Today we are looking at the new Arduino Uno Q, a unique board that contains both a microcomputer and microcontroller.
We wil take a look at this unique piece of hardware, then we wil learn about Apps, which are programs that use both Python and C++
Want to build n electronic compass or a guidance system for a robot? Adafruit’s LSM303AGR module is the perfect component for you.
Today we wil look at this versatile module and perform experiments with it. We wil also see how to calibrate it, and we wil indeed build a simple compass with an OLED display.
Come meet the XIAO family! Today we wil take a look at all of the members of the Seeeduino XIAO microcontroller family. And there are over a dozen of them!
We wil check out their specs and then create three very different projects that use the same circuit (but different XIAO boards).
Air Pressure is literally all around you! Today we wil be testing three inexpensive yet accurate air pressure sensors – the MS8607, BME280 and LPS25.
All of these sensors are on similar Adafruit modules. We will l try them out with a variety of microcontrollers, and we’ll code in C++ and MicroPython.
Learn to setup and use WLED, the amazing ESP32-based product for controlling every type of LED strip. We will see how WLED works, how to choose LED strip lights and how to safely wire everything up.
We wil also hookup a microphone and use Audio Reactive, to control our LEDs with sound.
Today we are working with the TMP117, a precision temperature sensor with an accuracy within 0.1 degrees Celsius.
We’ll see how this sensor, on a module from Adafruit, can be easily connected to a microcontroller to build a super-accurate thermometer. We’ll even put together a WiFi thermometer with an OLED display.
Non-volatile Storage is memory that keeps its data without power. Pretty useful for saving configuration settings and web data.
Today we will examine four types of non-removable NV Storage – Internal Flash, External EEPROM, SPI NOR Flash and FRAM. We’ll see how they work, what advantages (and disadvantages) they have and how to use them with an ESP32.
