Deep Look Into Arduino

Nowadays Arduino is Very popular Among Students Because it is Very Easy to learn Arduino and it has multiple Plugin products that make the Arduino quite simple but a very effective Development board. Now Let's dig into the Arduino.

From the Left Side of the picture, We can See the Arduino Uno Development board. This Board Has 13 Digital Input and Output pins and 6 Analog Input Pins. From 13 Digital pins, 6 pins support PWM function. There are Multiple Arduino Gears that Enable the Arduino to do unbelievable Works. Arduino Gears are called Arduino Modules. There are some Awesome Modules like Touch Screen Module, Bluetooth Module, WiFi Module, etc,.Now Let's talk about Hardware and Circuitry about Arduino.
1.Power Adopter

1.Power Adopter: A black color round shaped female adapter is attached to the Arduino board which is useful when we need to separate Arduino from a laptop or Desktop.the power adapter can take power from 5V to 12V. It also has a power regulating circuit because the Arduino microcontroller only tolerates Voltage up to 5V.
2.USB-B Adopter

2.USB Adopter: A Rectangular Shaped Metalic USB type B USB Adopter is used to transfer data from Computers to Arduino. The USB transfer the Program Data to the Arduino using USB Signals (Voltage level Signal). These USB signals are cannot Program the Arduino, Because  Arduino and Other Microcontrollers are using TTL logic ( 1's and 0's). So the USB signal should be Converted to a TTL logic signal. So for that Arduino Using another Microcontroller which is programmed to Convert the Signal to TTL. There are other Chips also in Market, For Example, "FTDI Chips", "CH340" IC. These are quite familiar Chips in the Market. The Chip doesn't only convert the signal and also make the communication into Serial Communication. Because all microcontrollers using Serial Communication.
3.Microcontroller and Supporting Parts

3.Microcontroller and Supporting Parts:  In Arduino "Atmel ATMEGA328p" Microcontroller is used as a brain. Which has 28 pins, and there is a Crystal Oscillator which is the Heartbeat of the Arduino. Normally Arduino contains 16 MegaHertz Crystal Oscillators. There are Some Capacitors and resistors that are used to Power Control and Device reference point purposes. We can see There are two sets of pins each set consist of 6 pins they are the same pins but in a different location. They are called ICSP (In-Circuit Serial Programmer) pins. Which are used to Bootloader purpose or to connect other devices which need ICSP Connection. There is totally 4 SMD LEDs, One is for Power Indication, Two LEDs indicate Rx and Tx transmission. Then one LED connected to pin 13 to Check programs and other purposes.

4.Reset Button: In the top right corner, we can See a push-button placed that button is called the Reset button which reset the microcontroller by Grounding the Reset pin of the microcontroller. When the Reset button has pressed the program in the microcontroller is Started from the initial point.

Arduino Project : Dynamic Delay time using Potentiometer

Dynamic Delay time in Arduino Hello Friends!... Welcome to Arduino Projects Section. Today we are going to make a dynamic delay time in Arduino based on the potentiometer input. To make Dynamic Delay time in Arduino we need the following Components, 1.Arduino Development Board ( I am using Arduino Mega You can any Board from Arduino family) 2.Potentiometer 3.LED 4.Arduino IDE that's it. These are the components we need to make Dynamic Delay time in Arduino. if you are not familiar with what is Potentiometer, Here is a Quick Definition: Potentiometer: The potentiometer is a Variable Resister which varies when the knob of the potentiometer rotates the resistance of the potentiometer change based on changing the length between the Source and Drain point. Circuit Diagram The Following Diagram (Picture) Will show the Circuit diagram of Dynamic Delay time project, Dynamic Delay time Circuit This is the Circuit diagram of the project. The LED is connecte...
