This video explains I2C communication using the Wire library, addressing and code to enable the Photon to communicate with external devices.
This video explains the basic differences between SPI and I2C communication as well as the peripheral pins and code required to enable the Photon to send and receive data with external devices.
The wirelessly configurable Particle Photon uses an ARM Cortex M3 to control its general purpose I/O for use in a wide array of IoT projects.
This video describes in detail the Photon’s USB, regulated 9V or external 3.3V power input methods and the recommended companion circuitry to prevent damage due to over-voltage.
Although hardwire communication between Particle Photons is quick and easy, the Photon is also capable of radio control and monitoring using a WiFi connection and TCP protocol. This video discusses the setup and client class programming functions nee
Arduino development platforms do not have built in debugging firmware or hardware. This video demonstrates several methods to add debugging through simple coding of the hardware serial port or the general purpose I/O ports.
A Sparkfun EasyVR shield installed and configured on an Arduino development board allows the user to implement voice and speech recognition. This video steps through assembly, installation, IDE configuration and example code
that demonstrates the fea
Robin introduces a voice controlled passive infrared alarm system using the EasyVR shield, an Arduino Uno and a PIR module.
Robin introduces a DC fan control project using Pulse Width Modulation (PWM) output from GPIO pin on a Raspberry Pi and a few peripheral devices.
Robin introduces an IoT project that operates a small DC fan using a touch screen slider on a custom app and the Raspberry Pi 3.
Kyle has been pretty good this year (if you ignore his countless pranks around the Digi-Key office) and he’s asking the red-suited guy for the :move Mini Buggy Kit from Kitronik.
Robin gives us part 1 on how to use the GPIO C++ Library on the Raspberry Pi. In this video we will learn about the initial set up of a main.c file and how to use libraries for Raspberry Pi.
Ashley is asking for AdaBox kits this year for the holidays.
Ashley’s wants the Airblock and mBot Ranger from Makeblock for the Holidays.
Robin walks us through setting up an IoT controlled NeoPixel by way of a Micro:Bit, PC, and Adafruit IO.
Robin shows us how to use MQTT with an Arduino and an Ethernet Shield.
Robin gives us part 2 on how to use the GPIO C++ Library on the Raspberry Pi. In this video we will learn about Interrupts, Timing, and PWM signals.
Today Robin shows us how to use Adafruit IO and sending and receiving data from it. Robin walks us through the code and explains the function of each line.
In this how-to article, we will learn how to use the Circuit Playground Express with NeoPixel rings using Microsoft’s MakeCode editor!
