Arduino TCRT5000 Distance Sensor

TCRT5000As a project for the Ottawa Arduino Challenge – TCRT5000 i decided to use my sensor to measure the distance between the end of an arm and some object.  The basic concept was to design a machine which would maintain a consistent distance from an obejct.  I only spent a few evenings on the project but I think I was successful in completing what I set out to accomplish.  I had a few other ideas so maybe I will try them too, but for now, this will be my submission.

Design Process

 

Using my favourite 3D CAD software I threw together a simple machine based on the TCRT5000 sensor riding on the bottom of the arm and a Micro 9G Servo which I had lying in the parts bin waiting for a project.   After a few hours in design mode I was ready for the fabrication.  One of the awesome things about owning a 3D printer and a Laser Cutter is that you can go from imagination to reality is such a short period of time.  After picking out some scrap pieces of hardboard from the junk pile I flicked the power switch and a few minutes later I was ready for glue it together and installing the components.  In total this part of the process maybe took half an hour of fiddling around.  I am still fascinated by this every time I make something!…

 

Sample Code

 

Next was coding.  Below is a very simple sketch I came up with to accomplish my mission.

    Congratulations, a day there in the future (maybe next life, incarnation) be able to do what you do.
