Bike speedometer using Arduino wth Hall effect sensor Bike speedometer using Arduino wth Hall effect sensor. Building an Arduino (Atmel AVG micro) based design would be fairly easy using magnets (on the wheels or axles) and reed switches for pickup, but optical pickups or Hall effect sensors would be more reliable. Hall sensors are used for proximity switching, positioning, speed detection, and current sensing applications. An up/down counter is used to register the magnets passing, while an Arduino Pro Mini reads this and outputs the proper signal to display the correct number via binary coded decimal (BCD) decoders. From here, you can infer the distance that your device has traveled, or any number of other important variables. In comparison to the Hall Effect sensor, a magnet (powered by a speedometer cable) is required to mechanically turn the reed switch on and off (approximately four times per one complete rotation of the magnet). I tested the software with a square wave signal of 5 V, but it shown a frequency that was twice of the input source (PWM) frequency from a signal generator. waveform relative to the speed of the motor. To monitor RPM, we need to have a feedback or sensor to sense shaft rotation.

I'm currently doing a project involving wirless speed control and speed monitoring devices using an Arduino ATMEGA644. We use the capacitor to decouple the power, to remove unwanted distortion or oscillations in the circuit because we have a common power supply powering both the GRBL arduino, as well as an arduino nano for this circuit. BRUH Automation 687,192 views. Some time we required to check the RPM of the motor while creating projects. Measuring Speed using Hall Sensor and Arduino: Before we get our hands on the hardware, let us know how we are actually going to measure the speed using Arduino. I attached the Hall Effect sensor to the right fork leg and epoxied a rare-earth magnet into a suitable bolt, which occupies one of the (unused) right-side disc rotor mounting holes: Magnet. I tested the software with a square wave signal of 5 V, but it shown a frequency that was twice of the input source (PWM) frequency from a signal generator. 3V devices), GND goes to GND, while the SDA and SCL pins are connected to pins A4 and A5 of the Arduino, respectively (Fig. I use a 47 ohms resistor on each.
