Line following robot using formula flowcode buggy

[safdar.ayub]

Hello there
i am trying to do my final year project at university on rechargeable line follower robot using formula flowcode buggy and i am using low voltage detector sensor which i fixed on 5 volts so when the voltage of battery gets low to 5 volts from 6 volts. The system start to move to the recharging port; could anyone please help to guide on;

1) how do i connect the output from the low voltage detector sensor to the input port of PIC micro controller flowcode buggy?
2) how can i check which port of the PIC is free?

Regards

Safdar

Hello Safdar,

The circuit diagram for the FF can be found here.

Let me know if you need any further info.

Hello,

From the looks of it all the analogue inputs are currently being used by the Formula Flowcode. You could maybe disconnect one of the bits you don't need eg the MIC circuit.

Here is a list of the analogue enabled pins and their function.

RA0 - RA5 - IR distance sensors.
RB0, RB1 - Line Follow sensors.
RB2 - MIC
RB3 - LDR
RE0, RE1 - Motor Control
RE2 - USB detection

Thank you very much indeed Benj for quick response. Now i'll check it again and will try on MIC availability
