One of my acquaintances pinged me today asking for suggestions/ideas for his Engineering project themed around IoT. At first, I gave my standard reply:
And at that instance, it hit me to get ideas from use-cases provided by leading IoT Companies such as the Kaa Project (http://www.kaaproject.org/) and many others.
I’ve compiled below a list of IoT Project Ideas for your Engineering Projects or IoT use-case demos and have listed them below with links back to the source. You can use these as a starting point and generate your own use cases or directly implement one of these. I’ll try adding in more use cases from other vendors. Happy Making (instead of ready-made buying :P). Ohh, it’s Engineer’s Day today. Happy that.
We often come across projects where we’d like to quickly hook up a sensor or an actuator that works on 5V to an Arduino (Uno and others) without using a breadboard. Since the Uno has only one 5V Pin, an easy way to get additional pairs of VCC+GND is to use the ICSP headers available for the Atmega328 and Atmega16U2.
One cool thing/feature I learned from the Arduino Uno WiFi board was how to implement/add an extra hardware Serial Port to the existing MCU using a I2C to Serial Bridge.
The Atmega328P MCU on the Arduino Uno has only one Hardware Serial port. If we’re interfacing a Serial Device to this MCU and would also like to use Serial debugging, an option is to use SoftwareSerial (which comes with it’s own set of issues and limitations). A better option is to have an I2C – Serial Bridge that’d allow the host MCU to interface with another Serial Device.
The Arduino.org team did this splendidly and used this SC16IS750IBS to have the MCU talk with the on-board ESP8266 through this I2C to Serial Bridge.
I’ll wait till someone builds a wrapper/library around it.
I’ve been thinking of using the Arduino MKR1000 instead with the AWS IoT. Let’s hope this get’s done quick 🙂
Pre.Scriptum: (Edit: 21, Dec, 2015) Amazon released the AWS IoT suite of applications and services a while back and I now feel it’ll be more helpful if we base our tutorial on the AWS IoT platform. It’s a TODO for me and hopefully I’ll have something up and running.
Cool things are getting revealed as days progress and folks crank out every single byte RAM from that mean power machine. Here we’ve come across an awesome project where a Pi is being used as an AVR programmer. I’m hoping this will be more handy and now make me not carry my heavy laptop.
