Category: Other Circuits / 555 Timer Circuits Views: 3342 Rank: 0 I don`t know why, but people like blinking lights. You see LED chasers everywhere, in TV shows (Knight Rider), movies, and store windows. This schematic is my version of a simple 10 LED chaser. There is no 555 timer used because at my local electronics store they are over $4 Cdn. Instead, an oscillator made up of two sections of a 4011 NAND gate is employed. This chip is very inexpensive and extremely common. visit page.
Related circuits The unit provides a square-wave output that is rich in harmonic content. The circuit"s output frequency can be varied from 50 Hz to 15 kHz. The heart of the circuit is a 555 astable connected in its equal mark/space mode. The frequency is controlled by potentiometer R2 and capacitor Cl. Binary Counter using 555 and 4042B In this circuit diagram, an NE555 timer is used as a pulse generator producing pulses at about one-second duration. This is governed by the timing components connected to pins 2, 6, and 7. If the 100µF capacitor connected on pins 2 and 6 were reduced to 47µF, then the counting pulses will be... Delaying Pulse from 555 circuit The circuit below illustrates generating a single positive pulse which is delayed relative to the trigger input time. The circuit is similar to the one above but employs two stages so that both the pulse width and delay can be controlled. When the button is depressed, the output of the first... Infrared beam barrier/ proximity sensor This circuit can be used as an Infrared beam barrier as well as a proximity detector. The circuit uses the very popular Sharp IR module (Vishay module can also be used). The pin nos. shown in the circuit are for the Sharp & VIshay modules. For other modules please refer to their respective... The 555 circuit below is a flashing bicycle light powered with three C or D cells (4.5 volts). The two flashlight lamps will alternately flash at a approximate 1.5 second cycle rate. Using a 4.7K resistor for R1 and a 100K resistor for R2 and a 4.7uF capacitor, the time intervals for the two... Adjustable flashing LED with 555 Use a 555 timer IC as the (resistor controlled) frequency source, choose component values to run at 2 x desired flash rate - get the data sheet for this part, it`s pretty comprehensive. Drive transistor 1 from Q, drive transistor 2 from Q or /Q via a switch. Run the whole thing from +5V. If you... IR Remote Control Extender Circuit (Mark 3) IR appliances use pulses (control signals) sent over a modulated IR carrier wave. The carrier wave may be modulated at various frequencies, 36-38KHz being the most popular.Some Satellite receivers use even higher frequencies than this. The IR1 remote module receives an infra red signal and... Integrator multiplies 555 delay Long delay times can be derived from a 555 timer with reasonably sized capacitors if an integrator circuit is used.
