Embedded Systems is a form of engineering that is used to integrate hardware, software, and sensors of all kinds into a single unit that can be used in all kinds of everyday machines, from cell phones to household appliances. The development of such systems requires constant proficiency and technical knowledge of the engineer that specializes in this field, called an 'Embedded Engineer'.

An Embedded Engineer is somebody who creates the firmware based on user requirements, makes sure the unit can properly and safely interact with any other device or incoming data; develops, calibrates and tests the system, and troubleshoots any problem when something goes wrong.

Here's some projects that our expert Embedded Engineer made real:

  • Developed customized control solutions for industry automation and robotics
  • Connected various sensors with different configurations and enabled communication between them
  • Preparation of vehicles for data and communications management task, such as onboard computers, devices or communication links
  • Integrate differents systems, such as GPS navigation devices or audio streaming systems in machines
  • Transfer data securely between two points, by means of communications links over wireless technologies or wired networks.

Embedded Systems technology is a complex yet powerful area for anyone trying to build something custom for their business or their personal use. A dedicated engineer can make sure that any idea a client has in mind becomes reality by providing the expertise needed. At Freelancer.com clients often hire talented embedded engineers that make all kinds of projects real. So if you have an idea that requires embedded engineering creativity, post your project today on Freelancer.com to start bringing it to life!

Wled() Esp32() Issues: Inputs (switch) need a preset (scene) for each state. It can't just turn a state on or off (e.g. in reverse > brake is triggered and brake gets overlayed on top of reverse > when brake is disabled it has to switch back to the default state instead of reverse). ⦁ The only version that has been stable enough even for testing has been the nightly build and still remains laggy. ideally it would be a minimal version with only the bare requirements that would leave room for change ⦁ state updates are laggy and sometimes flash or only partially change(memory and led library and little fs). ⦁ everything breaks...
