Arduino is an open source platform made to interact with hardware by using the software. Arduino Uno Price in Pakistan is pretty costly but here at circuit, you can find it at cheap price. Arduino boards are able to take inputs like light on a sensor, a Twitter message or a finger on a button. It can turn it into an output like starting a motor or turning on an LED. You can instruct your board what to do by giving a set of instructions to the microcontroller on the board. For this purpose, you use the Arduino programming language, and the Arduino Software (IDE).
Arduino UNO is the best board to get started with microelectronics and coding. If this is the first time you are tinkering with the platform, the UNO is the best board you can start using. Best solution for Arduino Uno price in Pakistan is provided by Circuit.PK. The UNO is the most used and well documented board of the entire Arduino family.
Arduino was born at the Ivrea Interaction Design Institute as a basic tool for rapid prototyping, targeted at students without knowledge in electronics and programming. As soon as it reached a wider community, the Arduino board begin changing to adapt to new challenges, differentiating its offer from plain 8-bit boards to fully functional products for IoT applications, 3D printing, wearable and embedded environments. All Arduino boards are entirely open-source, empowering users to create them independently and eventually adapt them to their specific needs. The software, too, is open-source, and it is growing through the users’ contributions around the globe.
Arduino Uno is a board built on the ATmega328P. It has 14 digital input/output pins (out of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a power jack, a USB connection, an ICSP header and a reset button. It contains all the basics needed to support the microcontroller, you just have to simply connect it to a computer with a USB cable or provide some power to it with a AC-to-DC adapter or battery to get started. You can tinker with your UNO without worrying too much about any hazards, in worst case scenario, you can change the chip for some dollars and start over again.
The ATmega328 on the Arduino Uno is preprogrammed with a bootloader that make you able to upload new code to it without the using an external hardware programmer. It communicates with the original STK500 protocol (reference, C header files). You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or something similar.
