Now scroll down to see how to connect the subsystems to key components and view the Block Diagram.

Point to the components here to find their names

Now slowly drag the input module
across to touch the power module on the left.

Select your process module(s) by scrolling up and clicking on the next process button in the table. Repeat to add the other process and output modules chosen in your Block Diagram.

Now select the input you require

Use IP1 + crocodile clips to try other switches.

The IP2 and IP3 modules have a built in push to make switch and can be used to quickly connect input and process modules together. In order to connect different types of switches or to connect directly to an output subsystem, use IP1 instead and connect the switch via crocodile leads to the plug positions on IP1, shown on the left.

If you want to make an angle sensor replace the moisture detector with a 500K rotary potentiometer using the middle connection and one of the outer connections.

Model your system now with real components. Use the
panel on the left to select the input
subsystem you chose earlier.
