sauravgoswamiIf you are using a single LED then you can use an OR gate or a multiplexer,and if you are using individual leds then there is no need of that...

hello I want to OR three 555 outputs for example, I have a LED that should be on when ANY of the 555 outputs (pin 3) is on do I...

godfatherWhy not you use Microcontroller is there any restriction?no I just find it easier if it's possible with one or two 555, if it's possible otherwise I'd need to get...

godfatherSo you want to monitoring the Input Pules Continue?yes summarizing the output should go high if the input is steady high or low for more than 15 seconds then the...

hello I want to do something similar to a missing-pulse-detector, but I want it to detect also steady signals so I basically want to output high when the input is...

what actually worked was that: #-Link-Snipped-# (I later changed the voltmeter by a LED and it lighted correctly when it should)

hello thanks for your answer I have an explanation for that I'm using a 120V AC though a diode bridge, so it becomes 120V DC with about 170V peaks I...

hello I'm trying to auto-discharge a capacitor when it's charged using LM311 (voltage comparator), but although it worked on a protoboard while I was testing with a 12V PSU it's...

hello could someone please help with that circuit? #-Link-Snipped-# I want to auto-trigger SCR (U1) when the capacitor is charged to a certain level my understading is (I'm new at...
