Im making a track for marbles as a school assignment. I got some experience with arduinos but not photo resistor so i dont know how to implement it in the code.
I want the photo resistor to act as a switch so when it dosent receive any light(blocked by a marble), the servo will be triggered.
[u]So this is what i want the code to do:[/u]
*See if the photo resistor is "triggered"
*Have a variable delay that runs in the loop (when the ldr is triggered)
- Move the servo 180 degrees after the delay
*delay after the 180 movement
*Move the servo back to its original position (0 degress) after the delay.
I would also like to have a led that show when the photoresistor is triggered!
[u]Here is the parts:[/u]
*turnigy 9g servo (180degress of motion
*Photoresistor 2-20 kohm (got it set up like this right now http://www.arduino.cc/en/uploads/Tutorial/switchCase_bb.png)
[u]I got access to these parts:[/u]
*Alot of diffrent values of resistor and potentiometers
*An arduino mega 2560
small capacitors with diffrent values
Im looking for help with the code, Preferably the hole code for it because of the lack of time. I know thats alot to ask for but i really need help with this! Im getting better at programing the arduino, but im not on this level :D
