Making the robot was quite an easy task. It was surprising for me as I never really got along with science back in school. My fear of science was one factor that kept me away from exploring the electronics, so I finally decided to overcome it by taking this course. This course did help me refreshing the basics and also understanding it this atleast time.

SP road visit

This wasn't my first trip to SP road but since we had a long list, keeping up with it and understanding what each component is was a different experience. This trip helped us for future projects, as now we know the reliable place, general costing and where to get what from.

Introduction to Components


making your own battery

Making our own switch was the best activity, we were running around with multimeter checking the resistance of nearly everything around us. We used the leaves, the bark, light, heat and even us as switches. we connected 9 9v batteries together to match up the resistance of our bodies.

In order to make the LED glow, I ended up wasting a lot of LEDs as little did i know about resistors. I had just seen resistors vaguely back in school diagrams, but never used it.

Playing with Meccano was fun altogether, but adding a movement to it was fascinating. Initially I had some problems regarding the movement of the wings as the rod was too heavy for the axil but after using glue gun it started working. so the toy runs and the wings move too.

At first, Arduino seemed like a scary thing, but as we worked on it in the class together it seemed quite fun and explorative.

The magic wand was a collaborative project between me and Julia. Tilt sensor and LDR have been used in this wand. We added three colours of LED, only one glows at a time, all three have been coded to light at different angles.
