This special event celebrates the 3rd birthday of Project14 and the 15th birthday of Arduino with an Open Ended Arduino project competition that kicks off the day before Arduino Day on March 21st, 2020. The NanoRama project competition is a follow up to Arduino Day 2020: NanoRama: We're Giving Away Different Nano Boards for Projects that Use Them! We also launched an Arduino Fundamentals: Part I: Quiz where you can test your knowledge (or argue over) your knowledge of Arduino. We will also have a round ups of the last two Arduino project competitions to celebrate Arduino Day in what has turned into an annual tradition.
Arduino Round Ups:
Project14 | The Birthday Special: Arduino in Energy Harvesting Projects!

Energy Harvesting is one of the most important topic for sustainability. We have lot of connected devices > be it smart home devices, city monitoring devices, industry specific devices,etc. Almost all of them need a continuous source of power but for some of the major use cases of just monitoring the place and sending the data every 1 hour or 30 min the energy is wasted for the rest of the time. Solar Power is also one of the only "free" source of energy and its widespread adoption is happening. This member wanted to use solar panel with low frequency of sending data to never think of the weather station.
For Ex: Even when we are not using our smartphones to browse the internet, the time when its just connected wastes power.
So, he wanted to make a weather station for himself which he would never need to think about. With the current implementation he doesn't even need to look after the device. The goal was simple: Make a weather station that lasts long, really long....

"Another great little project harvesting power from natural resources so that it can carry on working delivering the information over extended periods of time." - Community Member Judge
In most cases, IoT sensors will outlast the life of a battery, leaving the designers with mostly 3 factors to consider:
- Reducing the amount of data that will be gathered by the sensor
- Finding a strategy to replace batteries
- Introducing an alternate source of power to increase the amount of time the sensor spends collecting/transmitting data
One technology that can help counter the issues above is Energy Harvesting, which is the process of capturing/scavenge energy from external sources (e.g., solar power, wind, vibration, thermal, kinetic) to later power small devices like wearables and wireless sensors.
With the help of Internet of Things (IoT) and energy harvesting devices, wireless communications can represent the ideal communication scenario to easily and reliably connect devices in a system by bringing network capability, data collection, and management with little human intervention.

"An excellent solar based, IoT sensor project. Great energy harvester development, forming a very usable IoT sensor platform. Great work!" - Community Member Judge
"A well detailed blog and demonstration of powering a small device with the combination of solar power and super capacitors. The build was superb quality with professional results." - Community Member Judge
"A useful and detailed project. It should be useful for those who want to learn/ start with 'Energy harvesting'." - Community Member Judge
"Solar Powered IoT with Cayenne, luislabmo. This one did stand out to me. The parts and steps were explained the best. The video clearly showed his results. Source code and schematics were included. He harvested energy and used it to do something useful (soil moisture). He made his own circuit board, with several options for using with different projects. It was all very impressive. For my own use in the future, I wrote down the part numbers, the use of supercaps really interested me." - Community Member Judge
"The project was well planned and executed with a customised board using SMT. The many phases was completed in a small time frame and video was complete." - Community Member Judge

Simple Solar Bot by snidhi
|Simple Solar Bot|
Simple Power Bot was conceived as a simple solar powered robot capable of harnessing energy from solar panels. Part of this project involved learning more about how an Arduino handled power consumption and whether it could get the voltage and current that it needed from solar power boards. What's really impressive, is the fact that this was snidhi 's first attempt working with solar energy, an undertaking that she was very enthusiastic about. If everything goes according to plan, the Simple Solar Bot would be able to self sustain its energy requirements and be smart enough to go into sleep mode to consume less energy when there was no activity. Adjustments were necessary throughout the process to nail down the right motors to use for the mechanical design. This project involves an Arduino NaNo
"This project should be first place. It followed the theme and was completed. Being the first solar project by snidhi made it even better. ...Very detailed steps on how this project was created. From schematics, video, images and text. It could be re-made by many with the information included. ...Many uploaded videos detailing the continued progress throughout the project. The final video submission proves that it works and has a lot of potential. ...The project was original and very well planned. ...This being S Nidhi's first time working with solar power made it more impressive. There were some issues that were overcome with a couple of changes. ...Feedback was positive and encouraging." - Community Member Feedback
