Getting started with Ultrasonic Sensor Arduino and Raspberry Pi Pairing Guide For this tutorial, we will be using theGrove Ultrasonic Distance Sensorand pair it with the Arduino and Raspberry Pi. For the first tutorial, we have the guide for Arduino. Scroll down for the tutorial on Raspberry Pi...
Serial.println("Clear sensor area. Then enter c again"); while (Serial.read() != 'c') { //do nothing ; } color(); cal_max_r = red; cal_max_g = green; cal_max_b = blue; Serial.println("Put white color infront of sensor, Then enter c again"); while (Serial.read() !=...
Adding a setup_sensor() function to main.cpp (or elsewhere). This setup function will add the sensor column names to the configuration message. The highest sample rate will be used when sending data out, regardless of if the sensor has an update. Adding an update_sensor() function to main...

In this tutorial, we will not try to control any large appliances for the sake of simplicity. We will stick to LEDs that you can connect directly to the Arduino. Just pretend that the LED is an appliance! The first step: Install The Arduino IDE:The Arduino IDE is an app that you can...
I have several interesting sensors in my hardware to-do pile, and I think it’d be interesting to do a series of interactive UIs one for each sensor. My first effort in this vein was a browser UI to interactively play with an AS7341 spectral color sensor, andI learned a lot doing it...

图1-6 Common parts: Raspberry Pi, Arduino Uno, ultrasonic sensor, battery holder, and breadboard你不需要对显示器和键盘着迷。一旦你阅读了第二章,在那里我们安装和配置了 Raspberry Pi,你不再需要它们了。我有几个无线键盘,因为我通常会同时进行几个项目。对于显示器,我只需使用一台带有 HDMI-DVI 适配器...
The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how the sensor works and how to use it with Arduino....
