    <title language="eng">Microcontroller Programming of a Contactless Optical Position Measurement Device</title>
    <abstract language="eng">This thesis focuses on programming a microcontroller to receive and process data from a waveguide optic distance sensor, and to visualize the measured distance on a display screen. During the measurement process, LED moves above the 3D-printed D-shaped waveguide. The light transmitted through the waveguide is converted into photocurrents&#13;
by photodiodes located at both ends of the optical waveguide, which are then converted into voltage signals through specific electronic components. By computing the ratio of the optical power detected at each end, the relative position of the LED along the waveguide can be determined. In this project, a microcontroller is used to acquire the voltage&#13;
data, correct measurement errors, calculate the LED position, and display the result on screen in real time. Compared to manual calculation of photocurrent values, using a microcontroller for automated data processing greatly improves speed and efficiency. At the same time, real-time visualization enhances the system’s practicality and usability,&#13;
making it more suitable for future applications.</abstract>
