If you step on the brakes, the car has a negative acceleration. If you drive in a car and step on the gas, the car has a positive acceleration. Doubles as the SCLK pin for SPI.Īcceleration is the rate of increase or decrease of velocity: Doubles as the MOSI pin for SPI communication. Doubles as the MISO pin for SPI communication. CS – Chip select pin for SPI communication.This pin is where the 3.3 volt power source would connect. 3V3 – The ADX元45 can be powered with 3.3 volts or 5 volts.Vin – Connects to a 5 volt power source.In this article we will use I2C, but SPI is an option if you want to use it. The ADX元45 can communicate with the Arduino over SPI and I2C. The z axis extends up and down, perpendicular to the x and y axes. The directional arrows indicate the direction of each sensor axis (x, y, and z) in relation to the physical board. The accelerometer we will use in this tutorial is the ADX元45 accelerometer from Adafruit: It includes all of the parts, wiring diagrams, code, and step-by-step instructions for 58 different robotics and internet of things projects that are super fun to build! Introduction to the ADX元45 Accelerometer The 3-in-1 Smart Car and IOT Learning Kit from SunFounder has everything you need to learn how to master the Arduino.
