Electronics

Here we connected a phone, which was playing music, to an oscilloscope. It displayed its accompanying wave on the screen.



Here we lit up a LED light (pictured in red next to the black wire) on a breadboard connected to a power supply. The higher the voltage, the brighter the LED shined.






















We built a sound amplifier using the breadboard, the same power supply, as well as capacitors and resistors. We also used a transistor, which amplifies electronic signals. It is composed of a collector, base, and emitter. We also learned about a diode, which only allows current to flow through one direction through it.
