The Shift Register IC has the following pins:-1)GND - This pin is connected to the Ground pin of the microcontroller or the power supply. The easiest development environment is the Arduino IDE. These pins accept inputs in the form of Analog signals and return values that range between 0 and 1023 (that’s because the Arduino Mega has a 10-bit Analog to Digital converter or 210 resolution). There are three common lines to all the peripheral devices: UART stands for Universal Asynchronous Receiver and Transmitter. It allows us to connect the board to the computer. Thus, PWM can only mimic and simulate the effects of a pure analog signal, it can never perform pure digital to analog conversion (which generally requires some active components like capacitors and inductors). 555 Timer IC is one of the commonly used IC among students and hobbyists. Arduino Mega Pin Diagram Arduino Mega Pin Configuration Controller Pins: RESET: (Reset input) A low level on this pin for longer than the 4 clock cycle will generate a reset.

The I2C uses two lines to send and receive data: a serial clock pin uses (SCL) and a serial data (SDA) (SDA) pin. It means, that an analog value is being modulated on a digital signal. These pins can be used to trigger an interrupt on a low value, a rising or falling edge, or a change in value. We can use these pins to program the Arduino board’s firmware. The Arduino digital pins can read only two states: when there is a voltage signal and when there is no signal. I/O Reference Voltage (IOREF) – This pin is the input/output reference. The program is uploaded to the board serially from the computer through the USB cable. These pins are used to power the LCD's backlight. It is the two-wire serial communication protocol. It enables the Arduino to communicate with serial devices. Fig. It’s recommended to press this button every time we flash the code to the board. This kind of input is usually called digital (or binary) and these states are referred to as HIGH and LOW or 1 and 0. Arduino IDE (Integrated Development Environment) is required to program the Arduino Uno board. Sending a signal to this pin does nothing. Anything below 4.88 mV is considered 0 and above 4.99 V as 1023. Barrel Jack – The Barrel jack or DC Power Jack is used to power the Arduino board using an external power supply.
