Ήδη επισκευάσαμε ένα πολύμετρο και έναν φορτιστή.
Βρήκαμε και ιστοσελίδα όπου γίνεται προσομοίωση κυκλωμάτων, η οποία μάς στέλνει και μέιλ, όπως το παρακάτω:
When making a schematic, you often just need to draw your own components to represent input/output connections or custom ICs. See how easy it is to create your own custom schematic symbols in CircuitLab.
In the toolbox, scroll down to Annotation Tools, and then click and drag the Custom Part to your schematic:

Double-click on the part to begin editing it:

From here, you can resize the rectangle by clicking and dragging at the bottom right of the rectangle:

Click "P1" and change it to be "VCC":

Click the green + to add a pin and name it "D_POS":

Repeat, clicking the green + to add pins for D_NEG and GND:

Check the Show Pin Numbers checkbox and enter the pin numbers you'd like:

Double-click on an empty space on the schematic to see our finished symbol:

We now have a custom symbol which represents, for example, a USB port. We can wire this up as we'd like, and can use Ctrl+C and Ctrl+V to copy and paste it into another schematic, by running another copy of CircuitLab in another browser tab.
For more information about custom symbol creation, look at our documentation, or check out this 1-minute video:
