The Hall Magnetic Sensor project showcases how to use an Arduino Nano to detect a magnetic field with a Hall sensor. This project will light up an LED when a magnetic field is detected. It is useful ...

Learn how to create a simple gear indicator for the manual transmission of the car. For that, we will use Arduino UNO with SSD1306 128x64px IIC OLED screen and 4 Hall Sensors to measure the magnetic ...

It is pretty easy to go to a big box store and get a digital speedometer for your bike. Not only is that no fun, but the little digital display isn’t going to win you any hacker cred. [AlexGyver] has ...

Abstract: This study aims to improve the safety and protection ability of electric bicycle riders, and designs and implements an intelligent anti-collision algorithm based on Arduino development board ...

One of the keys to efficient cycling performance is a consistent pedalling cadence. To achieve this the cyclist must always be in the correct gear, which can be tricky when your legs are burning and ...

Would you believe it, the ESP32 popular Wi-Fi and Bluetooth chip has a built-in Hall effect sensor. Espressif Systems makes the chip, and its ESP32 data sheet has nearly no mention of the Hall sensor ...
