DCACLab is a great way to introduce basic electronics concepts to students! I have looked for a long time and have not seen other websites or software showing real-time simulations that could hold the attention of middle school students until I used DCACLab. The visuals are engaging and the efficiency of being able to show relationships between voltages, currents, and resistances in series and parallel connections is remarkable. I didn't know, Samir, the founder of DCACLab, prior to using the simulator, but when I contacted him about certain features in the Lab, he was and has been very supportive. Needless to say, tech support is beyond exceptional and is done in the spirit of enhancing teaching and learning electronics! My students and I are very, very grateful!

The visual you have included for electron flow is fantastic and really helped them understand how current is divided in a parallel circuit.

Student at Holland College

It is enjoyable to interact with it. The user interface gives me the sensation of operating a real Relay unit in a laboratory.
