- 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.
