Story

Story behind the project

I heared that a Japanese company released a "blood strip brooch" before, and you can wear different brooches according to different moods. When you wear a "blood tank is empty" brooch, it shows that you are in a very bad mood at the moment, and colleagues know that it is not suitable to communicate with them at this moment. The sensor can directly identify the mood and automatically change the state, more advanced than manually changing the "blood bar"!

Project Introduction-Functions, How to use

As a Gemini, my mood changes randomly. So I designed this mood monitor, by wearing a finger cover equipped with GSR sensor to monitor heart rate. When the heart rate is at a certain value, it means that the mood is happy and can be disturbed. When the heart rate is at another value, it means you are angry at the moment, so do not disturb.

Process and steps

1. Conceive an idea;2. Find the corresponding sensor;3. Change the code;4. Function Varification.

Mood Monitor

#include "TFT_eSPI.h"
#include "Seeed_FS.h" //Including SD card library
#include "RawImage.h"  //Including image processing library

TFT_eSPI tft;
const int GSR=A0;
int sensorValue=0;
int gsr_average=0;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);

  if (!SD.begin(SDCARD_SS_PIN, SDCARD_SPI)) {
    Serial.println("init failed");
  }
  //Initialise LCD screen
  tft.begin();
  tft.fillScreen(TFT_BLACK);
  tft.setRotation(3);
}

void loop() {
  // put your main code here, to run repeatedly:
  long sum=0;
  for(int i=0;i<10;i++)           //Average the 10 measurements to remove the glitch
      {
      sensorValue=analogRead(GSR);
      sum += sensorValue;
      delay(5);
      }
   gsr_average = sum/10;

   delay(500);
   if (gsr_average<100)
   {
      drawImage<uint8_t>("happy.bmp", 0, 0);
   }
   else
   {
      //tft.fillScreen(TFT_BLACK);
      drawImage<uint8_t>("angry.bmp", 0, 0);
   }
   Serial.println(gsr_average);
}
