#Here's an awesome Robot project | |
### duration project: 2h | |
Materials list | |
1. Arduino uno | |
2. light sensor | |
3. cardboard | |
##how to | |
1. Step 1 | |
![alt text](http://www.slipperybrick.com/wp-content/uploads/2009/08/little_ken.jpg "Overview Robot") | |
2. Step 2 | |
<br> | |
<b>Markdown works *fine* in here.</b> | |
3. Step3 Arduino code | |
<br> | |
<!-- language: arduino# --> | |
void setup() | |
{ | |
Serial.begin(9600); //start the serial monitor with 9600 baud | |
pinMode(13, OUTPUT); //we mostly use13 because there is already a built in yellow LED in arduino which shows output when 13 pin is enabled | |
} | |
void loop() | |
{ | |
LDRValue = analogRead(LDR); //reads the ldr’s value through LDR which we have set to Analog input 0 “A0″ | |
Serial.println(LDRValue); //prints the LDR values to serial monitor | |
delay(50); //This is the speed by which LDR sends value to arduino | |
if (LDRValue < light_sensitivity) | |
{ | |
digitalWrite(13, HIGH); | |
} | |
else | |
{ | |
digitalWrite(13, LOW); | |
} | |
} |
