Simple Electronic Circuit Example

The process carried out in the manufacture of an electronic circuit is carried out systematically with schematic creation up to the testing stage. Certainly in the manufacture of electronic circuits must be done by a team of experts in order to avoid fatal errors that can cause malfunctions in electronic devices made.  

To make it easier for us to understand the circuit and how electronic systems work can analyze the finished PCB scheme as a reference or learning in understanding how electronic components work in pcb schemes. Here's an example of some pcb electronics that you can learn about. 

1. Create the DC lighting circuit

This lighting circuit is an electronic scheme used to create a lighting system using DC current. Dc supply is used for small LEDs that have two terminals namely anode and cathode. Anode is +ve and cathode –ve. Here, the lamp is used as a load, which has two terminals such as positive and negative.
Terminal +ve lamp is connected to the battery anode terminal and the battery terminal is connected to the battery terminal. The switch is connected between wires/cables to provide DC supply voltage to LED light bulbs. Here's the series you've created

2. Create the Temperature Monitor Circuit


The range of temperature monitors is often used in various types of electronic devices. Temperature monitors are created as a tool to detect temperature levels emitted by electronic devices. In general, temperature monitors can provide a message if the device temperature is above the normal limit. In this series the indication is an LED light.

This circuit gives an indication using the LED indicator when the battery voltage drops below 9 volts. This circuit is ideal for monitoring small 12V battery charge levels. The battery is used in burglar alarm systems and portable devices. How this series works depends on the biasing of the base terminal of the T1 transistor.

When the battery voltage is more than 9 volts, the voltage on the base-emitter terminal will be the same. This makes the transistor and LED turn off. When the battery voltage is reduced below 9V due to utilization, the base voltage of the T1 transistor drops while the emitter voltage remains the same because the C1 capacitor is fully charged. At this stage, the base terminal of the T1 transistor becomes +ve and turns on. C1 capacitors released via LED.
