The Vision Project

After drilling and cutting my teensy-lc arrived from HAD, and the servo arms were literally a headache. I found a nice design for a glue stick linear actuator, and I am incorporating the teensy as the (or an alternative) controller. I need to find out if I can use a common send pulse for multiple range finders to reduce pin count.Will update as i learn more :)

Just got these and I now have a Mega, so full steam a head.

I think it's dremel time.....

I have pushed my Uno as far at it can go, and am now waiting for a mega from china, so I can connect my whole array. Looking for a good supply of tension springs as an alternative to extra gears. I wont post any images today, but my design is (will be) based on a hat. I will need a cheap 3d print service for my levers and frame at some point if anyone has any recommendations.

#include <Servo.h> 
Servo myservo;  // create servo object to control a servo 
int ang;    // angleofservo

const int TriggerPin = 8; //Trig pin
const int EchoPin = 9; //Echo pin
long Duration = 0;

void setup(){
myservo.attach(2);  // attaches the servo on pin 2 to the servo object 
pinMode(TriggerPin,OUTPUT); // Trigger is an output pin
pinMode(EchoPin,INPUT); // Echo is an input pin
Serial.begin(9600); // Serial Output
}

void loop(){
digitalWrite(TriggerPin, LOW);
delayMicroseconds(2);
digitalWrite(TriggerPin, HIGH); // Trigger pin to HIGH
delayMicroseconds(10); // 10us high
digitalWrite(TriggerPin, LOW); // Trigger pin to HIGH

Duration = pulseIn(EchoPin,HIGH); // Waits for the echo pin to get high
// returns the Duration in microseconds
long Distance_cm = Distance(Duration); // Use function to calculate the distance

Serial.print("Distance = "); // Output to serial
Serial.print(Distance_cm);
Serial.println(" cm");
ang = map(Distance_cm, 0, 1023, 0, 179);
myservo.write(ang);

delay(100); // 10 readings per second
}

long Distance(long time)
{
// Calculates the Distance in cm
// ((time)*(Speed of sound))/ toward and backward of object)

long DistanceCalc; // Calculation variable
DistanceCalc = ((time /29) / 2); // Actual calculation in cm
//DistanceCalc = time / 74 / 2; // Actual calculation in inches
return DistanceCalc; // return calculated value
}

A few sketches while I'm waiting for parts. Any thoughts on the array layout?

Have ordered sensors and servos, will try to add some sketches that make sense to people other than me.
