Wiremod is a user-created mod that significantly expands the sandbox capabilities of the game by adding a large number of pseudo-electronic components such as microcontrollers, logic gates, buttons, radios, gyroscopes, screens, GPS modules, sensors, laser rangefinders, speed sensors and much more. Wiring these components together allows the player to create a very large variety of electronically-controlled machines. It also features Expression2 (E2) general-purpose controllers, which allow the player to program the chip with a high-level programming language to compute inputs and outputs to control a wide swathe of elements. CPU modules, which use a Low-level programming language, allow similar capabilities, as well as the capability to render graphics on a digital screen, to be able to fully simulate a virtual computer. The use of Wiremod allows the creation of very complex contraptions, and everything from virtual computers to missiles, aircraft, spaceships and space probes, robots and drones; all constructed from components available in-game without the use of modded entities.
