Introduction: Do It Yourself a Heart Beat Monitor With AVR
Guys,
I want to share my weekend project on creating a heartbeat monitor with AVR.
In this experiment I'm using ATMEGA128 and LM358 as the sensor amplifier,
Let's get started
Step 1: Some Components for This Project
1. ATMEGA128
2. LM358
3. Infrared photo transistor
4. LCD 16x2
5. USBASP debugger
Step 2: A Software Developed on Atmel Studio
Then continue on developing the software for it,
Here's the main code...
cli();
current_rps = rps;
sei();
if (minute==1)
{
lcd_cmd(0x01);
sprintf(rps_lcd,"%.3f",current_rps);
sprintf(rpm_lcd,"%.3f", current_rps * 60.0);
lcd_xy(0,0);
lcd_string("BPS = ");
lcd_string(rps_lcd);
lcd_xy(1,0);
lcd_string("BPM = ");
lcd_string(rpm_lcd);
}
Step 3: Enjoy It on Video...
Enjoy it on video...
