NE555 melody circuit

Timing has an integrated circuit made ??with N555 hundreds of years in the market all the electronic equipment in the shop a popular integrated See here for a detailed knowledge of Turkish. Circuit as musical notes can give a voice to the series resistance values ??button is pressed, left to right according to the RE, DO, SI, LA, SOL, FA etc. Instead of going fixed resistor adjustable resistor (potentiometer) using different voices are granted

In fact circuit “Square Wave Oscillator” resistance frequency of notes determined according to each note separately frequency there DO-200HZ, RE-246HZ, MI-261HZ, FA-293HZ, LEFT-329HZ, La-349HZ, SI-392HZ, of course, the piano like this in exactly clear note sounds dead end, but the development of your hand skills, experience an ideal circuit

Working with 12 volts DC circuit draws very little current. In the market usually four-legged mini button has two legs can use the button press left will be the type pressed batch short-circuited when left open-circuited measure the tool’s “20ohm & buzzer,” stage in the end to find you can measure measuring instrument probes to the correct terminal contact and press the button when a shrill voice revenues .

    Speaker DC Protection Circuit Delayed and LED alarm

    The circuit can be delayed and led excitation speaker dc protection circuit.A current of approx. 70mA. The appropriate value for the high voltages are selectable Rs resistance.

    For example: Amplifier 2x24Vac with the feed from the same place, we can get this circuit.Aim will be about how to find the value and power of direncimizin 34Vdc.

    Melodie Schaltung NE555

    Timing hat eine integrierte Schaltung mit N555 Hunderten von Jahren auf dem Markt alle elektronischen Geräte im Shop eine beliebte integrierte Siehe hier für eine detaillierte Kenntnis der türkischen. Schaltung als Musiknoten können eine Stimme zu den Serienwiderstandswerten geben ?? Knopf wird gedrückt, von links nach rechts entsprechend dem RE, DO, SI, LA, SOL, FA etc. Anstelle des justierbaren Widerstands des festen Widerstandes (Potentiometer) unter Verwendung des anderen Stimmen werden gewährt

    In der Tat Schaltung “Square Wave Oscillator” Widerstand Frequenz von Noten bestimmt nach jeder Note getrennt Frequenz dort DO-200HZ, RE-246HZ, MI-261HZ, FA-293HZ, LINKS-329HZ, La-349HZ, SI-392HZ, natürlich Das Piano klingt in genau dieser klaren Note tot, aber die Entwicklung Ihrer Handfertigkeiten, erleben Sie eine ideale Schaltung
