Day 3 : Bipolar Junction Transistors (BJTs)

The first rule of hot dog cooking club is to not get cheap hot dogs that smell like hair when they are cooked.

In order to get a thoroughly cooked dog, Make sure you us a large voltage source.

This is what circuits in the future will look like. Actually it is LEDs plugged in across the hot dog in different orientations relative to the dog. Only the ones that are lined up parallel to the dog and in the correct direction light up.

This is a voltage source and a capacitor. A graph of the voltage from the capacitor when it is supplied with a square wave.

It is important to be comfortable when you analyze circuits. This is a voltage do-hickus which changes the voltage across the second resistor by adjusting the ratio  of the resistors it has a proportional effect on the voltage across the resistor.

This is a circuit conversion to create a more simple circuit that can be easily analyzed for the adjustments in one resistor.

There is a photo-resistor in this circuit which decreases the resistance in the system so that the LED receives a higher current when it gets dark.

This is the circuit using the photo-resistor.

This is the circuit of how the photo-resistor changes the drain current on the supply allowing more current to flow through the transistor and into the LED, Using a Light Dependent Resistor and a Bipolar Junction Transistor.
