Color Detector
Buggy Base also contains two Color Detector sensors on the underside, right next to the ColorLEDs. The Color Detectors are capable of detecting color. These are useful when following along a color line. The Color Detectors are referenced as Color Detector "A" or "B" depending on the side it is on.
Block: Detect Color
The Color Detector can be utilized using the Color Detector - Detect Color block.
|
Function: This block control the Buggy Base to follow (trace) along the chosen color line.
|
Example 1: If a Color is detected, then play a note on the Buzzer
| Note: this example is performed in online mode. If you have overwritten the firmware when using "offline mode", please follow the instructions to reset back to "online mode". |
|
|
Description: When activated, The program will loop forever checking for when Color Detector "A" detects green, then the Buzzer will play note C4 for 1 second.
Block: Read Color
Retrieving the raw value from the Color Detector can be accessed using the Color Detector - Read Color block.
|
Function: This block reads and returns the raw value from the color detector while having the corresponding ColorLED set to a specific color.
|
Example 2: Read and display the raw value from a Color Detector
| Note: this example is performed in online mode. If you have overwritten the firmware when using "offline mode", please follow the instructions to reset back to "online mode". |
|
|
Description: When activated, Corey will say the raw value currently detected on Color Detector "A" with the corresponding ColorLED set to red. Test different color surfaces to see the raw values change.
