I want to make a disc shooter that can be attached to the arm, and I want to add a control system to it, basically when the palm "blocks" the shot, the disc shooter will not fire. So I thought to connect this sensor to perform this operation, do you think it is correct? Does it suit my needs?
This sensor would work to detect when an object is within a certain distance. Please see our other Arduino tutorials linked in the description of this video.
Yes, this sensor uses ultrasonic sound and should not be affected by lighting conditions (with the caveat that the speed of sound depends on air temperature, so that can indirectly affect the readings, but the sensor will still work).
No, this sensor is not designed to detect underground objects. The ultrasonic waves will be reflected back and it will just measure the distance to the ground.
In your Automatic Braking project using Ultrasonic sensor, I have changed the PING))) sensor to HCSR04. But there's a line in the code saying distance = readUltrasonic(pingPin) Now how to change that👆
The program in that project uses a function to read the ultrasonic sensor instead of putting all of the code directly in the loop() function. So, you would need to change the function to use two pins instead of one. For example, the call to the function could be distance = readUltrasonic(trigPin, echoPin) and then the first line of the function would be long readUltrasonic(int pin1, int pin2). You would then change the code in the function to use pin1 (corresponding to trigPin) and pin2 (corresponding to echoPin). We're glad that you asked about this because I realized there is actually an error in the existing example program - the way it's written now, the readUltrasonic function should use the "pin" variable inside the function, not "pingPin." so for example the line pinMode(pingPin, OUTPUT); should be pinMode(pin, OUTPUT). Hope that helps! We will update the example code.
you might not have the wires connected correctly make sure 5v in vcc ground in ground and that you have trigpin and echopin connected to the correct pin on the arduino to make it match with the code
