Arduino Beginner Experiments: Arduino and Linear Hall Sensor

HELLO THERE!!!

       How are you,guys? I hope everyone is fine and in a good mood always. This week I wanted to share with you guys a simple experiment I did over the weekend. The objective of this week's experiment is to receive basic feedback from the linear hall sensor.


What is a Linear Hall Sensor?

  Basically a linear hall sensor is a magnetic module with a digital interface. The sensor also has a built in LED in it.The sensor can detect magnetic field, thus making it useful in many projects (magnetic door lock to name a few).


HARDWARE:
1.Arduino UNO ( you can use other Arduino)
2.Linear Hall Sensor



SOFTWARE:
1.Arduino IDE

CIRCUIT ASSEMBLY
Referring to the sensor image below:



SENSOR                     ARDUINO
G               ---------->  GND
+               -----------> 5V
D0            -----------> Digital pin 8 (any digital pin)



CODING THE ARDUINO

int led=13; //initializing led pin in digital pin 13(built in led)
int hals=8;// initializing hall sensor in digital pin 8


void setup() {
pinMode(led, OUTPUT);// defining led as OUTPUT
Serial.begin(9600);//serial communication at 9600 bps

}

void loop() {
 if (digitalRead(hals)== HIGH) // read the digital value sensor and if the sensor value is high
 {
  digitalWrite(led,HIGH); //turn on the led 
  Serial.println("HIGH");//print out "HIGH"
 }
  if (digitalRead(hals)== LOW)// read the digital value sensor and if the sensor value is high
 {
  digitalWrite(led,LOW);//turn of the led
  
 }
}



   Upload the code to arduino and test it!! Bring the magnet close to the sensor and see the response and feedback of the sensor. A demo video is shown below:






    Well, that's all from me guys, this week. I hope to see you guys next week and till then, HAPPY TINKERING!!!

Arduino and Multi Function Shield: Pots,LEDs and buzzers

HELLO THERE!!!!!    How are you guys? I hope everyone is fine and in good mood always. This week, I continue my tinkerings with the Multi Function Shield. In this experiment, I used the potentiometer in the shield to control the LEDs in the shield. Without further wasting time, let's jump in straight to the experiment!! HARDWARE 1.ARDUINO UNO  2.MULTI-FUNCTION SHIELD SOFTWARE: 1. ARDUINO IDE CIRCUIT ASSEMBLY    The circuit assembly is fairly simple. Just attach the multi function shield on top of Arduino properly. Please attach the shield properly as failure to do so would cause the shield  not to function as intended. CODING THE ARDUINO: Let's refer to the multi-function shield image below: Referring to the image of the shield, it can be seen that the potentiometer (blue object near buttons) is connected to pin A0 (analog 0)     int pot = A0; //declaring the pot ...

Mixing Color with RGB LED!!

HELLO THERE!!!     Hi everybody!! How are you guys? This week, I am going to share with you guys a fun experiment that I did during the weekends. The objective of this experiment is to use the RGB LED to output different colors. Without wasting further time, let's get into the experiment!! HARDWARE: 1.Arduino UNO 2. 3 Potentiometer 3. RGB LED ( I used the Keyes RGB LED) SOFTWARE: 1.Arduino IDE CIRCUIT ASSEMBLY:   By referring to the image below: The RGB LED has 4 pins, 1 GND, 1 pin each for the color red, green and blue. RGB LED                      ----------> ARDUINO  GND(- sign of the pin)                  GND R,G,B                                              Any Digital pin(I used pin 9,10 and 11) T...

Arduino and Keyes KY-017 Mercury Tilt Sensor

HELLO THERE!!!     How are you guys? I hope everyone is fine and good as always. I am back in tinkering after a few months of hiatus( busy stuff :) ). So, today i would like to share with you guys on KY-017, which is a Keyes Mercury Tilt Sensor. KY-017 Sensor KY-017      The picture above shows the KY-017 Sensor from Keyes. It has 3 pins, A ground, A vcc, and A signal pin. If you look closely, there is a mercury ball inside the bulb like object. The mercury ball acts like a switch for this sensor. KY-017 Working Procedure: 1. When the sensor is not tilted, the mercury ball will be at the bottom of the bulb. This will complete the circuit and turns on the LED of the sensor. The output that is sent through the signal pin will be LOW. 2.When the sensor is tilted, the mercury ball will be at the top of the bulb(near at the sharper end). This will complete break circuit and turns off the LED of the sensor. The output that is sent through t...
