HW 9: PIR and light sensor (based on material from lab 5) Connect your PIR sensor and your CdS cell (light sensor). The PIR and CdS sensors will control the LED behavior as follows: When the PIR is triggered the LED is on. When the CdS is uncovered and the PIR sensor is untriggered, the LED is off. When the CdS cell is covered and the PIR sensor is off, the LED blinks. The initial blink rate should be one complete cycle in 1 second (use delays of 500 ms for on and off). Every time the PIR is triggered, the delay time should be cut in half (blinks faster). You can use the reset button on the Arduino to reset the program back to 1 second cycle.

Transcribed Image Text:HW 9: PIR and light sensor (based on material from lab 5)
Connect your PIR sensor and your CdS cell (light sensor). The PIR and CdS sensors will control the LED
behavior as follows:
When the PIR is triggered the LED is on.
When the CdS is uncovered and the PIR sensor is untriggered, the LED is off.
When the CdS cell is covered and the PIR sensor is off, the LED blinks.
The initial blink rate should be one complete cycle in 1 second (use delays of 500 ms for on and
off). Every time the PIR is triggered, the delay time should be cut in half (blinks faster). You can
use the reset button on the Arduino to reset the program back to 1 second cycle.
Transcribed Image Text:You should be able to reuse the code from the
2nd lab as well as shown below:
const int LED=9;//The LED is
connected to pin 9
OD UNO
Ardu
const int PIR=2;//The PIR is
connected to pin 2
void setup()
{
pinMode (LED, OUTPUT);
pinMode (PIR, INPUT);
digitalWrite (LED,HIGH);
delay (500);
digitalWrite (LED,LOW);
