| *My mistake: used printing and reading Sensor value Code from class and connected the wires to adruino into the wrong places
| |
| *got noise and weird number readings
| |
| *but funny that it somehow worked with seeing differences in the numbers when putting the magnet closer to the sensor
| |
|
| |
|
|
| |
|
|
| |
|
| Next I followed the instructions from Magnetic Hall sensor, thats put up on this MediaWiki
| |
|
| |
|
| *int ledPin = 13; // choose the pin for the LED
| |
| *int inputPin = 3; // Connect sensor to input pin 3
| |
| *int val = 0; // variable for reading the pin status
| |
|
| |
| void setup() {
| |
| pinMode(ledPin, OUTPUT); // declare LED as output
| |
| pinMode(inputPin, INPUT); // declare push button as input
| |
| }
| |
|
| |
| void loop(){
| |
| val = digitalRead(inputPin); // read input value
| |
| if (val == HIGH) { // check if the input is HIGH
| |
| digitalWrite(ledPin, LOW); // turn LED OFF
| |
| } else {
| |
| digitalWrite(ledPin, HIGH); // turn LED ON
| |
| }
| |
| }

|
| *Code was written correctly
| | |
| *but nothing happend with the sensor (I hope I did not break it, while using the wrong code from before)
| | |
| *noticed that there is no need for numbers to show up, the LED on the Sensor should have loght on and off.
| | |
| *did not work
