I interned at IIT Bombay in 2015 from 3rd July to 4th August. During my time over there, we were responsible for working on a cost-effective replacement for Arduino. The goal of this project was to work on a working prototype called Anudunio. (https://github.com/androportal/anuduino)

Arduino's cost around that time was about Rs. 800 ($12), and the cost for the Anuduino was Rs.100 ($1.5). Anuduino would contain basic features of the Arduino and would help in making workshops for the Arduino much more easier. We can not only save cost through this, but also ensure we have more participants since the main cause for missing the events is budget. 

I was responsible for problem-solving cost effective solutions and help test a few features.
