Input Devices

For this week assigmnement we had to :

  • My group assignment was
  • My individual assignment ws

The group assignment for this week is to:

Development Board Design

This week we had to work with output devices. Like last week, you can extend the capabilities of your microcontroller to the real world. This time not only to observe but to interact with the real world.

Introduction

In this weekk, I started to explore Hall Effect sensor

According to Wikipedia:”A Hall effect sensor is a device that is used to measure the magnitude of a magnetic field. Its output voltage is directly proportional to the magnetic field strength through it.“

In my design, sensor is placed on a separated board that connects to the xiao Rp2040 microcontroller board with wires. This is because that the Hall Effect sensor can only detect the magnetic field that approaches from a certain direction. It will be much harder to adjust the direction if the sensor is on a large board with all other components, while the other components and wires themselve can generate magnetic fields.
