Looking for a simple circuit to control the light intensity ... we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips”- for ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

To the human eye, it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all ...
