This guide will show you how to build a smart measuring cup which displays the volume of liquid in real time on a web page. No longer will you need to squint and guess while measuring liquids; the smart measuring cup’s web page clearly shows the measured volume, and even converts between units or tares measurements like a digital scale!
The brains behind the smart measuring cup are an Arduino Yun and an eTape liquid level sensor. The Yun is the perfect platform for this project because it can read sensor data with it’s ATmega microcontroller, and serve a web application (written in python and Flask) using it’s Linux-based processor. By following this guide you can even learn how to send sensor data to a web page for your own projects.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
