Circuit Building Aim: To continue constructing the circuit within our house Keywords: Parallel circuit, light emitting diode, series circuit This lesson we continued with the task of creating our electrical circuit that is to power the lights and other electrical components within our houses. The criteria in terms of components that have to be included in the house are: at least 2 lights (regular bulbs or LEDs) and at least 1 ‘other’ component. This other component can be literally anything that you would like as long as it runs on electricity. For our house we are including 4 LEDs and 1 ceiling mounted fan. As mentioned in previous blogs, the transformer doesn’t have the required voltage for LEDs, meaning we have to use a battery pack as our power source. This is an urgent issue to fix, as we are not using the lights that are being supplied, but 4 LEDs. Last lesson I mentioned the switches that we were using made of split pins and a paper clip, however an issue arose from the use of the switches and that is in order for the switches to allow the flow of electrons they must be held down. This becomes both annoying and impractical when operating the lights and fan, so instead we created a new switch which flows the same design, but the clip slides onto the pin, rather than having to be held down. This means that the electrical components can be activated without having to constantly hold them down, making them the much more practical switch. The fan that we have implemented into our house is ceiling mounted to allow better access to the wires and also improved aesthetics. Due to our house having no ceiling, the ‘ceiling’ mounted fan is actually mounted onto a piece of cardboard that is affixed to the wall via masking tape. This also means that the fan can be removed easily, to allow for adjustments to both its position and wiring. Lesson Summary:
Attached our ceiling fan Created new switches and then attached 5 to the house Completed the input/negative side of our circuit.
