Thank you for your valuable feedback. I have updated the article based on your suggestions.

There are couple of notes on it.
Quote: The echo pin is the one that becomes high after it receives reflected waves.
Note: Actually the echo pin goes high as soon as ultrasound wave is sent and it goes low when it receives the reflected wave.

Also the code of interrupt function is not quite correct:
ISR(INT0_vect)
{
if(i == 1)
{
TCCR1B = 0;
pulse = TCNT1;
TCNT1 = 0;
i = 0;
}
if(i == 0)
{
TCCR1B |= 1< ]]> By: Mushfick https://electrosome.com/ultrasonic-distance-sensor-atmega32/#comments/7451 Tue, 18 Jun 2019 12:52:00 +0000 https://electrosome.com/?p=14348#comment-7451 Why did you divide the pulse value by 58? can you explain the calculation behind that declaration?
Thank You
