1 Channel Tracing Sensors For Arduino Module With Demo Code

Description: 

Tracing sensors, robots make the necessary  Using infrared light detection, anti-interference ability  

Sensor uses CTRT5000, high sensitivity, stable performance  

Operating voltage 5V, 

output low black line, a white line output high  

Exquisite workmanship, with indicator  With fixed bolt hole for easy installation 

Now we use the tracking module and a digital interface, 

 making  A tracing cue lights when tracing sensor senses a key signal, 

LED lights, otherwise off.

 test  code:

int Led = 13 ;/ / define LED Interface int buttonpin = 3; / / define tracing sensor interface int val ;/ / define numeric variables val void setup () { pinMode (Led, OUTPUT) ;/ / define LED as output interface pinMode (buttonpin, INPUT) ;/ / define tracing sensor output interface } void loop () { val = digitalRead (buttonpin) ;/ / digital interface will be assigned a value of 3 to read val if (val == HIGH) / / When the sensor detects a tracking signal, LED flashes { digitalWrite (Led, HIGH); } else { digitalWrite (Led, LOW); } }
