Online circuit simulator



123D Circuits is an online circuit simulator for any student or interested user. Users can design using 100’s of online components and can have the finished circuits shipped to them. Use of 123D Circuits is free, but circuits must be bought to be shipped.


123D Circuits is an online circuit simulator where students can use hundreds of virtual components to design circuits. 123D Circuits was created for users to be able to practice engineering skills online without having to purchase expensive materials.


Once students sign in to the 123D Circuits site, they can immediately begin designing the circuit. The site provides a variety of tools for the student to use, including both Breadboard circuits and schematic simulations. Students can design both simple and advanced circuits, and can create both they physical circuit and the software behind it. The program gives users many simulated components to choose from, including LEDs, transistors, motors, oscilloscopes, and dozens of others.

Once finished with a board, a student can purchase the circuit and have it shipped to her home. Boards can also be shared with other users to receive feedback and spark others’ ideas.

123D Circuits can be used by anyone, whether student or adult.


123D Circuits is available on any browser.


123D Circuits is free to use. The price of purchasing and shipping circuits varies with the complexity of the circuit and the components used.
