A complete guide to using DC servo motors with microcontrollers like Arduino and ESP32.
Learn how servos work, how to code for them and get some troubleshooting tips.
DC Servo Motor Guide – With ESP32 & Arduino
Two Raspberry Pi AI Cameras
Today we wil look at two artificial intelligence cameras for the Raspberry Pi. We wil compare the Raspberry Pi AI Camera to the ArduCam PiNSIGHT camera.
We wil examine the features of both of these edge computing devices, and naturally we wil test them out.

ESP32 Boards Manager 3 – Updating Your Old Code
ESP32 Boards Manager 3 for the Arduino IDE offers a significant improvement over previous versions. But that improvement comes at a cost – a lot of older ESP32 code will no longer compile.
Today we wil examine the new features of Boards Manager 3 and see how to convert our older code.
Using Digital Potentiometers to build Unique Projects
Digital Potentiometers, or “DigiPots”, are exactly what you think they are – potentiometers whose wiper position is set using a digital signal instead of a mechanical shaft or slider.
Today we will see how to use Digital Potentiometers and we’ll build a couple of projects. We’ll build a remote-controlled audio volume system and a variable power supply whose output voltage can be set with a web-based interface.
USB-PD – Power for Your Projects
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.
Arduino Alvik Robot
Meet the Alvik, a tiny yet powerful robot from Arduino. Alvik may be small, but it packs some advanced sensors and can be programmed using MicroPython or C++.
Let’s take a close look at the Alvik and learn how to write code for it. We’ll also see how we can add servo motors and I2C devices to expand our robots capabilities.
Raspberry Pi Remote Access – 3 Methods
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 & BLE with ESP32
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.
Using a Multimeter
The multimeter is the most essential piece of test equipment you can own. It’s ability to measure current, voltage , resistance and many more parameters makes it indispensable for the technician or experimenter.
Today we will see how to use a multimeter to measure just about everything.
