Using this 4 - digit white 7 - segment display is easy. First, connect it to your circuit through the sixteen through - hole pins. Make sure the forward voltage doesn't exceed 1.9VDC and the current stays below 20mA to avoid damaging the LEDs. You can control each digit's decimal point, as well as the apostrophe and colon points individually. When handling the display, be gentle as it's a delicate device. For maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or humidity. If you need more information, refer to the datasheet.
