4 Pin Ultrasonic Sensor Arduino Code

The mcu transmits ultrasonic waves through the trigger pin and then reads the receiving time of that ultrasonic wave on echo pin.

4 pin ultrasonic sensor arduino code.

It is essential to add a hex file of arduino. Connect echo to digital pin 6 on your arduino board. Select the port i e com3 and choose your arduino board type i e arduino uno genuino then compile it to your arduino. Connect trigger to digital pin 7 on your arduino board.

Wenn der trig trigger pin ein high signal bekommt wird der sensor eine ultraschallwelle senden bis der trigger pin wieder auf low gesetzt wird. First you should make sure you setup the pins correctly in your code assuming you are using pin 13 as the echo pin and pin 12 as the trig pin. The velocity of the ultrasonic wave traveling is defined and accordingly the distance is measured. The ultrasonic sensor hc sr04 includes four pins.

To create a 3 pin setup gnd 5v and sig you have to connect both the trigger pin and the echo pin to the same digital pin on the arduino. Easy ultrasonic 4 pin sensor monitoring hc sr04. I added the 4 int s to the beginning of the code so you can changes. Modified arduino ping example to work with 4 pin hc sr04 ultrasonic sensor distance measuring module hc sr04 ino.

This can be handy if you have very few i o pins available or if you want to use a 3 pin ultrasonic sensor like the parallax ping. In the code the only thing you have to change is line 6 7 and define the same pin for both the trigpin and the echopin. Vcc pin needs to be connected to vcc 5v gnd pin needs to be connected to gnd 0v trig pin this pin receives the control signal pulse from arduino. Ultrasonic sensor hc sr04 with arduino code for ranging testc c write your code in arduino ide software save it.

Hello instructables i have had some trouble with my cheap ultrasonic sensor hc sr04 and today i found a really easy solution. The ultrasonic sensor has 4 pins out of which 2 pins are for power and the remaining 2 pins are for the trigger and echo. Der hc sr04 hat 4 pins vcc gnd für die spannungsversorgung und trig und echo für das senden und empfangen von ultraschallwellen. The ultrasonic sensor can t do the echolocation stuff on its own though so you will need to program it your self don t worry its not very difficult.
