if you prefer) clips connect to so you can get the most out of it

we have found it works better when the step signal is steady (eg provided by a microcontroller's PWM timer output rather than software delays) and the speed is moderate

Cutting the trace that goes between the pads of each jumper allows the chip's internal 100 kΩ pull-down to pull that pin low

Adafruit 1.2" 4-Digit 7-Segment Display w/I2C Backpack - Yellow Category_DYNAMIXEL Servos general-purposeWhat's better than a single LED? Lots of LEDs! A fun way to make a numeric display is to use a 4 digit 7 segment display . LED 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, wouldn't it
