Edits for Diagrams

1. The diagram on [this page](https://www.futurelearn.com/courses/physical-computing-raspberry-pi-python/1/steps/161874) needs changing. Your house circuit uses AC, so the diagram is factually inaccurate. I thin the internals of a torch would be better. Perhaps show 2 batteries and a switch connected to the lamp.

1. The diagram and animations on https://www.futurelearn.com/courses/physical-computing-raspberry-pi-python/1/steps/161840#fl-comments show a single battery. This should really be 2 batteries in series (the +ve of the first connected to the -ve of the second). This will provide 3V which is enough to light an LED.

1. Can they also be edited so that the wires connect to the little bump on the +ve end of the battery

1. Circuit Diagrams and animations on https://www.futurelearn.com/courses/physical-computing-raspberry-pi-python/1/steps/140375. I want to stop using the ravine as a break in circuits, as this is not the correct way of doing things. Can the animations and diagrams reflect this way of connecting an LED and resistor.

1. Diagram of LED to change as in the edits above for [this page](https://www.futurelearn.com/courses/physical-computing-raspberry-pi-python/1/steps/138664)
