Need help with timing circuit for ballistic sensor

I built a project using an Arduino microcontroller to manage high speed photography of an air rifle shooting targets like balloons. I have a contact switch on the trigger. When that feeds a logic 1 into my Arduino program, I tell the camera to fire…

Long Accurate Time Delay

In an exam today I was asked to design 2 circuits that would keep an output turned on for 10 minutes. I used a 555 Timer and a PIC, but neither are the best solution if the time delay needs to increase. So what other options are there for creating…

Flip flops with multiple clocks

Assume I have 2 flipflops FF1 and FF2 which are driven using multiple clocks. What might be the possible violations that we would come across? I was asked this in an interview for which I answered telling the difference in skew or the clocks would…

Electrical Device Up-time

I have to measure the up-time of devices such as refrigerators and geysers and store that data in the database. What is the easiest way to measure this up-time? I read that timing circuits could be used for the same. But there was no clarity on this…

Hold-time Violation and timing diagrams

I was wondering what the output of capturing flop looks like, if there is a hold time violation from capture flop. Can anyone explain with a timing diagram?

time counting at -50°C

I'm designing a small slow control system with ATMEGA2560. This board needs to measure temperature, voltage(0~4V), magnetic field using sensors, and monitor the digital status(High or Low) of some wires. Whenever each measurement happens, then…

How to draw a timing diagram for CSE 120 class

I've never done a timing diagram before. So I basically have no idea what I'm doing or what the question is asking. I would appreciate any help! Thank you.

Circuit to shut off power after a short time of turning on

I've got a 3V button battery driving an led and a trembler switch functioning now. However, the sensitivity of the switch is giving me trouble because I need it to remain open when at rest in a horizontal and vertical state and only open when set…

Use Cellphone Vibrating motor in Mouse; on for 3sec off for 3 minutes

I have electronic maintenance experience but it dates to 1985 (last use). I can still solder well but I have forgotten all the electronic theory I once new except for VERY basic stuff. So assume I'm a newbie. I would like to install a micro…
