Code for Non-Contact Capacitive Electrocardiograms (group project for ECE 522, Spring 2018)

Scripts

• AT.ino: for configuring HC-05 Bluetooth module via AT commands
• rtbt.ino: for operating the Arduino Uno and HC-05
• bt_ecg.m: for collecting data from the Arduino Uno and analyzing it

Setup

• configure baud rate of HC-05
  • check AT.ino for pinouts
  • remove Vcc of HC-05 and hold down button
  • reconnect Vcc. HC-05 should blink slowly
  • upload AT.ino and open serial monitor
  • set monitor to 9600 baud and type "AT+UART=115200,1,0"
• check the rtbt.ino for pin configurations of Arduino
• disconnect TX/RX
• upload rtbt.ino
• reconnect TX/RX
• run bt_ecg.m
