Light up to your groove

Posted by alrms Jan 7, 2021
Hello,   It's actually my first time joining a contest here in Element14, let alone doing blogging as well.   So the title sounds like a disco thing but here me out. I plan to submit a project that gamifies your moves in a way that can bring about joy with your family during the holiday season. I plan to incorporate some sensors and LEDs that you can bring along and play with your family members. Hopefully it gets done before the due date of this competition.   Cheers, Al ...
This will be my final post for the Holiday Special 20 project.  I was able to accomplish much of what I had planned, but failed to get the Christmas music to play from the external flash memory on the QT Py.  I'll use this post to describe the problems that I had and to summarize the project.  And I'll do a demo video.   Here are a couple of pictures of the completed construction (front and top view) which show the addition of the audio amplifier and speaker:   SamdAud ...
In the previous post (links at bottom), I had used my Xiao Expansion board to play Christmas music stored on the SD card using the SamdAudio player.   I don't have an SD card on my QT Py ornament, but I did add a 2MB GD25Q16 external SPI flash chip to the QT Py.  The music file that I'm using, "we-wish-you-a-merry-christmas.wav", is 1.39MB - so it should fit in the flash memory.   I've previously used the SPI flash chip as external file storage for CircuitPython, so the interfac ...
For the final element of my QT Py Christmas ornament, I'd like to add the ability to play some Christmas music.   The SAMD21 has a single DAC output that I'll use to generate tones, but I'll also need to add an audio amplifier to drive a speaker and figure out how to access the external flash memory that I added to store the music files.   In this blog I'm going to cover adding the audio amplifier and generating the tones using the DAC.  I'll hopefully be able to get the music p ...

A Lego Christmas game

Submit an EntrySubmit an Entry  Back to homepage Project14 Home Monthly Themes Monthly Theme Poll   A project idea (and some dead ends) If there's one thing that my kids associate with Christmas, it's Lego! More so than turkey, mince pies or a tree - it's often all about Lego. They tend to get at least some Lego as a present and they're currently sti ...
I know what I was doing a few years ago (2014 I think) as I was reminded by Facebook. See below.     Here is Santa riding in on my mobile robot at the Raspberry Jam I organised, possibly Christmas 2014, distributing sweets to any passing youngsters and/or students. Sadly I never got to see Santa as whenever I was present he seemed to have left the room.   Can I count this as a contribution towards the Holiday Special 20? Perhaps I'll have to do something else as well. Pity I s ...

The SAMD21 processor that is used on the QT Py has a built in Peripheral Touch Controller (PTC) that can detect touch on external capacitive sensors.  The PTC has a mutual-capacitance mode to sense touch on an x-y matrix and a self-capacitance mode to detect touch on a single point (pin).   The QT Py is in the 32 pin package so there are 6 capacitive touch pins available in self-capacitance mode (A0-A3,A6,A7).   Here is the PTC Block Diagram from the SAMD21 spec Adafruit ...
Having an interest in music and liking synthesizer music I thought it would be fun to create an analog version.  My primary experience has been with digital designs and robotic controllers, but very little analog work. While there are many software solutions available, I wanted the satisfaction of turning knobs and building the synth from the ground up. So I created a series of PCBs that provide the basic components needed for music generation.  I have a sequencer board (working now an ...
I am an Electronics engineering student from India as my country is one of the largest agricultural country in the world so I want to make technology for farmers for advanced farming.       For this I used ESP8266 WiFi module, Soil moisture sensor, Water level sensor, Rain sensor, PIR sensor, IR sensor, Stepper motor and relay... These are my one of those components which will I use for development of IoT based Smart Farming System (Hydroponics)... I am just working o ...
