What’s better than a table with wheels? A table that you can drive around! This tutorial will teach you how to build your very own Mini Robotic Table, a project that was conceived and designed by one of my students (she was 10 when we started). We built this table because, in the words of…
While it is a bit tricky for us non-magical humans to levitate objects with our minds, words, or wands, we can use technology to do (basically) the same things! This project uses two micro:bits, a few small electronic parts, and some everyday objects from around the house to create our very own magical wand….
Whenever your phone rings or you get a text message, radio waves carry that information, whether in the form of a voice or letters, across vast distances. Different forms of wireless communication use different types of radio waves, which are differentiated by their wavelength and frequency. Cellphone radio waves can travel far, but eventually they…
Intro Nearly all of our wireless communication is done using radio waves*, including phone calls, text messages, and WiFi. With its built-in radio transmitters and receivers, the Micro:Bit microcontroller makes it super easy to build all sorts of projects with radio communication. This particular project is a simple & quick way to send text messages…
