In an interactive light sculpture, for example, colors and patterns may change based on what people are doing nearby, creating a dynamic and engaging piece of art.

Components of a Development Board

Microcontroller or Microprocessor

Microcontrollers (MCU) or microprocessors (MPUs) are the heart of every development board. Code is executed and computations are performed by this "brain" of the board. Embedded software typically uses microcontrollers, while complex systems use microprocessors. The Raspberry Pi board uses a microprocessor whereas the Arduino board uses a microcontroller like the ATmega328P.

Power Supply

A stable power supply is necessary for development boards to function properly. External power adapters, USB cables, and batteries can all supply power. Voltage and current are supplied to the board by the power supply component. The input power of some boards is converted to levels suitable for the board and its peripherals by voltage regulators.

Input/Output (I/O) Pins

Interaction with the external world is dependent on I/O pins. Sensors, actuators, and other peripherals can be connected to a microcontroller or microprocessor by using these interfaces. Digital and analog inputs and outputs can be configured on these pins. It can interface with many components thanks to its 14 digital I/O pins and 6 analog input pins, for example.

Communication Interfaces

For data exchange with other devices, development boards come with a variety of communication interfaces. The following interfaces are common:

• USB: Used for programming and power supply.

• UART (Universal Asynchronous Receiver/Transmitter): For serial communication with other microcontrollers, computers, or peripherals.

• SPI (Serial Peripheral Interface): A high-speed synchronous communication interface for connecting sensors and memory devices.

• I2C (Inter-Integrated Circuit): A multi-master, multi-slave, packet-switched, single-ended, serial communication bus.

• GPIO (General-Purpose Input/Output): Pins that can be programmed to perform a wide variety of tasks.

Memory

Flash memory and RAM are two types of memory found on development boards. As the board operates, data is stored in the RAM, while firmware and application code are stored in flash memory. Arduino Uno, for instance, uses SRAM and flash memory of 2 KB and 32 KB, respectively.

Oscillators and Clocks

Clock circuits and oscillators provide timing signals for microcontrollers and microprocessors. It is these components that ensure synchronization and proper performance of the board's operations. A stable clock signal is generated by a crystal oscillator on most development boards.

Connectors and Headers

A development board can be expanded by attaching additional modules and shields via connectors and headers. Modules such as cameras and displays use connectors such as pin headers, USB ports, and power jacks.

LEDs and Buttons

There are usually LEDs and buttons on development boards to provide a basic user interface. A LED can indicate power status or be used for debugging, whereas a button can always be used as an input device. Arduino Unos, for instance, have built-in LEDs on pin 13 that are useful for debugging and indicating status.

Debugging Interface

A debugging interface is a tool for troubleshooting software and debugging bugs. There are several ways to debug a device, such as JTAG connectors, serial debugging interfaces, and onboard debugging tools. Coding and hardware issues can be identified and fixed with these interfaces.
