There was a need for work to visually read the condition of the equipment and, if necessary, restart the cryocompressor remotely. At hand was Arduino UNO, a light sensor was purchased for it, so far 2 relays and 2 solenoids at 12 V (not the point). In the future, this business will be overgrown with sensors of temperature, humidity and pressure, but so far it is not ready-made.
The reason for writing the post is that there was very little information on the Internet on the capabilities of Processing 3, especially in the Russian-language part of it. I hope that some teapots like me will come in handy someday so as not to stupid like me over the past week.
The sketch for Arduino is as simple as three rubles: when certain values are received from the com port, the dunk sets the value on the pins and writes the answer to the com port, measures the illumination and also reports on it. In the future, it will be expanded.
Sketch Arduino:
#include <Wire.h> #include <BH1750.h> int val; BH1750 lightMeter; void setup() { Serial.begin(9600); lightMeter.begin(); Serial.println("Running..."); pinMode (7, OUTPUT); pinMode(6, OUTPUT); digitalWrite(7, HIGH); digitalWrite(6, HIGH); } void loop() { uint16_t lux = lightMeter.readLightLevel(); if (Serial.available()) { val = Serial.read(); if (val == '0') { digitalWrite(7, HIGH); digitalWrite(6, HIGH); Serial.println(" "); } if (val == '1') { digitalWrite(7, HIGH); digitalWrite(6, LOW); Serial.println(" 1 "); } if (val == '2') { digitalWrite(7, LOW); digitalWrite(6, HIGH); Serial.println(" 2"); } if (val == '3') { digitalWrite(7, LOW); digitalWrite(6, LOW); Serial.println(" "); } if (val == '4') { if (lux >= 800) { Serial.print("Light: "); Serial.print(lux); Serial.println(" lx "); } else { Serial.print("Light: "); Serial.print(lux); Serial.println(" lx !!!!!!!"); } } } }
I think this is a no brainer, but due to the fact that other people will use the functionality of my Pribluda in the future, I wanted to write a simple but understandable GUI. The choice fell on Processing, as I was previously familiar with the Arduino IDE, which, in turn, was built on the basis of Processing.
The applet uses the ControlP5 library to render controls.
Personally, I had problems with implementing and searching for information on the following things: 1) launching the second window from the application, 2) closing the 2nd window, but so that the main window continues to work, 3) for the sake of fun - setting pictures as a background and buttons, translucent buttons.
So, the Processing sketch:

The program I received:
Time
Two
I ask you not to kick much - my first project on Processing, I hope someone can figure it out with such simple things as it turned out. And if someone tells me how to optimize my g ... code - I will be glad.
