    Needed: We're looking for someone to join our small team who is proficient in coding in Python, MicroPython, C++ or a similar micro-controller language in order to integrate an ESP32 or similar board with other hardware. Our need is to enable communication between commercial off-the-shelf hardware, firmware and software and then use Blynk, or a similar platform, to develop the machine-human interface. This is a drone (UAV, unmanned aerial vehicle) related project so a good familiarity with basic mechanics and dynamics is necessary. ArduPilot familiarity would also be advantageous, but not necessary. Multiple environmental and situational sensors will need to be integrated, so logical programming will need to be written to include these sensors and flight actuators (servo or stepp...

    write a C program that interface together via a LabJack U3-HV. Purpose of this Design: Optical Sensor Alarm with Buzzer The purpose of your project is for a piezoelectric buzzer to sound on and an LED to turn on optical sensor circuit is interrupted. When the sensor is not interrupted, the green LED output will be off and the buzzer will be silent. When the sensor is blocked, the green LED output will turn on and the buzzer will sound on. The sensor state must be read and displayed to the user every 0.25 s, regardless of its value. Method 2: Exit program after 15 seconds of continuous running and monitoring. To test your project, run the code and trigger the alarm several times while the code is running to see the two outputs change states. The interface should conform to the specs lis...

    Need a resource to help with determining liquid versus solid inside a cavity. Inside that cavity a portion is solid and a portion is liquid and that changes as temperature changes. It would be ideal if an off the shelf sensing device could be used for a rapid prototype in order to be able to "profile" how the phase change occurs while temperature changes. Further it would then define an "alarm" based on a specific profile of the phase state which can cause an alert or a tie into another control system causing change in the overall process. It would be a requirement that you have specific experience with sensors (Ultrasonic or similar) with the ability to rapidly prototype. The Project Budget will be based on the experience of the team that is working on this and t...
