Today we built a very simple electroacoustic oscillation using the battery, speaker driver and paper clips. It’s good to know that hacking technology is not as incredibly complicated as I thought it was.
Next week we worked with breadboard and built more complicated electronic oscillator circuits using some capacitors, resistors, led lights, pressure sensors and orange (acting as capacitor I believe).
As I am a complete beginner in electronics, I prepared this very simple guide to what’s what
Capacitors exist to store an electric charge or energy. They can then release the charge or energy when it’s needed. In the electroacoustic circuit, they indicate the frequency of the sound (higher capacity (larger capacitor) – lower frequency – lower sound). Capacitance is the measure of how much electrical energy is stored in an object, such as a capacitor used in an electronic circuit. The unit for measuring capacitance is the farad (F), defined as 1 coulomb (C) of electric charge per volt (V) of potential difference.
Resistors literally resist the flow of electricity, either to limit the current for a given applied voltage (electrical pressure) or to allow a certain voltage (pressure) to build up when a given current flows. They consist of insulating materials (like ceramic) that lower the ability of electrons to flow on the surface and therefore slows down the current. Resistance is measured in Ohms.
