/dev/cu.usbmodem143201” which is what it is in Arduino IDE, however in the p5.serialcontrol software it reads “/dev/tty.usbmodem143201”, so once I fixed the name it worked.
Adding A Serial Port Select Menu
Draw a Graph With the Sensor Values
Serial Output from P5.js
Controlling the Brightness of an LED with P5
Sending ASCII-Encoded Serial Data
Program P5.js to Control the LED
Adjusted the keyPressed function to turn the LED on or off when ‘H’ or ‘L’ is pressed on the keyboard.
