e-Paper displays have a number of unique features, such as being visible in broad daylight, consuming very little current, and retaining their image when powered down. But they also have some disadvantages – they have poor refresh rates, limited color capability, and are more expensive than other display types.
in some applications, however, e-Paper is a perfect choice, and today we will see how to use these displays with both an Arduino and Raspberry Pi.
Today we will look at a powerful yet inexpensive machine vision sensor, the HuskyLens.
This amazing little device is based upon the powerful Kendryte K210 processor and is capable of adding machine vision capabilities to your projects.

The JSN-SR04T and A02YYUW are a couple of inexpensive waterproof ultrasonic distance sensors. They are easy to use, and have several advantages over the popular HC-SR04 sensor.
In this article I’ll show you how they work and how to use them with an Arduino Uno.
Learn to use common GPS positioning modules in your Arduino and Raspberry Pi projects.
Today we will see how satellite positioning systems work, and how to use GPS modules in our projects.
We’ll also build a GPS Logger to track our movements, then display our data on Google Maps.
CircuitPython is an easy-to-use language with hundreds of libraries for microcontrollers. Today we will be using CircuitPython with the Raspberry Pi Pico
With over 300 libraries already to go CircuitPython makes it easy to expose the power of the Raspberry Pi Pico.
Today we’ll see how to install CircuitPython and how to use it to build a keyboard emulator, a mouse emulator, work with MicroSD cards and flash some addressable RGB lights.
Today we will look at a few different ways to drive a servo motor with an ESP32 microcontroller.
We’ll be using a replacement for the Arduino Servo Library and recompiling classic Arduino servo sketches to work with the ESP32.
We will also drive multiple servos with a PCA9685 PWM module and build a web-based servo motor control.
The built-in CSI camera connector is one of the great features of the Raspberry Pi. Adding video capabilities can really bring your project up to the next level.
Today we will take a detailed look at the Raspberry Pi Camera. We’ll see how it works, how to use it and we’ll compare different models to see which one looks best.
The ESP32 is an inexpensive yet super-powerful 32-bit microcontroller that is loaded with advanced features. With built-in WiFi and Bluetooth BLE, the ESP32 can be the brains of your next Sensor, Robotics, or IoT project!
The DB1 project hasn’t moved forward much since we last got together, and there are some reasons for that. Today I’ll bring you up to speed on what’s happening, and how I plan to move forward
Don’t worry, DB1 is still very much alive! But in order to move forward, I’m making some changes to the publishing schedule.
I will also give you access to the first piece of “official” DB1 documentation, the I/O Distribution Board.
