Software Update

Problems Faced

  • Reed switches were not sensitive enough for magnetic tape.
  • Only 3 analog to digital converters on chip.

Actions on Problems

  • Changed code to suit LDRs.
  • Chose to not use the ADC's and plan to use the LDR's digitally. If they provide a voltage of over 2.25V then PICAXE will read as logic 1. If under 2.25V then logic 0 will be read.

Future Intentions and Learning Outcomes

  • LDR's will need to be calibrated for light conditions in the room.
  • Debug code on buggy testing in order to remove faults and include possible failsafe.
  • Include extra code for unique additional functions which will be revealed on competition day.

Current Situation

  • Code for both line following and signal reading modes is complete, tested and fully operational.
  • Input output variables may change but are easily edited in the code.
