I agree wholeheartedly! I like to use the TM1640 and RGB LEDs. It's cheap, works well, requires a minimum of external components, and can convey a fair amount of information. It can also drive a 16x8 LED matrix if I do want something screen-like. Usually I'll control it with a Wi-Fi MCU like the ESP8266 or Pi Pico W. Total component cost, including board, sits around 5$ each with a minimum quantity of 5. |
