This is a quick tutorial for our 128x64 and 128x32 pixel monochrome OLED displays. These displays are small, only about 1" diameter, but very readable due to the high contrast of an OLED display. Each OLED display is made of 128x64 or 128x32 individual white OLEDs, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!
Mu is an amazing editor that works with CircuitPython and compatible boards. You can connect to the serial REPL right inside the editor. It also includes a plotter the works with your code to give you a live visual graph of your data! This guide will show you different ways to use the plotter with different sensors. It's time to plot!
We carry a few different GPS modules here in the Adafruit shop, but none that satisfied our every desire - that's why we designed this little GPS breakout board. We believe this is the Ultimate GPS module, so we named it that. It's got everything you want and more. This guide will teach you how to wire it up to a computer or an Arduino, and how to use it.
This project uses the Feather M0 Express, the Adalogger Featherwing and the AM2320 Temperature and Humidity sensor to gather data from the sensor and save it to the SD card on the Adalogger. You'll learn how to record data, and then take that data, import it into a spreadsheet and turn it into an awesome graph!
The DSP-G1 is a digital synthesizer chip modeled after an analog synth, that has three oscillators per voice, a +24dB filter, two ADSR envelope generators, LFO, and more, for a great, paraphonic, five-voice 80s synth sound! Control it using MIDI note messages with a Trellis or two for input, and six knobs to send MIDI CC parameters to the synth.
Are you ready? Really ready? Cause here comes the fastest, most powerful Metro ever. The Adafruit Metro M4 featuring the Microchip ATSAMD51. This Metro is like a bullet train, with it's 120MHz Cortex M4 with floating point support. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset.
New from the fine people who have brought us the Beagle Board, we now have a smaller, lighter, but powerful single board linux computer, Beagle Bone! We like this move to a more compact and integrated SBC. For example, there is onboard Ethernet and USB host, as well as a USB client interface (a FTDI chip for shell access). It even comes preloaded with Angstrom Linux on the 4 GB microSD card! Here are some tips and tricks to get your BeagleBone up and running.
