Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

It is a combination of 8 LEDs (the decimal point -DP- is the 8th), which can be arranged so that different combinations can be used to make numerical digits. Just follow the schematic circuit diagram ...

Now, however, [Jose] has come up with an LED candle that solves all of these problems. (Original link to the project in Spanish.) The heart of the project is an Arduino Pro Mini, which is ...
