Basic Stamp 2 Project 1 - Tri - color LED

This is my first Basic Stamp 2 Project. I control a Tri - Color LED by typing the letter of the color (G or B). I couldn't use the red color because i didn't have the proper resistor...




Oh and the Basic Stamp 2 Micro controller is made by PARALLAX Inc.

NOTE: The resistor depends on the led you're using. To calculate the necessary resistor go to this webpage:

http://metku.net/index.html?sect=view&n=1&path=mods/ledcalc/index_eng...

Code :

' {$STAMP BS2}
' {$PBASIC 2.5}

Dat VAR Word ' Make a Variable called Dat


LOW 2
LOW 3

DO ' Start a loop.

DEBUGIN Dat ' Write the letter typed on the terminal to the variable.

IF Dat = "g" THEN ' Wait for g being typed
LOW 2
HIGH 3 ' If so, put pin 3 on high, which will turn the led Green.
DEBUG "LED Is now green." ,CR 'Indicate that the led is green.
ELSEIF Dat = "b" THEN ' Wait for b being typed.
LOW 3
HIGH 2 ' If so, put pin 2 on high which will turn the LED Blue.
DEBUG "LED Is now blue." ,CR ' Indicate that the led is blue
ELSE
ENDIF

LOOP ' End the loop.

You know if u get some variable resistors, you can make any color.

@TheBasicStamp you can also use a digital pot to fade between the colors

@xXjose130Xx That is true. I thought of doing that but I only had one =(
