Day 9

For today we had to create a program that lit up certain LEDs based on the distance measured by the PIR sensor Here's the code #include <Servo.h> const int SERVO =9; const int IR =0; const int LED1 = 3; const int LED2 = 5; const int LED3 =6; const int LED4= 11; Servo myServo; int dist1 =0; int dist2=0; int dist3=0; int dist4=0; void setup() {   myServo.attach(SERVO);   pinMode(LED1, OUTPUT);   pinMode(LED2, OUTPUT);   pinMode(LED3, OUTPUT);   pinMode(LED4, OUTPUT);   } int readDistance(int pos) {     myServo.write(pos);     delay(600);     int dist= analogRead(IR);     dist= map(dist,50,500,0,255);     dist =constrain(dist,0,255);     return dist; } void loop() {  dist1 = readDistance(15);   analogWrite(LED1,dist1);   delay(300);   dist2=readDistance(65);   analogWrite(LED2,dist2);   delay(300);   dist3=readDi...

Day 4

For homework i had to create an RGB LED that changes color depending on what button is pressed here is my code const int BLED=9; //Blue LED on Pin 9 const int GLED=10; //Green LED on Pin 10 const int RLED=11; //Red LED on Pin 11 const int BUTTON=2; //The Button is connected to pin 2 const int XBUTTON=3; const int YBUTTON=5; boolean lastButton = LOW; //Last Button State boolean currentButton = LOW; //Current Button State boolean XlastButton=LOW; boolean XcurrentButton=LOW; boolean YlastButton=LOW; boolean YcurrentButton=LOW; int ledMode = 0; //Cycle between LED states int XledMode=0; int YledMode=0; void setup() {  pinMode (BLED, OUTPUT); //Set Blue LED as Output  pinMode (GLED, OUTPUT); //Set Green LED as Output  pinMode (RLED, OUTPUT); //Set Red LED as Output  pinMode (BUTTON, INPUT); //Set button as input (not required)  pinMode (XBUTTON, INPUT);  pinMode (YBUTTON, INPUT); } boolean debounce(boolean last) {  boole...

For homework we had to generate a table based on user input here's the code //This program prints the altitude and velocity for a ballon over a given amount of time given in hours. #include <stdio.h> #include<math.h> #define FILENAME "balloon1.txt" int main(void){ double t; //t is in hours double alt_max,sum,start_time,end_time,alt,v, period; double time_incr,new_incr; alt_max=0; FILE *balloon; balloon=fopen(FILENAME,"w"); printf("Enter the start time,and end time, in hours:\n Values must be BELOW 48 hours \n"); scanf("%lf %lf",&start_time,&end_time); if(start_time > end_time) { printf("Please choose an end time larger than the start time."); exit(); } if(start_time<0 || end_time>48) { printf("Please enter values that are between 0 and 48"); exit(); } printf("Enter the time increment in minutes: \n must be BELOW 48 hours \n"); scanf("%lf",...
