Day 18 - Diodes and Transistors





We were able to create an amplifier on the breadboard shown below, according to the diagram shown above:

This breadboard set up created an amplifier that increased a 3,000Hz wave at 0.3 V with a transistor of 2N3904



This resulted in a 100 times amplification from the original.  The two waves on the screen are the wave being emitted by the function generator, as well as the amplification from the breadboard. The original voltage was 0.3 and the new one was 20-30 V.


We created the amplifier below based on the diagram shown above, using an LM386 audio amplifier

This set up finally did produce sound that we streamed from an alternative rock soundtrack from Bianca's phone, but it was mainly static.
