Your decoder should have 5 inputs (4 for the binary number and 1 for the decimal point). With respect to the statement in your original message: Design and implement a BCD to Seven Segment Display Decoder. Sevseg.begin(hardwareConfig, numDigits, digitPins, segmentPins, resistorsOnSegments) Also, each segment in the display must have a current limiting resistor. The display is formed by 3 digits with common cathode, with the cathodes driven by NPN transistors. I already modified the necessary lines of the code, but when temperature is below 100 degrees, then it shows me the leading zero, and I need to eliminate that zero. Please find attached the schematic and the code. ![]() Hello, I am working at a project and I need the following function to work with common cathode displays.
