Light Sensor
Sparki has three light sensors that detect the level of light that hits them:
How It Works
These sensors are phototranistors that are connected to Sparki so that the more light that hits them, the higher the voltage they send to Sparki.Using the Part
With the basic Sparki code in place, you can measure the light sensor using this command:|
1 2 3 |
sparki.lightLeft(); sparki.lightCenter(); sparki.lightRight(); |
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |
/******************************************* Basic Light Sensor test Sparki has 3 light sensors in the front, one each on the left, middle and right. This program shows how to read the sensors and display the information on the LCD. ********************************************/ #include <Sparki.h> // include the robot library void setup() { } void loop() { sparki.clearLCD(); // wipe the screen int left = sparki.lightLeft(); // measure the left light sensor int center = sparki.lightCenter(); // measure the center light sensor int right = sparki.lightRight(); // measure the right light sensor // write the measurements to the screen sparki.print("Left "); sparki.println(left); sparki.print("Center "); sparki.println(center); sparki.print("Right "); sparki.println(right); sparki.updateLCD(); // display all of the information written to the screen delay(100); } |
