74HC595
When a project needs more outputs, the 74HC595 shift register can expand output control while using only a few microcontroller pins. This example is based on the 74HC595. The datasheet refers to the 74HC595 as an "8-bit serial-in, serial or parallel-out shift register with output latches; 3-state." In other words, you can use it to control 8 outputs at a time while only taking up a few pins on your microcontroller. You can link multiple registers together to extend your output even more.
4N35
The 4N35 optocoupler transfers a signal using an internal LED and phototransistor, providing electrical isolation between the input and output sides of a circuit
PN2222 NPN Transistor
Use the PN2222 NPN transistor as a switch to control loads that require more current than a microcontroller I/O pin should supply directly
Electrolytic Capacitor
An electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal. The benefit of large capacitance in electrolytic capacitors comes with several drawbacks as well. Among these drawbacks are large leakage currents, value tolerances, equivalent series resistance and a limited lifetime.
Ceramic Capacitor
A ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.
1N4007 Diode
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. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1 A it withstand peaks up to 30 A. Hence we can use this in circuits that are designed for less than 1 A. The reverse current is 5 µA which is negligible. The power dissipation of this diode is 3 W. Applications of Diode: ● Can be used to prevent reverse polarity problem ● Half Wave and Full Wave rectifiers ● Used as a protection device ● Current flow regulators
