Unit 2 - Motion

Unit 2 - Motion (2B and 2C material and links under construction) 

The purpose of these labs are to develop a compact Arduino Box with distance and acceleration sensors, which can monitor its motion and wirelessly transmit the data that it collects in real time. Then we apply it to study various linear motion. 
  • Lab 2A: Linear motion on an air track
  • Lab 2B: Bluetooth Arduino with ultrasound/distance sensor
  • Lab 2C: Bluetooth Arduino with 3-axis accelerometer

Pre-Lab 2A: Linear motion on an air track

​​In this pre-lab we will revise the concepts concerning motion of objects on inclined planes.
  • Pre-lab Assignment slides 
    • Due 2 hours prior to start of Lab 2A

Lab 2A: Linear motion on an air track

  • Lab Instructions
  • Assignment slides 
  • In-lab analysis Jupyter notebook​​

Pre-Lab 2B: Bluetooth Arduino with ultrasound/distance sensor

In this pre-lab we will be preparing for soldering and setting up our Arduino to use a WiFi chip. You will be watching this video and describing the soldering process in your own words. Soldering can be very dangerous if safety precautions are not taken, so especially note ​.
  • Pre-lab 2B Instructions
​You will need the following to complete the pre-lab
  • Wifi Library​
  • Soldering Guide​

Lab 2B Instructions: Bluetooth Arduino with ultrasound/distance sensor

  • Assignment slides
Arduino code:
  • WiFi Ultrasound Receiver Arduino Code
  • WiFi Ultrasound Transmitter Code

Pre-Lab 2C: Bluetooth Arduino with 3-axis accelerometer  


In this pre-lab we will gain a basic understanding of how the accelerometer works and learn about the calibration of the accelerometer. Fill out the following slides and upload them to GradeScope
  • Pre-lab slides

Lab 2C Instructions: Bluetooth Arduino with 3-axis accelerometer 

  • Assignment slides
Arduino code:
  • Wifi Ultrasound Accelerometer Transmitter code​
  • Wifi Ultrasound Accelerometer Receiver code

Reference slides

  • Reference slides 2A
  • Reference slides 2B
