7-segment LED displays were revolutionary, finally providing a clear, readable and low-power numerical display solution. We’ve got plenty of other cheap display options now, but sometimes you just ...

Eight-pin microcontrollers offer numerous peripheral features. However, the maximum number of I/O pins available is often limited to six, since two pins would be required for the chip's power supply.

The I2C-7SEG board is a 5-pin CMOS device that provides 4-digit of 7-segment display using I2C bus. There are no external components required.The I2C-7SEG board is a 5-pin CMOS device that provides ...

[Peter Lehnér] has designed a brilliant 7-segment flip-segment display that doesn’t really flip. In fact, it doesn’t use electromagnets at all. This one is 3D printed and hand cranked. It’s a clever ...
