Schematics

Due to some missing components/modules in TinkerCAD, I had to replace them for a complete schematics. 1. Relay modules: there are no relay modules, I have replaced them with the components the relays are made of. You can use also this configuration, it will work the same. 2. LED strips - I have replaced them with only 1 LED, they will work the same with 1 or 100 LEDs. 3. Interruption sensor - it is actually working as a switch button so this is the best replacement I could do.
