Category: Other Circuits / 555 Timer Circuits Views: 2019 Rank: 0 Using a CMOS version of the 555 timer, this circuit can be used to control the speed of a motor by adjusting the duty cycle of the pulses sent to the motor. visit page.
Related circuits The circuit in Figure 1 produces timing signals with a sound like that of a mechanical metronome. IC1 is a 555 timer that oscillates at approximately 3200 Hz. The two 3-kW resistors and the 0.047-µF capacitor set the frequency. IC2 divides the frequency of IC1`s output by 2. IC2 produces a... Car alarm circuit using 555 timer 555 timer produces a guaranteed delay, allowing the driver to deactivate the alarm and the elimination of a control switch vulnerable outside. Battery charger indicates rate of charge A single LED indicates whether the battery charger in Fig 1 is delivering a trickle charge or a fast charge. During fast charges, the LED stays lit continuously because IC2`s FASTCH output sinks dc. During trickle charges, the LED flashes because D1 and Q1 enable the 555 timer. The timer is an... This infrared remote control timer can be used to turn an appliance on/off for a period of 0.11 second to 110.0 seconds. The circuit comprises two sections, namely, the transmitter section and the receiver section. Fig. 1 shows the IR transmitter section. The astable multivibrator NE555 (IC1) is... Here is a Simple Circuit to give a Flashing LED, With a "Rising and Falling" Brightness. It Uses the Sawtooth waveform from pins 2 and 6 to create the rise and fall. The Resistor and LED on Pin 3 are Optional. The 10K Potentiometer give a reasonable range of Speed. 555 Timer Forms Simple PWM Motor Controller Using a CMOS version of the 555 timer, this circuit can be used to control the speed of a motor by adjusting the duty cycle of the pulses sent to the motor. These circuits provide a means of altering the YELLOW output of RED / GREEN type two colour light emitting diodes. These circuits use the LM555 timer chip. An op-amp IC (741) amplifies the audio signal from MIC1, and R12 controls its gain. Audio is fed to the oscillator circuit Q1 and related components. D2 is a varactor diode. Audio fed to D2 causes FM of the oscillator signal. 2-channel servo motor controller chip - SUD1010e (PWM 50hz)
