Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

For those of us who remember LED calculators, the HP 5082-7400 series red “bubble” displays hold a special charm. Available in 3, 4, or 5-digit varieties, these multiplexed 7-segment displays ...

The finished circuit can display numbers ranging from 0 through 1023, in connection with a 10K preset pot attached to the analog input A0 of the Arduino board. This 4 -digit 7-segment display section ...

“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano. The segments are controlled by 18 MAX7219 ICs which can control up to 64 individual LEDs or 8 ...

Or (what I’m doing for a remoteable display) is 8 7-segment displays on a single I2C chip: the AS1115, with a single resistor for brightness control. $4.50 single-chip solution for up to eight 7 ...

I love to read through project suggestions and examples for the Arduino and other platforms. It keeps my mind constantly running with ideas for projects. I was recently provided a copy of ...
