Line Following Robot

In the past, I have had many birthday gifts of moving toys and small robots, but I would always end up taking the toys apart I could never put them back together because I never understood how it was built or even what parts belong where, and so I went looking for answers. I didn’t find out which parts go where nor could I make them work again but nevertheless, I stumbled into the world of ‘Do it your self (DIY)’ electronics. Soon after, I decided to order an Arduino and started playing around with it. I started with turning on a simple led bulb, then moved on to making tunes with buzzers, displaying my name with a 7-segment display and changing directions with motors slowly upping the difficulty and broadening my knowledge,

Until I finally took upon the challenge of building a fully electronic machine with my knowledge and experience. I wanted it to be moving. After I made it move around a set path, I anticipated being satisfied but I felt I could do more, especially because moving around a prebuilt track was boring. Using light sensors that detect the amount of light reflected ( Using a combination of IR sensors ) I could finally achieve my vision, It was able to move around any track that I made on the ground. After a few new additions with changeable speeds and light sensitivity controls, the robot was complete. It worked even better than expected and I was very pleased with the result.

My understanding of how electronics work was amplified 10-fold, and as a plus I now understood how my childhood electronic robot toys worked and could make them work once again.
