Work in progress, semi daily blog, will post something more detailed later.   Entry 1 Using the CANReceiver sketch that comes with the CAN library. Started off with the CAN shield fitted, power from USB, no other CAN devices fitted. As it is, appears to be no signs on life in my serial terminal program, I'm using HandiTerm.   Modified the example CANReceiver sketch to do figure out what was going on. Started by adding a touch of blink LED code to loop() This proved the code is run ...
Here is a link to video of project in action - https://www.mathworks.com/videos/how-to-control-a-robotic-arm-from-a-remote-location-using-iot-1538564659095.html .   Introduction  Something I really wanted to try was designing a robotic arm completely from scratch. There are many open-source designs available, but I thought it would be gratifying if I could design, build, and program one from nothing (and it was).   I will talk about both the design and programming phases. But I ...
Introduction  This is my idea to develop a smart device, using the Arduino MKR WAN 1300 Board, which will help make access to communal spaces smarter. The reason for this blog was to put forward a proposal for the "Build a Smarter World" contest.     Problem to be addressed  There has always been a dilemma on how to manage public amenities effectively. One the one hand, if amenities have open access and are not monitored then anti-social problems tend to arise. While on t ...
1. Overview 2. The Project Requirement 3. A Possible 'Solution' 4. Project Implementation 5. The Negative(s)   1. Overview This is my proposed idea for Element 14 Smarter World contest Build a Smarter World: Propose a Smart Device to Win a Pair of Arduino MKR (LoRa Connectivity) WAN 1300 Boards and MKR Relay Proto Shield!  using the Arduino MKR WAN 1300. I do hope none of my proposal seems condescending or insulting to anyone in their more senior years. 2. The Pr ...
Introduction This project is an extension of the mobile rover project in the Arduino Engineering Kit. I added the following features to change how one can control the rover – Instead of programmatically specifying a set of waypoints for the rover to travel, I control it using my android phone. The inspiration for this project came from remote controlled cars, hence the design – tilt phone forward and backward to control the drive and tilt the phone sideways to control the steerin ...
The new Arduino MKR series sets up a standard about form factor, function and performance for Arduino boards in the future. These new boards comes in a compact shape, with a powerful 32 bit Cortex M0 micocontroller Atmel SAM D21 and a charger function for LiPo accumulators. Furthermore Arduino offers in this series different types of MKR modules for different IoT wireless technologies. Besides the base model Arduino MKR Zero some further types with WiFi, WAN or GSM support are available:   ...
I'm working currently on a professional RS422/RS485 shield for the Arduino UNO (and compatible boards) and other SBC with Arduino style headers (like STM Nucleo) . I wasn't satisfied with the shields on the market. They are very simple and have some disadvantages. My shield comes with the following features:     - RS485 mode (half duplex)   - RS422 mode (full duplex)   - galvanic isolation between Arduino and connected RS485 bus   - free choice of TX-pin between pins ...
A bucket list item for me was getting a 3D video game published.  Although I have a ton of web apps in use where I have worked to eliminate paper forms and processes, its been since the 1990's that I published software globally.  But that was freely distributable on aminet.net for the amiga and after 22 years has only received 1500 downloads.  The 2nd version - much improved - only got 89!  Ouch.   Amazingly, Aminet.net still exists and looks the same!  Here's a tri ...
Machine learning does not have to be complicated models that cannot be deployed to MCUs, it could be a model-free learning algorithm. Here is a video of the final project in action.     The motorcycle balances for about 10 -15 seconds, but further training and changing the incentives of the reward function can train it to balance longer How It All Started Balancing an inverted pendulum is a ubiquitous example used in controls curricula, with lots of available solutions, using concept ...
Story Keeping valuables safe and locked away is important to everyone. While you can have a manual safe, why not build your own safe box and add some smarts to it? Using an Arduino, a servo, joystick and an LCD screen, you can make the electronics for a combination lock safe. An overview of the safe system: This diagram shows the flow of data for the safe. Sensorsa. A joystick that controls the digits displayed on LCD screen. b. Two push buttons that are used to enter and set a new pas ...
As it's Arduino Day tomorrow I thought I'd write a quick summary of all my Arduino projects over the years. Prior to using Arduino I had ventured into Microcontrollers using the PIC series of chips. However, these required assembly level language coding and my last project although it worked fine on the emulator could not be made to work in real life. This got me disheartened and I did not do any such projects for some years.   Electronic Rotary Table After a long break from electronics I g ...

Our favorite development board is now in its rebellious years, and having it’s Quinceañera ─ 15 years old! For the special day, I wanted to put together an intermediate project featuring the staple of birthdays, candles. I wanted digital candles that you could also blow out like their anal ...

Tired of looking over your shoulder in your cube? This project solves that problem in a quiet, simple way – with a motion sensor and some lights.    The project by sections: A Passive Infrared Sensor (PIR Sensor) is some old technology. It dates back to Herbert Berman in 1970! ...
  Just in time for Halloween and Fall, a pumpkin… But not just an ordinary pumpkin. This one will stand out of all the other pumpkins sitting on people's porches…. Just sitting there. This pumpkin is about to fly away. Yes, a UFO pumpkin with lights. Ideal for the front porch of a house you want to catch people's eye as they pass by. If Christmas lights and decorations weren’t enough, we are bringing the decorative house lights earlier into the season. Now you can annoy ...
