Day15 


//Simple Motor Speed Control Program
const int MOTOR=9;    //Motor on Digital Pin 9
void setup()
{

    pinMode (MOTOR, OUTPUT);
}
void loop() { 
    for (int i=0; i<256; i++)
    {

        analogWrite(MOTOR, i);
delay(10); } 
    delay(2000);
    for (int i=255; i>=0; i--)
    {

        analogWrite(MOTOR, i);
delay(10); } 
    delay(2000);
}





i got the code to make the motor run , but the potentiometer didn't
change the speed of the motor, but as a on and off switch. 
i strongly think its because i didn't wire it correctly.

the SD logging code modified to get temperature and read the data. The output was working in class , but the arduino doesn't want to run for some reason now. the code does work  if there is the speed.txt . the setup of the sd card reader and the i2c . wiring for general is sometimes confusing for me so this part took time from the wring.

the code for the sound lab using the cheap speaker. as with all the labs and project using the speaker, trying to get the thin wires to get into the breadboard and having it stay there took the longest. the lecture code for the recursive and non-recursive code for factorials the output for the factorials. they both seem alright and bad. JDoodle did have a small cap so i think higher numbers just gets capped.

the code using the I2C  temperature sensor and using the RGB LED to display the temperature. the code was easy , but the wiring was confusing. Trying to wire it correctly part of the problem to get it to work. this is before the lights were connected, and i was used on the lab. The pin that wasn't used threw me off on the wiring. The elevation code, but modified for the homework. This HW was fairly easy because it was just mainly creating loops and counters or copying and modifying the already existing loop. This code is actually from the final as i can't find the original code. the output of the elevation code.
