| This circuit detects if the temperature of an object became too high. The thyristor is mounted on the object that has to be temperature moni...
| Cet oscillateur simple n'utilise que quatre composants passifs pour faire clignoter une LED dans l'obscurité. Avec deux piles AA le circuit...
| This detector circuit uses just the Arduino Nano itself, no added sensor. Blowing some air from 30cm distance can be detected. It detects v...
| Oscillator circuit using only 4 passive components to make a LED blink when it is in the dark. Note: this is a normal LED, not a blink-chip...
| This 4th order audio filter design is based on four LDRs controlled by one LED. Driving the LED you can control the cutt-off frequency from...
| Voici un minuscule synthétiseur musical sérieux (c'est-à-dire, pas un jouet) qui utilise un Arduino Mini comme oscillateur numérique double....
| Music synthesizer with voltage controlled analog resonant filter and analog VCA. Double oscillator with wavemodulation and two loopable enve...
| This 2nd order filter uses four passive components. Frequency control with a current/voltage. Audio examples are given for synthesizer appli...
| Ce synthétiseur exploite des séquences binaires pseudo-aléatoires (SBPA) pour créer des sons percussifs et aigus, et d’autres effets sonores...
