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); } }
Competitive Advantage:
1.Convenient & Friendly Customer Service
2. Low Prices Direct From Factory Suppliers
3. Fast Delivery Around The Globe.
4. High Quality With Global Standards.
5. 3 year factory warranty
