A follow up project with the Arduino MKR CAN Shield. In this post, I try to offload as much effort as possible to the CAN IC, and reduce the load on the Arduino microcontroller.   CAN Receive with Interrupts  The CAN controller, the Microchip MCP2515, has several features that handle traffic management in hardware. The first one I review here, the read interrupt, takes care that the controller doesn't have to check if data is arriving. Instead of looping and polling all the time ...
I'm trying out CAN communication with the Arduino MKR CAN Shield.   I have a CAN bus test setup in the lab, with two DIY CAN drivers. If all is OK, I should be able to write firmware and plug the Arduino CAN shield onto that BUS. It can then snoop the data - and in a second step, send packets.     Introducing Arduino's MKR CAN Shield  The Arduino MKR series is rather interesting. A number of small-sized controller boards and a set of useful shields that match that size ...
I thought I was finished with this road test, but the creative part of the brain refused to shut down. Here's my final throw at the [Christmas Wreath of Things] Internet of Holiday Lights - summary. This is my tribute to Radio Shack / Tandy. You pulled me into electronics. The imprint of my nose is probably still visible on the window of the shop that was once your store in Diest, Belgium. A big thank you, and Fan Forever!   The road test is closing down. I had already submi ...

XMAS is over  On January 6, we remove our Christmas tree and lights in Belgium. So it's also time for my Christmas Wreath of Things to switch off. But we still have our Secret IoT Service going on - and I want to enjoy that for a little longer.   So I switched over to a low profile design: an LCD that glows when one of my Secret IoT Service partners is alive, and shows the name of the last person that sent me an I'm alive message. In the picture below, it was peteroakes.     ...
The idea  I've been dragging my feet to enter this contest.  Working with light is not my forte. But The Internet of Holiday Lights RoadTest Plus has a creative component. And  that's what pulled me in. I was going to build an Electro Mechanical Xmas Wreath of Things!         This is the proposal I submitted:   Christmas Wreath of Things ...  my entry is an electro-mechanical wreath. ... The wreath is a combination of mechanics, electroni ...
Several of us are posting a 'secret' message to the eclipse broker. You can subscribe to our topics and share the Xmas Light of Things.   If you post your MQTT payload here, I'll add them to the list.   who payload fvan fvan jancumps jancumps peteroakes peteroakes mcb1 mcb1     MQTT broker info: host: iot.eclipse.org port: 1883 please post a keep-alive every minute QoS: 1 Topic: element14_IoT ...
The internet is supposed to be a forum for collaboration and sharing. And the Internet of Holiday Lights contest asks for creative use of Eclipse's IoT offering.   So the two Belgian guys (Frederick and me) decided to team up and use the internet as our platform to work together. We believe that having our two devices connected to each other - and make them change each other's behavior - ticks the creative use of the Eclipse IoT offering box in an inventive way . Our gizmos work in isola ...
My entry for the Internet of Holiday Lights is an electro-mechanical wreath. My first blog post was a brain dump of possibilities. In my second post I made a paper prototype. My third post was about getting the Arduino Yun up and running. In the fourth post I used the Linux part of the Yun to get at the current date and time. In the fifth post I scavenged a stepper motor from a flatbed scanner. In post six that motor was running. Post seven is covering the Infineon RGB LED shield. My post numbe ...

My entry for the Internet of Holiday Lights is an electro-mechanical wreath. I am now working on the software part of the 'advent state' logic.   In my design, there is a bottom layer (the wreath) with 4 lights that represent advent candles. They are always on. On top of that, I'm mounting a circle with holes (the 'light filter').  That filter can turn and is driven by a motor.     Depending on what week of the advent we are, one, two, three or all four of the candles hav ...

My third post was about getting the Arduino Yun up and running. In the fourth post I used the Linux part of the Yun to get at the current date and time. I have now found a stepper motor to drive my wreath's optical filter. The quest for a motor I have a few dc motors in my scrap parts box,and a small servo motor. ...
My entry for the Internet of Holiday Lights is an electro-mechanical wreath. My first blog post was a brain dump of possibilities. In my second post I made a paper prototype. My third post was about getting the Arduino Yun up and running. This time I'm making the Atmel and Linux part work together to get current date information. Because I'm changing the state of my gizmo based on the advent calendar, I need to know current date info. Getting the right time from Linux I've prepped m ...
