Turning ON/OFF light bulb using Arduino and Relay

~ Abilash, Pratap.

Abilash and Saranya made a relay circuit during the Electronic session with Vimal, so the goal was to turn ON and OFF the AC bulb with the delay of 1 second which was connected to the Arduino and Relay. The Arduino was connected to the laptop and bulb to the 230v Alternating Current through the relay.  Pratap captured the video as a sudden surprise and made the learning rigorous.




The Morning session of Day 4 started with insights that the participants learned in the previous day, which was followed by a video “Story of Stuff”.The Story of Stuff is a short animated documentary about the life cycle of material goods. The documentary is critical of excessive consumerism and promotes sustainability.

Later a session was taken by Naveen where he taught the methods to draw graph and Coordinate Geometry using GeoGebra and some tasks were given to the participants. The participants were excited when different projects of the 9th graders were displayed by Arun.

After returning from Lunch , a short video on Semour Papert was shown.The Video was about how Papert recognized that computers could be used not just to deliver information and instruction, but also to empower children to experiment, explore, and express themselves.

The next session on GeoGebra was handled by Murali which included concepts like drawing shapes, midpoint and interactive inputs. The day was closed with a Quotation.


Puzzle Solution Box

~Saranya, Murali, Abilash

Each week a Mathematical puzzle is placed on the STEM Land notice board, where the interested students who wants to solve the puzzle writes the answer and drops the answer in the Solution Box. The Solution box which they have been using was made of cardboard,that was pretty weak and did not have a Lock on it.The Students were worrying that the answers which they drop into the box may get spread among the others and wanted a Permanent solution where their answers were safe.


So we(Saranya,Muruli,Abilash) planned of making a Stronger Solution Box. So we cut out the plywoods into the measured size and started nailing it. Seeing the half Solution box being ready, the students showed their interest by asking us if any help can be done by them.As still the Box was not completely ready and the hinges and latch needs to be fixed.We gave the remaining work that needs to be done to them.Though they were struggling a bit at the beginning ,soon they competed their work.And guess what….The Solution box was ready.
