Simple motor code

Projects Programming
1

I’m new to arduino and building a soft ramp up for a slot cars. I tried making a code from this site Robots + Big Data: Arduino Motor Docs
I can get the motor to start ramp from 0-30% in a second, and then ramp to 100% in second.
If I set start motor right away at 30% I can’t get a ramp after that. Coding is so confusing to me.

But this is what I really need

Want motor to start at 30% right upon power
Delay a second
Ramp up to 75% in a second
Delay a second
Ramp up to 100% in a second

Please post your code

#include <RBD_Timer.h>
#include <RBD_Motor.h>
 
RBD::Motor motor(6); // PWM pin
 
void setup() {
  motor.rampPercent(30, 300); // Launch control
                                // Use motor.setSpeedPercent(10) "hits power instantly 10%"
                                // Use motor.rampPercent(30, 300) "ramps up to 0-30% in .3 seconds"
}
 
void loop() {
  motor.update();
   
    if(motor.onTargetSpeed()) {
    // code only runs once per event
    Serial.println("Target Speed");
   
    delay(050);                     // Time between launch control and power adder
   
    motor.rampPercent(100, 500);    // Power after launch to finish
                                      // use motor.setSpeedPercent(100) "hits power instantly"
                                      // use motor.rampPercent(100, 300) "ramps up to 100% in .3 seconds"
  }
}

  delay(050);

If you want a 40 millisecond delay, why not simply delay(40);

TheMemberFormerlyKnownAsAWOL:

  delay(050);

If you want a 40 millisecond delay, why not simply   delay(40);

i have that changed, i was using 1000, 100 etc to see it in person while testing. this is going into a slot drag car that runs 22 ft in .7-1second
