Introduction and Aims We will
be using the I/P 3 subsystem to produce a negative going voltage. This
follows on from the previous task when we used I/P 2's push switch to
produce a positive voltage. We will now be sinking the next module and
using an L.E.D. (see OP1) as the output of our system. |

Modelling the above System/Circuit There are different ways to model and test circuits before components are soldered to a P.C.B. Modelling is an important stage as it helps you spot any problems and make modifications easily. Method 1: Breadboard Using
this method, components are pushed into the interconnected holes as
shown in the diagram below. The lines shown indicate which holes are
internally connected. Method 2: Computer Simulation To begin, you will need to ask your supervisor which simulation software is available on your PC. This method allows you to build up your circuits quickly and cheaply in a virtual environment. Remember though, it will not give you hands-on experience of the components you will be using when finally soldering your PCB. Method 3: Using OnTrack modelling hardware
