The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. ... This type of circuit is well suited for car alarms if you substitute ...
This is a small size led flasher built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, dark room timer, memo-reminder or other similar ...
Therefore, the duty cycle of the 555 IC’s square wave is the determining factor for the LED fixture’s brightness. Pretty slick! He used a widely available and inexpensive D718 power transistor that is ...
This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2 ...
[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transis… ...
