Who's at the door Hans and Matilda were fast asleep when they heard a knock at the door. He put on a robe and wandered over to the door. "Who is it", he asked, "The postman" replied the stranger. Hans peered through the spyhole and saw the cap o...
Yes I am an udergraduate Engineering student and have been busy with my pre-final year exams, which were keeping me barred to progress in this design challenge. I waited a long to tinker with my new kits and finally I can start now. I have planned on...
I want to control windows using arduino.I got Tinkerkit servo in competition kit.But I just found another good solution,I found a 10 RPM 12 V DC geared which has pretty nice torque.So,need to makedecision between this two.What are your suggestions?&n...
Hello friends I was trying to getting started with arduino yun.I was able go get it on my laptop's wi-fi.Then I tried to re-configure it using 192.168.240.1 because arduino.local was not working.After re-configuring it showed that arduino is bei...
Not that I can play an mp3 file, let's find a way to build a simple TTS speechAs we live in a connected world, why not leveraging the power out there on the web to overtake hardware limitations? I found an interesting site herehttp://tts-api.com...
After finishing the data acquisition part of the project, let's see how to make the MagicHat a little more... magic To make Arduino Yun speak, I first need an external USB audio card like this one here Then, I need to install an m...
Hans also found the "pretty-wifi-info.lua" script for checking the Yún's WiFi status, it nicely abstracted Hans code from the hardware so he wrote a wrapper for that rather than writing his own. He used the "parse" module to i...
No electronics in today's post. Just a few pictures of the work on the sub-chassis.I'm avoiding to drill holes in the nice turntable coffer. I'm crafting a light carton base that nicely fits inside the turntable.The material I use is from my so...
This is my first SAMA5D4 firmware that takes a reasonable sample of audio range signals.I'm using the ADC buffer mechanism. The converter fills the buffer in the background.I'm reading the values and log them. Later I'll use them to drive the light o...
Good morning Ricksville One morning Farmer Hogg woke up, looked out the window and checked the colour of his field.He headed down to the kitchen and turned on his internet radio, Rick Astley was playing so he turned it off again.Old Mother Hubba...
So this weekend the genie buckled down, determined to finish the project he had started. His heart was delighted to see that he had finally finished all the wiring to his house! Now all that need to be done was furnishing and some aesthetics!#include...
I'm now at the point in the project where I can match what I have with what I can. I overestimated my skills when I announced that I would try to integrate a Shazam-like service into my player.Or more honest: I didn't overestimate. I set t...
The week was full of rain and clouds for the poor genie all week. Unable to leave his house and make any progress on the things that needed to get done, due to the unfortunate consequences of doing your electrical work in the rain, but today the sun ...
Just spotted this, it's the Yún but in a smaller form factor. http://arduino.org/products/arduino-yun-miniAlso spotted it's by the Arduino.org team not the Arduino.cc team if you care about such things.
I finally succeeded in measuring blood pressure in an almost reliable way. In this post I will show the results of my experiments In order to determine the law between the value returned by the Force Sensor Resistor and the blood pressure, I run...
Putting the Arduino Yun to sleep
Hans and Matilda thought back to the Golem and how he slept between each activity, that could also work for their Yún.
The key things were:
Turning the Linino power off
Turning the L...
I'm trying the Buffer and Hardware Trigger capabilities of the SAMA5D4.I followed the instructions on IioAdcDriver < Linux4SAM < TWiki, but was struggling with one particular command.I raised a topic on tha at91.com forum. And resolve...
I've mastered the SAMA5D4 just in time for chapter 3 closure. The end of a chapter is the right time to look back and reflect. The world is unfair for people that don't know. I have this powerful board in my hands. And I can't get anything...
Now that I have my SAMA5D4 development chain under control, it's time to do something with it.My first attempt is to move the Genuino sketch made for my light organ to the SAMA5D4.The design has 4 main steps: sampling, applying a Hamming window...
C.Defeo's Decorating and Building Merchants Hans and Matilda wanted some sheet metal to build the battery box so popped down to C.Defeo's Decorating and Building Merchants for supplies. The shop keeper advised them that he only had large sheets ...
I held off my review for more than a month.I have read the specs and was quite impressed.Then I reviewed the SAMA5D4 Xplained Ultra Evaluation Kit USER GUIDE. And I had mixed feelings after that.Hardware wise, this is a great document. Software wise,...
I'm making steady progress on this drizzly day.I have my first C++ linux program running that samples the an ADC pin on the SAMA4D4 Xplained Ultra Board. In the mid 90's, I was a C++ software developer. Around that same time, the standar...
