The day started with Ms Maria from Reapbenefit asking us about the problems and good things about Bangalore. It took us about 6 minuets to list enough things. The bad things overwhelmed the good things. The good things had things like malls and roads, but malls and roads make bad things like pollution, traffic, trash etc. Later she said we were here to fix the trash part by coding and building smart bins. Akash was the only one familiar with this because he was part of something like this in another CL day.
We then got in pairs (or trios) and grouped up. Each group received a box with cool chips and boards of tech. It looked very complicated, because it was! The only thing I knew what to do is to plug the usb cable into the Arduino board. It had so many things but packed into one tiny board, it overwhelmed me. Ms. Maria didn’t want to call us by This group, that group, their group, and the other group. So we had group names and everything was simplified and totally easy. The groups were This group, that group, their group and S.A.S. SAS stood for Sooahn, Alli Sanaa. We took our Arduino board to the computer and plugged it in.
The instructors told us the basics of the code, like to verify your code and to upload your code. And then to the even more basic stuff, it was so hard and I couldn’t understand what to do. I asked Akash for help and he helped me. He tried his best to explain to me, but it was so hard. I could see the struggle on his face. After that we went to something harder, at this point I was scared. But it turned out it was easy. We learned to make the lights blink in different colors. And we also learned to show our names in Morse code. The bell rang and we went to snack.
When I saw my friends who weren’t in our group, I had a feeling that I haven’t seen them in weeks, but they felt normal so the coding probably got to my head. We went back to the class and everyone was their, except Alli and Sooahn. They came like 7 minuets later because Sooahn felt sick. She then went home early. Team SAS turned into team SA... or AS.
Now we were learning about the cords. And it happened again... Team AS turned into team S, well that’s because Alli joined our group because Sanaa was to good at this and she was not on our level. We later learned that when you take out a cord from a group of them, it’s really satisfying, but we also learned how to connect things. There were 3 main things to connecting: Ground, VCC and volt 5. We connected the Arduino board to a small chip. That’s when I realized there were now two main groups. The advanced group and the basic one. I was in the basic one. We were gonna use moist sense, a sensor that senses water and depending on how much there is will change the color of an led light. The bell rang for lunch.
I had the feeling that I haven’t seen them in a while again, it was probably because they were wearing jackets. A sign that life is trying to deceive me. When we went back to the lab, we went to the composting bins, we all remember those, their smell, their aura, it was like dung mixed with yogurt and some classic H2 with some of that O, also known as 2 Hydrogen atoms and and an Oxygen atom fused together to make H2 of the O. But surprise surprise! It wasn’t smelly, well not that smelly. We talked about how we were gonna use our creation for these. We talked about it for a bit and went back to the class. We opened the moist sensor, connected it and we were done, almost. Now it was time to put it all in a box. And it was over, yay! Now we just needed to see if it worked... ... ... And it didn’t work. Wow, let’s just take out some wires... ... ... Yes it works. I am so proud.
The people who were in the advanced group come in and their project was so good. Their was a sensor called a distance sensor which sends someone a Mail when something is close to it. Why is that useful? When the bin is full, someone will get an email saying the bin is full and someone will empty the bin. I was overwhelmed. It felt like I ran a marathon and got first place, only to figure out I was the only one to participate in the marathon. My brain claps slowly, packs its suit case and abandons me. Now everyone went home. Now if you see in the atrium there will be a CCD bin with a distance sensor.
