In this video lesson we introduce the concept of Arduino Arrays, and illustrate by writing a simple program which inputs and prints a list of grades. The code from the video above is presented below for your convenience.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | float grades[25]; int numGrades; int i; String myPrompt; void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: Serial.println("How Many Grades? "); while (Serial.available() == 0) { } numGrades = Serial.parseInt(); for (i = 0; i < numGrades; i = i + 1) { myPrompt = "Please Input Grade: "+String(i+1); Serial.println(myPrompt); while (Serial.available()==0){ } grades[i]=Serial.parseFloat(); } Serial.println(); Serial.println("Your Grades Are: "); for (i=0;i<numGrades;i=i+1){ Serial.println(grades[i]); } for (i=0;i<numGrades;i=i+1){ } } |
