![]() ![]() ![]() Arduino dimmer for led lights how to#This design however is for a single light fitting but does show how to make a fairly simple thyristor controlled light dimmer under computer control.Įxecutive Summary of the Microcontroller Controlled Light DimmerĪ light level controller includes a microcomputer controlled light switch which responds to a manual tap or a longer manual depression of the switch in order to initiate various control modes for a light source. Of course later control systems such as X10 implement a control system using the mains wiring and this can control multiple lights in various different ways (note that Insteon and Zwave are more reliable and faster than X10). The design also includes the idea of preset lighting levels so you can return a light to its previous level instantly. Their switching action is interpreted by the micro to mean different things.įor instance a momentary flick of the switch initiates a fade action whereas a longer press of the switch will cause a greater light level change. these switches do not just do on and off functions. It uses two switches connected to the inputs of a microcontroller to act as the user interface i.e. This project, a microcontroller controlled light dimmer fromġ985, enhances the operation of a light switch and fits into the same space as a normal light fitting.
