I want to control the switching on/ off of multiple 1-3 watt LED lights at different times without manual intervention. We are narrating a story through pre-recorded voice and each scene has a set of figures that need to be highlighted. The idea is to switch on the light of the figure relevant to that scene, switch it off and then move to the next. This is for about 10-12 lights and spread across a total of 2.30 minutes. Any ideas?
