Software / connecting a lazer range finder to a linear actuator,
« Last post by dexringer on August 05, 2016, 02:36:48 AM »
I would likt to connect a lazer range finder to a linear actuator, and be able to prest the position/distance. IE if the wall is 60 feet away, you can set it to return to that position when 60 feet distance is achieved again. This would hold true for all distance/position measurements programmed in.
Can this be done? I am sure it is possible, I just dont know where to start. Any help would be greatly apreciated, and thank you for acceptance into your forum.
Software / (arduino) move a servo with potmeter and buttons
« Last post by john33 on August 04, 2016, 10:33:26 AM »

for a project i have something which is getting me stuck.... so far.
I want to move a servo using a potentiometer, but also i would like to move the servo from the set  position by the potmeter with 2 buttons, button A turn left, button B turn right.

In my search for this problem i came to the solution to add up the value pos to val.
But so far this is not working.
This is the test sketch so far:

#include <Servo.h>

Servo myservo;
int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin

#define leftPin 2
#define rightPin 3
int pos = 90;
int delayPeriod = 50; // increasing this slows down the servo movement

void setup()
myservo.attach(9); // attaches the servo on pin 9 to the servo object
myservo.write(pos); // center the servo
pinMode(leftPin, LOW);
pinMode(rightPin, LOW);

void loop()
val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023)
val = map(val, 0, 1023, 0, 180); // scale it to use it with the servo (value between 0 and 180)
myservo.write(val); // sets the servo position according to the scaled value

if ((digitalRead(leftPin) == HIGH)&& (val+pos < 180))
else if ((digitalRead(rightPin) == HIGH) && (val+pos > 0))

What am i doing wrong ?

Misc / Hand Gripper Servo MOD
« Last post by MeccaNoid Madness on August 01, 2016, 04:49:28 PM »
This is my version of a hand gripper:

I am currently using the attached 2DW Robot Chassis. 2 geared DC motors are used. I am controlling the motors with an Arduino Leonardo and a motor driver that is essentially identical to Adafruit's Motor Driver v2.0. The issue is that when I supply power to the Arduino via either the USB cable (attached to my laptop) or via the power jack (with a 12V DC supply), the motors do what my code tells them to do. However, when I supply power to the motor shield via the power terminals using either 5, 6, or 8 AA batteries, the motors seem to just do whatever they want. They start by jerking around a little, then run continuously until I disconnect a battery. I have the VIN jumper attached to the shield, and the Arduino power LED says that it is on; it just doesn't seem to be transferring the proper instructions, but it does when I power the Arduino and not the shield. In all cases, the power LED on the shield is on.

Could anyone supply any insight?

I did this in LIM mode, this was longer then 2 min., so I had to string 2 LIMs in the video. I changed the voice to +30% pitch to sound more like MeccaNoid.

This was fun for me, I love Star Wars.

I have used it at school to show my students facial recognition and various other moves it can make.  I have also used lego mindstorms in my classes.

mainly I let it run around at home :)
