Voice Activated Electric Easel for Quadriplegic- Trouble with Arduino code within Res = 1 to control Linear Actuator
Hello, using Movi connected to Mega and a ServoCity Dual Motor Controller for voice activated control of linear actuator, also using stepper motors. Cannot get working (works without Movi triggering) actuator code to work within a Movi Res. Voice portion is recognized by Movi- believe problem is that code within the Res. I suspect that timing might be a problem but I'm quite the ignorant on many fronts. Code snippet below- I pasted the Loop code into Res 1 for the Sample beginner LightSwitch sketch. Any help WAY appreciated!
///////////////
int LeftDistance = 0;
void setup() {
pinMode(10, OUTPUT);// connects to servo signal input to ServoCity dual motor (linear actuator) controller.
}
void loop() {
if (LeftDistance < 20) { //value of 20 gets about 1/4 inch of actuator movement
digitalWrite(10, HIGH);
delayMicroseconds(1000); // 1000 piston goes out; 2000 piston goes in;
digitalWrite(10, LOW);
LeftDistance = LeftDistance + 1;
}
}

digitalWrite(10, LOW);
LeftDistance = LeftDistance + 1;
}

Without seeing the entire code, if you copied the above code right within after the res==1, the motor will exactly do one step after sentence 1 is recognized. The good news is that there is an easy fix: replace the "if (LeftDistance < 20)" with a "while if (LeftDistance < 20)". So your code should look like this:
void loop() {
signed int res=recognizer.poll(); // Get result from MOVI, 0 denotes nothing happened
if (res==1) { // Sentence 1.
while (LeftDistance < 20) { //value of 20 gets about 1/4 inch of actuator movement
digitalWrite(10, HIGH);
delayMicroseconds(1000); // 1000 piston goes out; 2000 piston goes in;
digitalWrite(10, LOW);
LeftDistance = LeftDistance + 1;
}
}
// ...
}

Thanks for the response Gerald- still can't get it to work. Will continue to beat my head against the wall in effort to solve, and after donating more blood- will get back to you. This is for my paralyzed brother in law who paints with a mouthstick. He'll be using voice commands to make easel- painting go up/down, left/right, in/out. Have built the structure and got it work, manually triggered. Once I've got this going I'll share project details on your forum- it's pretty sweet (and a noble cause to boot!).

Gerald- got it going (5 out of 6 movements, 1 to go). thanks for your input sir!

Congrats! I am looking forward to seeing a video!
