Hello. How to use one wire protocol in 2020 model hcsr04 modules?
hello
Please post the datasheet.
Are you impatient? You should wait 24 hours before kicking your topic; those that might know the answer might be sleeping.
Welcome! You don't, read the data sheet. My answer is based on this:
"The HC-SR04 ultrasonic sensor module interfaces with microcontrollers like Arduino using four pins: VCC, GND, Trig, and Echo. To measure distance, you send a 10µs pulse to the Trig pin, which triggers the sensor to emit ultrasonic waves, and then measure the time it takes for the echo to return on the Echo pin."
I was sleeping when you posted; my computer does not tell me somebody is impatient for an answer.
