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 ...
TinkerCad Tutorial #1 Simple Arduino LED Blink               Hi. Today, we shall another simulation tool which we can use to simulate our Arduino project. The best thing about this software is that it is free and no installation is required. All is done through online. The software which we will look in to is TinkerCad Circuits.                ...
If (like me) you’re a relative newcomer to Arduino's integrated development environment (IDE) but not to programming, then the icons might surprise you!   The icons are targeted for beginners, but I cannot tell that the up-arrow means open, and the down-arrow means save! None of it is intuitive to me : ( However, I’m a lot more familiar with Eclipse IDE.. I wanted Eclipse style icons : )  (I appreciate that for newcomers to Eclipse, probably some of the icons there don ...
Arduino Home An Open-Source platform to create digital devices and interactive objects that sense and control physical devices. Arduino Tutorials Arduino Projects   In the comments below:  Let Us Know How You Would Use the MKR RGB, MKR ENV, and MKR Shield in Your Arduino Projects!  Submit a Project Proposal for an IoT: In the Cloud project and we'll send out a limited number of shields for projects that use them!  View tech specs and unboxing videos for the Arduino MKR RGB ...
Does anyone know how to convert arduino code to c/c++?   I have made a 4x4x4 LED cube, but I need to have the code in c/c++, not just arduino code.   If anyone knows of a converter or can link a site to easily learn c/c++ on an arduino, that would be greatly appreciated. Thanks!   -Dan ...
Hi, I want to introduce our ArduiTouch MKR touch screen set for the Arduino MKR family. This kit enables you to mount an Arduino MKR board + optional MKR shield together with an resistive touch screen on a wall. here are some pictures:   ...
Hi,   some years ago I've posted some picture of our Arduibox DIN rail enclosure for Ardunino UNO. Meanwhile we have changed this enclosure and the protoboard pcb inside. It's possible now to use the new version not only with the UNO but also with the Nano and Yun rev2. Here are some pictures about the new enclosure set:     ...
I found this example really detailed and thorough.   https://www.mathworks.com/help/supportpkg/arduino/examples/arduino-based-smart-watering-of-plants.html   Any thoughts on what other sensors can come in handy when one uses smart techniques in agricultural space? ...
                            Welcome to the final part of my sharethescare which follows on from my previous blogs, listed below. I hope you enjoy reading about the journey I've taken to make my animatronic pumpkin head and I'll be testing it it really has the ability to Share The Scare!

Every year I am called upon to make Halloween costumes and accessories for my grandchildren.  Not scary stuff but things that they are into at the time.  Well, maybe a little bit scary... The kids originally asked for Legend of Zelda but changed it at the last minute and I only had a bit over a week to build.  The new theme was Mario Brothers with a need to accommodate the youngest, still not a year old.  The main build was a Mario castle that he can ride in dressed as Mario ...
Problem We all have little kids in our homes and every parent want to make sure that their kids are safe whenever they go outside of their homes. At the same time we also have little kids in our homes or around us how are special or little enough so they cant remember home address or their way back to home if they accidentally leave home and go little far away. And its very tough situations for parents if they cant find their little/special(mentally unstable etc) kids. Also if kids are in any so ...

Following on from Peter the Pumpkin - pt2   Progressing the Eyes I've progressed over the week with the eyes Mk5 e.g. paper mache. However it did take several nights of adding additional layers before I considered them to be strong enough to break out of the silicone egg cup moulds....and then I added some more paper mache for good measure. I also coated the outside in thinned down wood filler, allowed to dry, sanded, repeated, primed, sanded, primed and then added a white gloss finish. I ...

Peter the Pumpkin - pt2

Posted by 14rhb Oct 14, 2018
The weekend has been spent trying to make Pete some eyes. I've never made animatronic eyes but have studied how makers often achieve them using servos and so I thought that would be my approach. This blog details my attempts to make some servo eyes.   Idea ONE - table tennis balls. They would be lightweight and could be illuminated. But they were also too small. I also realised at this point that they eye holes were not the same shape or size (and why would they be as Pete was made totally ...
