Adafruit 0.56" 4-Digit 7-Segment Display with I2C Backpack - Red STEMMA QT / qwiic Category_Arduino/LilyPad Arduino Available either as a bare

Available either as a bare pHAT or as a kit with 6 red or green LED modules (you'll need to solder them yourself)

it can preform very well even in dim environments

This is a full Python three implementation created specifically for small embedded microcontrollers

you can order the carrier board without any sensor and solder one in yourself

Works really well with any 3D printed project

A fun way to make a small display is to use an 8x8 matrix or a 4 digit 7 segment display . Matrices like these are 'multiplexed' so to control all the seven segment LEDs you need 14 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you but there's a lot of wiring to set up and they take up a ton of space. Here at Adafruit we feel your pain! After all,
