digitalLab is a simulator for playing around with digital logic gates. You can add components such as AND, OR, XOR, NOT, NAND, NOR, XNOR and a 7 segment counter.

You can wire them together to form simple binary circuits and add binary SWITCHes to power them up as you wish. You can simulate the circuit in auto-clock trigger mode or manual mode.

Note that each gate has a trigger leg located midway at the bottom. If it's wired, that gate will clock only with respect to triggers on that leg. This way you can try out Shift Registers etc.


Options are available to prob each wire to see the Boolean value it holds, making learning easier. The auto trigger time can be adjusted from 1 sec to 10 seconds or can be set to manual trigger.


You have various options to share your circuits with your friends. You can email the circuit as an attachment or copy the circuit in a text form. There are options to upload picture of the circuit in Facebook and twitter too.

Please note that the pictures of the components are NOT per any industry standard, they are only meant to make learning the logic behind binary arithmetic easy for students.

TRY LOADING THE SAMPLE CIRCUIT TO GET A PICTURE ON HOW TO USE THE SIMULATOR.

Kindly note that this is not a fun game... This is a study tool. You can enjoy it only if you understand binary...And the graphics is not great...please don't expect funny rainbow colors here...
