To invent the synthesizer you have to put all the pieces you received together:
This cardboard base will serve to gather all the materials.
Breadboard – Breadboards are the basis for assembling electrical circuits. They are accomplices to some of the greatest inventions of all mankind, with engineers, scientists and inventors using them to create the first prototypes of their grandiose ideas. The holes in the breadboard are linked together by a metal wire. For this reason, it is very important to respect the lines of the circuit diagram. If the legs of the LEDs are not in the same line as those of the resistors, for example, the circuit will not work.
SPEAKER – Speakers are electronic components that transform electrical energy into sound. They are very similar to buzzers, with the difference that they can generate several sound tones.
LED– turns electrical energy into light energy. He is a true superhero, transforming the way we light up our world by consuming less energy, being cheaper than all other lamps and light technologies!
Capacitor – The capacitor stores electrical energy. We “charge” a capacitor by connecting it to a power source. When we “turn it off” (or open the circuit), it will slowly discharge. These devices allow energy to be stored and transferred more flexibly.
The capacitor is normally cylindrical. It has polarity like the LED: a larger leg (the positive one) and a smaller one (the negative one).
Ceramic capacitor – stores electrical energy. We “charge” a capacitor by connecting it to a power source. When we “turn it off” (or open the circuit), it will slowly discharge. These devices allow energy to be stored and transferred more flexibly.
The ceramic capacitor is similar to a flattened disc. It has no polarity like the previous one.
Integrated circuit – Integrated circuits are better known as chips or microchips. They are essentially mini electronic circuits that help us to simplify other more complex circuits. They are a precious help!
Switch – Used to close or interrupt the circuit, thus turning any device on or off. In this experiment, it is used to turn the Synthesizer on and off.
Battery– The battery is the most generous component of all and without it our circuit does not work. Energy is stored in this chemical form, which is converted into electrical energy when inserted into a circuit.
Battery holder – where you will place the battery that will power the Synthesizer electrical circuit.
Resistances – Sometimes batteries are too generous, which is not always a good thing. If the LED receives too much energy, for example, it can burn out. To control the energy that reaches the LED and prevent disaster, we use resistors. There are stronger ones, others weaker. The colored stripes help us to distinguish them.
Jumper Cables – Electrical cables are used to conduct electricity from one point to another. They consist of copper, a conductive metal, covered by a plastic, often colored. The plastic allows us to pick up the wires without getting a shock!
Self-adhesive aluminum tape – This tape is made of aluminum, a conductive metal. It has the purpose of increasing the contact surface between our fingers and the stripped strands of the conductive wire.
Double-sided adhesive tape –The adhesive tape is a tape … with glue. You can have glue only on one side, the most usual, or both, the so-called double-sided tape
