Introduction Let’s start at the beginning. What is an FPGA? Well, FPGA stands for Field Programmable Gate Array, which isn’t helpful in understanding what they are or do but we had to get that out of the way. FPGAs belong to a class of devices known as programmable logic, or sometimes referred to as programmable hardware. Essentially, an FPGA doesn’t do anything itself but it can be configured to
Note: This tutorial covers concepts or technologies that are no longer current. It's still here for you to read and enjoy, but may not be as useful as our newest tutorials. Note: Unfortunately, Google delisted us from the Google Play store because the app shown later in this tutorial no longer supports the latest and greatest cell phones. The source code is open source so we encourage anyone to pi
In addition to breaking out the switch contacts to breadboard-compatible headers, the breakout also provides access to an optional switch-mounted LED. Plus, the pin break-outs are designed with keyboard matrix-ing in mind, so you can interconnect as many boards as you'd like into a row-column configuration, keeping the I/O-pin requirements as low as possible. The Cherry MX Switch Breakout is a per
Introduction In this tutorial, we'll show you how to install FTDI drivers on multiple operating systems. Although this tutorial was written using Windows 7, Mac OS X 10.6, and Ubuntu 13.04, the process should be very similar, if not exactly the same, for other versions/variations of these operating systems. Suggested Reading Before you begin this tutorial, you should have the Arduino IDE installed
Introduction Do you have a 3.3V I2C or SPI sensor that might go up in smoke if connected to a 5V Arduino? Or a 5V device that needs a workaround to be compatible with your 3.3V Raspberry Pi 4, Raspberry Pi Zero, RedBoard Turbo, RedBoard Turbo or Arduino Due? To get over this obstacle you need a device that can shift 3.3V up to 5V or 5V down to 3.3V. This is called logic level shifting. Level shift
Heads up! Ubilinux is no longer maintained, although it can still be downloaded here. We also recommend checking out jubilinux as an alternative Debian distribution for the Edison. If you have been playing with the Edison, you might have noticed that the Yocto Project can be difficult to work with. Namely, they want you to re-build Linux from scratch every time you need to enable a package. This i
Heads up! This is for the Pro Micro (ATmega32U4) 5V and 3.3V versions. If you are looking for information about hardware on the Qwiic Pro Micro with the USB-C connector, make sure to check out the newer Qwiic Pro Micro USB-C (ATmega32U4) Hookup Guide. Welcome to the new frontier of Arduino-compatible boards, made possible by the ATmega32U4. No longer does your Arduino need to be harnessed by an FT
Introduction Here at SparkFun, we love gadgets and gizmos, just like our customers. And, like many of you, we find ourselves frustrated all too often by shallow reviews that focus on the "gee whiz!" factor of fancy new electronics without really taking the time to tear into the nitty gritty of how a device works. As the release of the Leap Motion draws nearer, we're all wondering, what does it do?
New! How to Run a 5V Device On a 3.3V System With Qwiic Power up your 5V I2C devices on the Qwiic system! This tutorial shows you how to use the SparkFun Qwiic 5V Boost to integrate power-hungry sensors like the SEN55 seamlessly.
Heads up! This tutorial was written originally written for the Arduino Pro Mini 3.3V/8MHz. However, you can still use this as a guide to upload code for Arduino Pro Mini 5V/16MHz. To upload adjust the Processor in the Arduino IDE when uploading code to the 5V version board. The original, true-blue Arduino is open-source hardware, which means anyone is free to download the design files and spin the
Introduction Awhile ago I read about Nest, a newfangled thermostat with a color display and some interesting 'learning' techniques for keeping your home warmed or cooled, as sensible as possible. Did I mention the beast has IR proximity, PIR movement, humidity, magneto scroll, and a mini USB connector? Oh. It does. It's kind of awesome, but it comes at a price. Pre-orders were $249 + shipping but
Introduction The IOIO-OTG (pronounced “yo-yo-O-T-G"; the OTG stands for On-The-Go) is a development board specially designed to allow developers to add advanced hardware I/O capabilities to their Android or PC application. It features a PIC microcontroller, which acts like a bridge that connects an app on your PC or Android device to low-level peripherals like GPIO, PWM, ADC, I2C, SPI and UART. An
