Integrated Circuits (ICs) are at the core of our hi-tech world. They are inside everything electronics. In the coming robot/IoT/AR/VR era, the application and deployment of ICs will become even more prolific and widespread. IEEE Volta is an app developed by IEEE Solid-State Circuits Society (SSCS) aiming at educating the general public about the importance and the history of ICs over the years. The application is named after Alessandro Volta, a pioneer of electricity and power. The puzzle themes feature the most significant ICs that have changed our way of living. Through learning about these ICs, users gain the historic perspective about this fascinating field and shed some light on what the future ICs may bring for us.
