A collection of 555 circuits using the 555 Timer as an astable oscillator with different duty cycles. We have seen in the last few tutorials that the 555 Timer can be configured with externally connected components as multivibrators, oscillators and timers, with timing intervals ranging from a few microseconds to many hours. As the 555 timer is one of our …

Circuit diagram of 555 RF driven audio oscillator. As shown in the figure, 555 and R1, RP1, C1 constitute a controllable audio oscillator, f = 1.44 / (R1 + 2rp1) C1. The frequency of the parameters shown in the figure is between 600Hz and 20kHz, which can be selected by adjusting RP1. Whether the oscillator oscillates or not depends on the level of the 4-pin reset …

The advertised maximum frequency of the 555 is about 360 KHz. This Oscillator will sometimes work at a slightly greater frequency. This circuit is very similar to the first circuit. Replace the 10 uF electrolytic with a 1 nF disk capacitor. This is a very small capacitor. The marking on it says 102. Add a 100 nF disk capacitor between pin 5 and ground.

Recently I have been building optical square wave oscillators using 555 chips wired in astable mode and using a CDS resistor in the circuit to control pitch (frequency), these circuits are connected to speakers or an amplifier and used as audio noisemakers. What I now want to build is a circuit that is powered by 9V dc and uses one 555 IC (or ...

Circuit Description. This is an adjustable frequency , 50% duty cycle astable multivibrator using the 555 timer IC. An approximately 50% duty cycle is achieved by using a single timing resistor. In contrast to the conventional 555 astable circuit, which uses a discharge resistor to the discharge pin and additional resistor to Vcc for charging, this circuit has almost symmetrical charge and …
