Question
Need help constructing a remote control car as well as the arduino code for the following:
Sound (voice) activation to start (also to stop, optional).
Create a tone sequence to emulate starting the car ignition before moving. You can use/modify one of the Arduino examples (file ®Examples ®Digital ®tone??? (modify one example))
Moving forward: while moving forward the car checks for obstacles
Moving backward: While moving backward the car performs the following functions:
turns the front wheels (using the front motor) left or right.
flashes led (red)
sounds a buzzer
Sensing the light level of the surrounding environment
Turns on the headlights when it is dark
Sensing the temperature of the environment
Turns on the fan when temperature exceeds a certain threshold level
Controlling the car speed (different speeds for forward and backward)
If you can help, thanks!!
Here's the sample code for the melody
"
#include "pitches.h"
// notes in the melody:
int melody[] = {
NOTE_C4, NOTE_G3,NOTE_G3, NOTE_A3, NOTE_G3,0, NOTE_B3, NOTE_C4};
// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
4, 8, 8, 4,4,4,4,4 };
void setup() {
// iterate over the notes of the melody:
for (int thisNote = 0; thisNote < 8; thisNote++) {
// to calculate the note duration, take one second
// divided by the note type.
//e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
int noteDuration = 1000/noteDurations[thisNote];
tone(8, melody[thisNote],noteDuration);
// to distinguish the notes, set a minimum time between them.
// the note's duration + 30% seems to work well:
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
// stop the tone playing:
noTone(8);
}
}
void loop() {
// no need to repeat the melody.
}"
