3 RGB leds
Our product should bring three RGB LEDs to indicate various things in one object. So we have to see how it worked an RGB LED to incorporate it into the product and the Arduino. Firsly we've seen that there's many ways of connecting LED'S depending on the type you have. All of them have 4 legs, but the function of the each leg changes. Some of them are R-GROUND-G-B, other are R-G-GROUND-B or R-5V-B-G. After taste all the options, our LED'S need to be connected the following way, which is R-5V-B-G:
At first, we thought it Led RGB worked like a normal LED, except that had several inputs for different colours. But when we did the first tests, we realized that RGB LED's operate in a different way. First, the output of the LED must go to the 5V instead of Ground, which is what a normal LED works. Then, we observed that in such as Digital as Analog, the activation of Led’s was reversing than normal. That is, for lighting the LED (Digital) has scheduled LOW instead of HIGH, and turn it off, you should also program in reverse; and lighting the LED (Analog) program has 0 instead of 255, and turn it off, you should also program in reverse. Finally, we note that entries for different LED colours are different between RGB LED's. Therefore, we had to discover what order colours have our input Led's.
We create simple code to learn how to use them. The following codes are, firstly a simple blinking led in three colors, secondly the same blinking but activated with a button, then three blinking LEDs activated with three buttons, and finally we've try to adabt the LEDs to the Loop PseudoCode, just like our project will do, but instread of buttons, pressure sensors.
