Figure 6 C2 charge injection first-pulse fix modified for bipolar 555 square wave generation. Stephen Woodward’s relationship with EDN’s DI column goes back quite a long way. Over 100 submissions have ...

555 triangle generator with adjustable frequency, waveshape, and amplitude; and more! More gated 555 astable multivibrators hit the ground running; Inductor-based astable 555 timer circuit; Tags 555 • ...

My boss has a pathological hatred of the 555. He told us it was instant termination if he ever found a 555 in any of our designs. We have been unable to extract from him the basis for his hatred ...

It’s an excellent way to learn about both PWM motor control and the use of 555 timers, all with a very low parts cost and readily available components. We’ve seen such setups before, used as ...

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 ...
