Webtrain Decoupling Adam Kadolph EE451 Bradley University Advisors: Dr. Irwin, Dr. Schertz Week 11 Monday 2/26

2 Outline Last Week Current Week My Test Programs –Sensorx –Sensor4x –Autodecouple –Decouple What’s Next?

3 Last Week Code a basic program to send DCC signals to the train depending on the measured voltages from the sensor –Tuesday Lab (Morning) Code another program to measure values from four photocells –Tuesday Lab (Afternoon) Combine the two programs –Thursday Lab (All day)

4 Current Week Get my last test program to work –Problem with DCC signal Tweaking with my sensors –All 4 sensors need to be as close together as possible

5 Timeline

6 My Test Programs Sensorx (working) –Program to test one photocell –Display on LCD –Used with test track Sensor4x (working) –Program to test four photocells –Display voltages on LCD

7 My Test Programs Autodecouple (not working) –Exclusively for Automatic Decoupling –Voltage from photocell circuit will change train speed Decouple (working) –Manual Decoupling Testing –Automatic Decoupling Testing

8 What’s Next? Mounting the sensors on the layout –Test program will tell where to Coding –Lots of assembly coding –And more coding
