SainSmart Hall Effect Sensor Switch Magnetic Detector for Arduino UNO R3 Motor

Dear friends welcome back! This is Nick from educ8s.tv and today we are going to see how to use the very useful magnetic field sensor with Arduino. Without further delay, let’s get started! Today’s project is this: When I place a magnet close to the sensor, an LED lights up in order to inform us that it detected a magnetic field. It is a very easy project to build but very useful as well. The sensor that we are using is called a Hall Effect sensor, a sensor that it can detect the presence of a magnetic field. The sensor is very cheap, this module I got for Arduino costs around 1.5$ and you can find a link for it in the description of the video. The sensor is used in many devices that we use daily. It is used in your bicycle computer in order to calculate your speed, it can be found on every brushless motor, in many cell phones, in the fuel tank of your car, in security systems, computer
