DAY 10

This was a tough assignment creating the color sensor code and the color sensor circuit. Bardia had the pleasure of working on the infrared sensors ( it was really awesome that he made 2 IR sensors; that was very helpful for the competition). With the right resistors, around 10K on the LDR and 220 or the RGB LEDs, the circuit board flashes accordingly with different colored cards.

Making the board was another tough solderinng job.

Here the RGB sensor is processed by a Pic-14M. I will describe the programming in details once the proto-board soldering is done. Here's how the initial testing works. If the color sensor detect a large red reflection of the red card, then the indicator red LED flashes. When sensor picks up large green reflected surface, like th green card below, the green indicator LED flashes. Lastly, a blue reflecting surface will reflect a largely blue wavelength, that in turn will turn on both red and green indicator LEDs.
