A crystal oscillator is an electronic circuit or device which is used to generate a stable frequency with the help of a crystal instead of a tuned circuit. The crystal when vibrates, it acts like a resonator & as a result generates an oscillated frequency. The resonator circuit uses a crystal to generate the oscillation.

The 1N5819 is a Schottky Diode with forward voltage drop of 600mV and a forward current of 1A. Since it has a very low forward voltage drop it can be used in reverse polarity protection circuits, unlike a normal diode which has more than 1V as forward voltage drop 1N5819 only has 600mV drop across it when 1A current is flowing through it.

Compared to normal diodes Schottky diode also has relatively faster switching speeds and hence can be used in high frequency switching circuits. The reverse blocking voltage for 1N5819 is about 28V only which is kind of a downside for all Schottky diodes so make sure this does not affect the performance in your circuit.

It is an RM065 500 Ohm Trimpot Trimmer Potentiometer.  The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver.

AMS1117-1.8V, 1A, Voltage Regulator IC is a series of low dropout three -terminal regulators with a dropout of 1.8V at 1A load current. AMS 1117 features a very low standby current 2mA.

AMS 1117 offers thermal shut down and current limit functions, to assure the stability of chip and power system. And it uses a trimming technique to guarantee output voltage accuracy within 2%. Other output voltage accuracy can be customized on demand, such as 1%

It is an RM065 5K Ohm Trimpot Trimmer Potentiometer.  The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver.

A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode.

This is called a power diode because of its high forward current and reverse voltage with a power dissipation of 6.25W. For 1N5408 Diode, the maximum current carrying capacity is 3A it withstand peaks up to 200A. Hence we can use this in circuits that are designed for less than 3A.  The reverse current is 10uA which is negligible. These diodes have a slow recovery time so in modern electronics it is being replaced by other advanced diodes.
