WebStep 8: Building the Test Circuit. Now we need to test the sensor and see if it was really worth making it. We need an Arduino board and an LED to test our flex sensor out. We also need a 22kΩ resistor. It will be better if we use a breadboard because that will make the circuit-building process easy and fast.

WebBegin by sketching a rectangular resistor on a blank sheet of paper using one of the graphite sticks. The rectangle should be at least 1cm in width, and should be as thick as you can get it with the graphite stick (try to have consistent thickness throughout). Try to make a true rectangle, as you will need to measure its exact area later. WebThe resistivity of a material is defined as the resistance of a piece of material having a length of one metre and a cross sectional area of one square metre. Graphite is a pure carbon …
http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/rstiv.html WebCrystalline graphite is not simply a bunch of graphene layers piled one on top of the other, but is highly ordered structure. Graphite is composed of layers of carbon atoms that are arranged in 6-membered, hexagonal rings. These rings are attached to one another on their edges. Layers of fused rings can be modeled as an infinite series of fused ...
WebA resistor is an electical component that controls the “flow” of current in a circuit. Think of it like a faucet that controls the flow of water so that just the right amount comes out.
