This will then generate a schematic library from all the components on the schematic and from here you will be able to rename them, change them etc. Place the opto and then select Design-Make schematic library as seen below. Create schematic libraryįirst of all, place the component which is most similar to the one you are planning to use, in this case that component is Optoisolator1 This component looks almost exactly like above except there are no arrows on the phototransistor. So the symbol were are going to create looks like this. The TCRT is an very similar to an opto-isolator and for this component I could just use one of the pre-existing symbols, but I thought for future reference I would create one now.

(Sometimes this isn’t necessary as you are probably just making a footprint for an existing symbol, such as a resistor etc. However even though we have now finished the footprint, we still need a valid circuit symbol to link the footprint to. This one is for the TCRT5000 line sensor. The finished footprint could look like anything, but I thought I would just paste an example of what one might look like. It helps to already be in the process of placing a pad before you press insert though. Hover over the pad with the mouse and then press INSERT this will zero the dx and dy values so then anything else you place from that point will be referenced to the centre of the pad. How to set the origin to the location of the mouse Once in this menu you can simply drop pads down and create an outline to make the Footprint.

This will add a PCB library to the project, which you can access at the bottom (circled in red). It might be that you just want to add a new component to an existing design in which caseįirst right click on the project and then click “Add new to project” and then PCB Library. Well first of all you need to click “File>New>Project>PCBProject”Īnd then I am guessing you are going to want to add a schematic so click “File>New>Schematic” and this should be added to the PCB project.
