Different Between Fuse and Circuit Breaker
What is the difference between a fuse and a circuit breaker? In electrical circuits, we identify two types of circuit safety, namely Fuse and Circuit Breaker.
These two components are designed as highly current sensitive devices and are placed in the current path.
If the current through this component is below the maximum current limit of this component, then this component functions as a closed switch that can deliver current.
When the current exceeds the maximum limit of the fuse and circuit breaker, both of them will function as open switches, so that the current does not flow into the circuit.
There are three basic differences between Fuse and Circuit Breaker:
- Fuse if the current through it equals or exceeds the maximum current of fuse, then the fuse will break and must be replaced.
While the circuit breaker if the current through it is the same or exceeds the maximum current from the circuit breaker, the circuit breaker contacts will open so that it is like an open switch position.
However, circuit breakers can be manually reset to change positions such as closed switches or can be used repeatedly without having to be replaced.
- Fuse is generally used for small currents, while circuit breakers are used for high currents.
- Most of the physical size of the Fuse is smaller than the Circuit Breaker.
Examples of using Fuse are in audio systems such as amplifiers both on active speakers to car amplifiers, voltage stabilizers, car electrical systems, television, radio and many more.
However, as technology advances, now Fuse has a feature that can disconnect and connect the circuit automatically, known as the PolyFuse fuse.
PolyFuse is a type of fuse used in electronic circuits that can break off and reconnect the current automatically.
Apart from Polyfuse, the names that are often used are polymeric PTC (positive temperature coefficient), multiFuse, or polySwitch.
The way polyfuse works is if the polyfuse have a maximum current limit of 2A, and the current through it is equal to 2A or more, then the fuse is automatically cut off. And when the current from 2A decreases, then PolyFuse will automatically reconnect.
With this advantage, polyFuse has been widely used in electronic to automotive devices as a very important component for circuit security.
Good use with low to high currents to prevent overcurrent. An example of the most common use of polyFuse is on the Arduino board.
What is Arduino? You can read the explanation in the article "What is Arduino".
If you are someone who likes Arduino or is working on a project with it, when you connect or accidentally connect Power VCC to GND, the Arduino board will turn off automatically and when the connection is disconnected, Arduino will be active again.
If this polyfuse is not used, then when you connect the VCC and GND, the microcontroller and other components may be damaged and burnt.
Thus a brief explanation of Fuse and Circuit Breaker, hopefully the article "Difference between Fuse and Circuit Breaker" can add to your insight in the field of electronics and electricity.

3 Ways to Arduino Reset
3 ways to reset Arduino with schematic and program code - In some cases arduino project, we will need arduino restart or a reset mode of microcontroller to position the program at 0x00000000, which will impact the reading of the program from the beginning.
There are 3 methods to reset the Arduino and this can also be applied to other AVR variant microcontrollers (reset arduino uno, reset arduino nano and other), "Hard Reset ","Soft Reset", and "Combination"
Hard Reset means that Arduino will reset when a trigger button is pressed, like we press the reset button microcontroller directly on the physical microcontroller (hardware).
Soft Reset means resetting the microcontroller via Program Codes (arduino reset command)
Combination means We will use the program code to trigger the reset pin so that arduino will read the program from the beginning.
A. Arduino Hard Reset
In the Arduino hardware reset method, we will need a button that is directly connected to the default arduino reset button pin.
Attention! in this hard reset method we don't say arduino boards like arduino uno, nano, micro and so on but we say atmega328, raight?.
In addition to the hard reset method, we give an example using the Arduino board.
For example ATmega328. The reset pin is on the PC6 pin. This microcontroller will reset if pin PC6 is in the LOW position.
So, if the reset button is pressed, PC6 will be connected to ground and a reset will occur.
To keep PC6 going HIGH as long as the button is not pressed, we need to use a Pull-up resistor to hang up at the HIGH voltage.
Common values of resistor pull-up is 10K. for the schematic you can see in the following image.
|Arduino Reset Button|
B. Arduino Software Reset
In the second program this is a simpler way to reset your Arduino. we using resetFunc to declare reset to address 0.
This method does not need a schematic.
For program code arduino software reset, please upload the following arduino reset code program to your Arduino, then open Serial Monitor.
C. Arduino Auto Reset (Combination of Software and Hardware)
This method combine hardware and software. Pin reset arduino will triggered by other digital pin.
Let's say we using pin digital pin 2 in this tutorial. you can use other digital pins, according to your needs. Look at this image.
|Arduino Reset Software|
connect digital pin 2 to the reset pin. Upload the following program to your Arduino board, then click Serial Monitor. You can see whether your Arduino board has successfully reset or not.
How this method work?
We first define the reset pin used, which is digital pin 2. Then for the setup () function, at the beginning of the program we immediately apply digital pin 2 to output High logic (1).
This results in the microcontroller never being "reset", because the microcontroller will reset when given Low (0) logic.
We initialize serial to be able to display data to Serial Monito with the command Serial.begin (9600).
Then in this part of the setup () function we give the command to the Serial Monitor that the Reset was successful. Why? Because when the reset occurs, it will definitely read the setup () function first and will tell us via the serial monitor that the microcontroller has been reset.
In the loop () function, the main command that does the reset is digitalWrite (pinReset, LOW);
When the reset pin receives logic Low (0) from digital pin 2, the microcontroller will reset quickly, and will read back the setup program () then loop ();
However, when the reset does not occur, the serial monitor will provide information. Reset failed, because we have made the command Serial.println ("Reset Failed");
