In November I offered to use an Arduino UNO as a reversing monitor. Arduino Uno THROWBACK THURSDAY Contest It's a simple concept Arduino Ultrasonic ping sensor NeoPixel LED's   You use the ping sensor to detect the distance and change the colour of the NeoPixel to show Green for safe, Orange for Warning and Red for Stop.   In Part 1 ( http://www.element14.com/community/groups/arduino/blog/2016/01/07/ultrasonic-reversing-monitor ) I made this comment :-   Part Two I'm still ...
DIY-Thermocam - An open-source, do-it-yourself thermal imager     The DIY-Thermocam is a do-it-yourself, low-cost thermographic camera based upon the famous Teensy 3.2 mikrocontroller. It uses a long-wave infrared sensor from FLIR to provide high quality thermal images.   The aim of this project is to offer a cheap, open-source thermal plattform for private persons, educational institutes or small companies. There are various applications like finding heat leaks in the insulation ...
In November I offered to use an Arduino UNO as a reversing monitor. Arduino Uno THROWBACK THURSDAY Contest It's a simple concept Arduino Ultrasonic ping sensor NeoPixel LED's   You use the ping sensor to detect the distance and change the colour of the NeoPixel to show Green for safe, Orange for Warning and Red for Stop. Simple enough .... a few lines of code and its' all sorted.     What about Safety? There are no safety issues, you just reverse until the light changes ...
I've been working on this Arduino project for a while. Mostly mechanical issues, but finally got a solid solution for my LEGO train track switch. I am also using IoT style messaging to emulate a distributed network of "things". It's a little overkill for a single track switch, but it helps to understand the bigger picture with these types of technologies. I plan on integrating this with a train schedule API so I can send the train down a path based on real-world data. I also have an OLED display ...
  This Lego Weather Station is an exercise in IoT concepts using an Arduino (Cactus Micro Rev2) which has a built-in ESP8266 WiFi module. It then sends the sensor data using MQTT to a Mosca MQTT broker. A Node-RED client subscribes to the data feed, stores it into a MongoDB and then visualizes it with a Google Chart. The blog article is more about the journey than just the destination . This is one of many cool projects in the Internet of Lego city, which examines all sorts of interesting ...
