Today we wil look at rapid prototyping systems, wiring systems that allow you to quickly hook up common electronic components, modules and microcontrollers.
We will take a look at three of the most popular systems – Qwiic, Grove and STEMMA. We’ll see how they work, and how they can speed up the development process and eliminate wiring errors
The Arduino App Lab is a utility specifically designed for creating “apps” for the Arduino Uno Q. The Arduino Uno Q is a unique board that combines a microcontroller and microcomputer. The App Lab lets you build apps using both C++ and Python.
Note that the App Lab is still a “work-in-progress”, so some feature are either non-existent or buggy. But it is still usable and I’ll show you how we can get around its many idiosyncrasies to create our own apps.
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.
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.

Looking for a power supply for your next project? How about one that can deliver up to 20 volt’s at 5 amps?
USB-PD is a technology that permits USB power supplies and chargers to deliver multiple voltages and currents. Today we wil learn how to use USB-PD in our projects.
Why use a mouse, keyboard and monitor with your Raspberry Pi when you don’t have to? Learn to enable and use Remote Access on the Raspberry Pi and control your little boards from anywhere in the world!
We wil examine three remote access methods you can use – SSH, VNC and Raspberry Pi Connect.
Bluetooth Classic and Bluetooth Low Energy (BLE) and short-range communications systems that connect computers, mobile devices, peripherals and sensors. You probably have several Bluetooth devices in your home, and with the ESP32 you can connect to all of them.
The ESP32 is Bluetooth-capable, but not every ESP32 wil work with every version of Bluetooth.
Join me today to learn all about Bluetooth and how to work with it on the ESP32.
