| Play the "Jingle Bells" or the "Mission Impossible" tune using one digital output of the Arduino, connected to a little speaker.
| There are dozens of LED flasher designs on the web. But this design is based on a special complementary transistor combination (which is n...
| I wanted to end my diarrhea of LED fader designs with a humoristic design. Though it looks like a bad joke, it still has a nice LED fade e...
| YALALF Yet Another Linear Analogue LED Fader Inspired by the idea of Arnoldus and plots of Clemens Valens.
| What do you get when you combine a capacitive sensor, wireless power transfer and a slow RGB colour changer ? Right, a magic lamp !
| Using a Twin-T sine oscillator to generate a non-linear, but still pretty good LED fading effect.
| Use the FET square law to linearize the brightness of a LED, so a linear brightness curve is achieved.
| LEDs and closed loop brightness control ? Or using 'ancient' techniques such as current squaring current mirrors ? Let's go analogue for a c...
