Cal,high,10.000To tell the Arduino that the current amount of Hydrogen Ions and Hydroxide Ions it is reading is equal to 7.00 pH, enter this into the top box of the serial monitor, then hit return:
Congratulations, your pH probe is now calibrated! Close the serial monitor and the Arduino IDE. You are now ready to move on to work with the pH Visualizer.
To install the probe, first install Node.js (Windows or Mac or Linux). Then download the repository at https://github.com/oliviamriley/node-arduino by clicking the green clone/download button and selecting "download zip." Extract it and go to this repo's directory in your terminal/console and type "
node node-arduino.js -v color-scale". You can also install node-arduino-visualizer globally (recommended) through npm with
npm install -g node-arduino then typing
node-arduino -v color-scale into console, which will run the visualizer. You can make a shell script or a .bat with that console command (if you're on windows) and make a desktop link to it.
