Introduction: Hall Effect Sensor on Arduino Using Fidget Spinner
In this project I am explaining about how hall effect sensor works measuring fidget spinner speed with arduino board.
A Hall effect sensor is a transducer that varies its output voltage in response to a magnetic field. Hall effect sensors are used for proximity switching, positioning, speed detection, and current sensing applications. ... In its simplest form, the sensor operates as an analog transducer, directly returning a voltage.
1. It measures the temperature and humidity
2.Measures a speed of a object.
Step 1: Components Required
1. Arduino uno with cable
2. Hall effect sensor(Range a-3144)
3.Resistor 220 k
4. Jumper wires (x 3)
6. Neodymium magnet
Step 2: Procedure&Circuit Diagram
First connect the 1st pin to 5V and resistor , middle pin to GND ,last pin to digital pin no. 2 and resistor. After connect to arduino and breadboard as shown in circuit diagram. After take fidget spinner and neodymium magnet. Attach a magnet to spinner(fidget spinner must be metal at 3 sides).
Step 3: Final Step
After complete the connections connect the arduino to PC using cable. Open arduino IDE on PC verify and upload the code to arduino. Take fidget spinner with magnet and spin it near&perpendicular to hall effect sensor It detects the magnet and shows output.To show output click on serial monitor it shows output like this.
