Cheap PIC controlled Helmet Camera using Sony LANC (Good for Extreme Sports)

Step 2 The circuit diagram

The circuit is very basic.


- The PIC is powered directly from the LANC cable.

- The Minicam is powered from a 12 volt battery pack via a switch

- There are 2 push buttons for Record and Stop

- 3 LEDs are used to show you the status of the camera


PIC connections:

RA0 - LANC from the camera
RB7 - Record LED
RB4 - Record button
RB5 - Stop button


(Please note, Step 4 is an update to this circuit, the power LED is connected to RA5 and there is a different source code)
