Title:
Light to Voltage Converter |
||||||||||
Potential/Voltage
Dividers
and Sensors |
|||||||||||
In this starter project, we will be modelling a potential divider circuit.
With the help of a multimeter, we will show how the output voltage can
be made to change as we vary the amount of light falling on its input
light sensor (Light Dependent Resistor - LDR).

Modelling the 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 more 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, ask your supervisor if circuit simulation software is available on your PC. This method allows you to build up your circuits quickly and cheaply in a virtual environment but will not give you hands-on experience of the components you will be using when finally soldering your P.C.B.. Method 3: Using OnTrack modelling hardware
