What our customers are saying


At a Glance: Arduino

First introduced in 2005 as a programmable microcontroller for students at the Interaction Design Institute Ivrea in Italy, Arduino is an open-source suite of microcontroller-based kits for creating digital devices, smart objects, and robots. A typical Arduino board is made up of an Atmel 8-, 16-, or 32-bit AVR microcontroller, a 16 MHz crystal oscillator, a 5-volt linear regulator, and a standard USB port for interfacing with your computer.

An Arduino developer can use C++, C, or Java with the Arduino integrated development environment (IDE) to create the sketches that program the sensors, actuators, and motors that control your digital devices. Expert Arduino developers on Upwork can debug your sketches, solve complex problems, and help you lay out the electrical components on your boards. Whether you’re looking to build your own custom temperature sensor, create a robot, or need to reprogram the hot water setting on your espresso machine, a seasoned Arduino developer can help bring your projects to life.
