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 ...

You can learn more about these less-known features by referring related articles/ tutorials/datasheets published elsewhere in this website/internet. As a bonus, you can build your own LED display ...

Her tutorial covers a simple LED circuit with a battery and a sliding switch, though she describes in detail how this can be expanded for more complex circuitry and offers good suggestions for ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.

The time circuits are now active, so now you can easily add a temporal display to your car well before a hover conversion. [Phil] used these LED displays, conveniently controlled by a four-wire ...

However Frank felt there might be cases where the brightness was too much for the work at hand, so he decided to build a dimmer circuit. In selecting a method of dimming the LED fixtures, Frank first ...

If a fault occurs with any of the series LEDs or its wiring, an open load condition can be created. In this situation, the voltage across the current sense resistor drops to zero. The control circuit ...
