• Still Going.....

  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 :)

• Project Enclosure and PSU :)

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

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

• Progress, of sorts

  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

  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
  }

  Just tested the servos with sensors as a proof of concept. Will need to work on smoothing and fine tuning the angles,possibly with gearing/levers.

• Extra sketches

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

• parts ordered

  haydn jones • 03/29/2015 at 15:52 • 0 comments

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