John thanks for the second link, I've done a copy and paste
Here is an example of countdown using a for loop:
1234567891011
// countdown using a for loop
#include
using namespace std;
int main ()
{
for (int n=10; n>0; n--) {
cout << n << ", ";
}
cout << "FIRE!\n";
return 0;
}
10, 9, 8, 7, 6, 5, 4, 3, 2, 1, FIRE!
I don't think there is a better way to learn then to see an example of how its done.
Here is my working code: with better comments
#include <Servo.h>
Servo myservo1; // create servo object to control a servo
// a maximum of eight servo objects can be created
float pos = 0; // variable to store the rotary switch input
void setup() {
myservo1.attach(9); // attaches the servo on pin 9 to the servo object
myservo1.write(pos);
delay(3000);
}
// the loop routine runs over and over again forever:
void loop() {
int sensorValue = analogRead(A0); // read value from rotary switch
if (sensorValue > 100 && sensorValue < 200) // rotary switch position 1
{
// rise and fall code
for (pos = 12.5; pos < 18; pos += .1){ // goes from 12.5 to 15
// in steps of .1
myservo1.write(pos); // tell servo to go to position in variable 'pos'
delay(25); // waits 15ms for the servo to reach the position
}
delay(3000);
for (pos = 18; pos>=12.5; pos-=.1) { // goes from 15 to 12.5
myservo1.write(pos); // tell servo to go to position in variable 'pos'
delay(25); // waits 15ms for the servo to reach the position
}
}
else if (sensorValue > 200 && sensorValue < 400) // rotary switch position 2
{
pos=13;
}
else if (sensorValue > 400 && sensorValue < 600) {// rotary switch position 3
pos=14;
}
else if (sensorValue > 600 && sensorValue < 700) {// rotary switch position 4
pos=15;
}
else if (sensorValue > 700 && sensorValue < 900) {// rotary switch position 5
pos=16;
}
else if (sensorValue > 900) {// rotary switch position 6
pos=17;
}
myservo1.write(pos);
}
I really happy with how the program is coming along, due to all the help I have recieved. Next thing on my to do list is wire the switches to my breadboard and start experimenting.
John I was looking Jeremy Blum vid on youtube and seen a familiar name in the recommendations John NYCCNC is that you?
I've subscribed anyway, lots of very interesting vids to look at. I am a cnc'er myself, I've got a small vmc which I also use to turn small parts on which is what I made the air raid on, I've also biult my own router table.
