Distance Sensor Project Build In this video lesson we create a portable distance measuring prototype, using an Arduino Uno R4 WiFi. This project incorporates a HC-SR04 Ultrasonic Sensor, a ‘Go’ button, and the SSD1306 OLED Display. The project is powered by the Sunfounder Breadboard power ban...
You can also move the second line of code to the ‘loop’ function so that it will be executed repeatedly and keep transmitting it. This is useful if you are monitoring something in real time such as voltage or a sensor reading.
Arduino library for the ACD10 CO2 sensor (I2C). Description Experimental This library is to use the Aosong ACD10 CO2 sensor. Besides CO2 concentration this sensor also provides a temperature reading. The CO2 concentration supported by the sensor has a range from 400 ~ 5000 ppm ±(50ppm + 5%...

I made a 3D model of the HC-SR04 ultrasonic sensor in case you need one when making your next project with it. You can download it in from the link below. You can find and download this3D model at Thangs. Here are the dimensions of the HC-SR04 sensor: ...
If a shield/hat is added then it will automatically be connected to the processor base board. If a Grove sensor is added, it can easily be edited to change the socket ID to correspond with your real hardware. In either case Visual Designer will check to make sure that pins are not used...
The device uses an arduino uno R4 Wifi, a BMP180 pressure sensor which is on the GY-87 module. For your convenience, we present the circuit diagram used below: Schematic for the Portable Arduino Altimeter This is the code for this project, for your convenience. Arduino 1 2 3 4 5 6 ...

In this case we’re setting the value to the text “Hello World says Neil”. You can change this text to whatever your like. In future projects, this text can be a sensor reading, or the state of a lamp, for example. Finally, you can start the service, and the advertising, so oth...
When an object is placed on the surface of this sensor, the changes in the crystal’s resonant frequency can be detected and used to determine its mass in a variety of experimental conditions (air, vacuum, liquid). However, most QCM technology is proprietary and pricey – at least US$3000...
