Historically, getting files on to a microcontroller device was a fraught process. You might have found yourself placing image data manually into arrays in code, or perhaps repeatedly swapping SD cards in and out. For select Arduino boards, that’s no longer a problem – thanks to the new TinyUSB library from Adafruit (Youtube link, embedded below). The library is available on Github, and is compatible with SA ...

For my latest project, I am diving back into Verilog to create the hardware side of Consolite. For those who don't know, Consolite is the name I've given to my design of a tiny hobbyist game console and associated software toolchain. In my previous posts, I demoed a compiler that translates from a flavor of C to Consolite Assembly, an assembler that translates from Consolite Assembly to binary files, and an ...

ulibSD It’s a library for use SD cards in SPI mode with uControllers, entirely writtenin C. This library can work with SD cards and also has the possibility to emulate the behavior in a PC file (GNU/Linux) using the macro _M_IX86. It’s for debugging purposes. The data transfer is oriented to 512 byte size, remember this. Public methods ulibSD has four public methods: SD_Init: Initialization the SD card. SD_ ...

I always considered circuit boards like this something you bought, not something you made. Not any more. I actually helped to make the board in the picture above. And it was awesome fun. The board is designed to monitor the conductivity (and, possibly, contamination) of water in lakes and streams, with the wonderful feature that it fits through the mouth of a regular water bottle. It’s called Riffle and it ...

The goal of this project is to learn as much as possible about the Zsun WiFi card reader and run OpenWrt on it to turn it into an awesome wifi device. UPDATE 2017-09-12 Info about LEDE and USB gadget working UPDATE 2016-11-28 Adding some more info about the new PCB revision, thanks to Erik Dorner, who sent me his analysis a long time ago UPDATE 2016-04-23 The new PCB is missing a jumper on the RX serial lin ...

This project, builds on Wunderground weather forecast via the Internet. Specs: 1. 3 days weather forecast (Low&High temps, probably of precipitation, condition icons) 2. Current weather conditions (Current temp, feelslike temp, humidity, pressure) 3. Current wind directions & speed with analog gauge meter. 4. Indoor temperature with Dallas 18b20 Temperature sensor. 5. NTP time via Wunderground time ...

Story The main purpose of this project is to build a system based on chip ATMEGA328P, Arduino compatible, and interface it with a 2.2" QVGA TFT display using the library ILI9341. As an alternative to the self-build system you can use an Arduino Pro 3.3 V/ 8 MHz board or similar. This system works well and can be very useful for many applications, as data-loggers, graphic terminal, etc. A great advantage of ...

This project started as many of mine usually do, as a honey-do. We have compiled an extensive list of our book and movie collections on our computer at home, but my wife wanted to be able to scan the list from the video store (yes, we still go to the video store). So I created a hand held device that allows us to scroll through text files stored on an SD card. I have my video collection and science fiction ...

I used: an Arduino Uno a Parallax PIR Motion Sensor and a Seeed Studio SD Card Shield Arduino, shield, sd card, logging shield, storage, logger Check out This instructable on PIRs in case you didn't know what it is: http://www.instructables.com/id/PIR-Motion-Sensor-Tutorial/ Step 1: Connect your PIR Sensor Hook up the PIR Sensor Ground pin to Ground VCC pin to 5V OUT to A5 To better help you understand how ...

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontr ...

Disclosure: This project operates the ATmega328-P-PU outside the published ATmel specifications: According to ATmel, the 328P requires slightly over 3.3V to reliably start the oscillator at 16MHz and to otherwise perform acceptably.  Lab testing here at SofKinetics has shown that the 'board-duino' 328P-PU can withstand below freezing and above 130F temperatures and that the 16MHz crystal oscillator will sta ...

Ready-made SD card logging shields for the Arduino typically cost in the range of $15 - $25. This is quite reasonable, but we might save a couple of bucks if we make our own. Not to mention all the fun in building it. Forget about soldering wires to a bare SD card socket. It's just too much hassle, and for about the same price as a socket you can get a breakout board. The cheapest SD card breakout board see ...
