Problem:
| | On page 144, the circuit diagram shows the 9-12 volt line going to pin 8 of the CA3140 operational amplifier. It should go to pin 7.
Also 0 volts is shown as going only to pin 19 of the PIC. It should also go to pin 8.

Solution:
| | The component layouts on page 145 are correct but please make the above changes if you are using your own layouts.
| |
|
Other Projects:
| | This change does not affect the other projects.
