LED sensor

LED SENSORS Required hardware : 1. Audrino 2. 10k ohm resistor 3. LED 4. 220 ohm Resistor 5. Breadboard Circuit . connect 3 wires to audrino . red wire goes from 5V to breadboard, black wire goes from ground to breadboard, the white wire goes form analog input to breadboard. . plug the LED longer part (the anode, positive part) to pin 13 through 220 ohm reisitor and the smaller part(the cathode, negative part ) to the ground(GND) in audrino. Code You can adjust the speed of LED blinking.
