Arduino is an open-source computer hardware and software company, project and user community that designs and manufactures microcontroller-based kits for building digital devices and interactive objects that can sense and control objects in the physical world.
Uno
Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
“Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0. The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.

CSEduino v4
The CSEduino is the answer to a very low cost DIY Arduino like board. The CSE stands for Cheap, Small and Easy to build. With a very small budget of up to € 3.5 (5 USD) in parts it is possible to build this board with the required components. To be small some optimizations were made to the stripboard to accomplish its reduced size. The board is 4.5cm x 5.5cm. The circuit is adaptable to different requirements and it was made modular enough to be able remove the parts not needed and reduce its size even further. To be simple and easy to build I’ve used only THT - Through-hole technology. Avoiding SMD - Surface Mount Devices - components - as they are harder to solder and prone to errors. I’ve used the most common microcontroller used in Arduino Boards with THT - the ATMega328P (in PDIP format).
