3 dni temu · By connecting an ultrasonic sensor to an Arduino board and writing a few lines of code, you can create a sophisticated distance-measuring system in no time. This section will walk you through the process of wiring the components together and writing the necessary code to interface with the ultrasonic sensor.
5 dni temu · If your sensor measures a distance of 15 and sends it on Serial, then what is actually sent are the numbers 49 (the ASCII code for '1') and then 53 (the ASCII code for '5'). Have a look at this great thread used by thousands to learn how to handle serial data on an Arduino.
3 dni temu · Using the PCF8575 with Arduino involves wiring up the sensor to your Arduino-compatible microcontroller, installing the Adafruit PCF8574 library (which supports the PCF8575 as well!) and running the provided example code.
4 dni temu · Using the PCA9546 I2C multiplexer with Arduino involves wiring up the I2C multiplexer to your Arduino-compatible microcontroller and running the provided example code. If you're curious why you'd need an I2C multiplexer, be sure to check out this guide that goes in depth on working with multiple copies of the same I2C device, which most likely ...
