Analog Input Homework Assignment

For this project I had difficulties with just about everything. I am unable to complete the homework due to the LDR not working and I am not sure why. From this project I have learned that when connected to the 5V on the arduino it goes on the positive side of the breadboard and the GND goes on the negative. I also learned that the A0 chord, LDR, and resistor all have to be on the same row. When I first started this I had difficulties putting everything together because I didn't understand where anything went. Because I cannot get this part of the homework to work I do not believe I am able to continue and will have to ask for help tomorrow.

for the sensor value I cannot put the code in to test it out but I think in the void loop section I would add:

analogValue = analogRead(0);

// print it out in many formats: Serial.println(analogValue); // print as an ASCII-encoded decimal Serial.println(analogValue, DEC); // print as an ASCII-encoded decimal Serial.println(analogValue, HEX); // print as an ASCII-encoded hexadecimal Serial.println(analogValue, OCT); // print as an ASCII-encoded octal Serial.println(analogValue, BIN); // print as an ASCII-encoded binary

// delay 10 milliseconds before the next reading: delay(10);

For creating the light I would use:

if (brightness <= 499) { brightness = 0 ; }

For the second part:

if (brightness >= 700) { brightness = 300 } else if (brightness <= 300 || brightness >= 700) { fadeAmount = -fadeAmount; }
