Project Description: I am seeking someone with experience in electronic circuit design and familiarity with EasyEDA to create a schematic that controls a 3-digit, 7-segment display. Each segment of the display has a forward voltage of around 15V. While it might be possible to use a MAX7219, it alone is not sufficient to handle the required voltage. Additional components or alternative solutions would be needed to achieve the objective. Requirements: The design must be done in EasyEDA. The circuit should be capable of controlling a 3-digit, 7-segment display with a forward voltage of 15V for each segment. A Bill of Materials (BOM) must be provided along with the schematic. The freelancer is expected to provide support in case of any questions or issues with the design. Deli...
