LED will be ON initially (OUTPUT PIN 3 LOW), as soon as we press push button (trigger the 555 via TRIGGER PIN 2), the timer will start, and LED will become OFF (OUTPUT PIN 3 LOW), after the calculated time duration, PIN 3 will again become LOW, and LED get turned ON. So we have calculated OFF time above, means after the calculated time LED will be turned ON. We should note here that we have used LED at reverse logic, means when OUTPUT pin 3 is low, LED will be ON, and when OUTPUT is HIGH then LED will be OFF. Similarly to create a 10 minute timer we would be changing the resistor value to 545.4 k ohm.Īs per above calculations, for a 15 minute timer circuit, we need the value of resistor to 818.2k ohm. So to build a 5 minute timer circuit, we would be simply changing the resitor value to 272.7k ohm in above given 1 minute timer circuit. We can easily calculate the resistor value for 5 minute, 10 minute and 15 minute timer circuit: So to build 1 minute (60 seconds) timer we need resistor of value 55k ohm and capacitor of 1000uF: In monostable mode, the duration for which the PIN 3 would remain HIGH, is given by the below formulae: We need to set 555 timer in Monostable mode to build Timer. All we need to change the value of Resistor R1 and/or Capacitor C1. We can use this property of 555 timer to create various timer circuits like 1 minute timer circuit, 5 minute timer circuit, 10 minute timer circuit, 15 minute timer circuit, etc. It means for some time output pin 3 is HIGH and for some time it remains LOW, that will create a oscillating output. It will start when someone opens the email / invite (they can restart it with the play button).As the name suggest 555 timer is basically a “Timer”, which create an oscillating pulse. Add it to an email or to a meeting invite (via Insert Picture).Use it in Excel or Word (via Insert Picture) as part of a quiz or form – re-starts on click.The timer restarts when you refresh the board (so simply refresh it each time you start on the next list) Upload it as a cover image to Trello – possibly as the top item on a list.But if the deck is refreshed the timers start as you click to the next slide And the page needs to be refreshed for it to work. Load it into Jamboard for different pages.Use it with PowerPoint and OBS as a drone breakout participant in Zoom and Teams.Add it as a source in OBS in your webcam to help people keep to time.Insert it into a webpage, to control an activity.Paste it into Microsoft Whiteboard as a means of timebounding activity – simply click to stop and restart.Use it within Powerpoint or Google slides as a timer for slide guided activities, or for quizzes.And then upload it via the application’s own image import facility. Other applications sometimes work better if you save the image. These copied images you can paste directly into some applications, and they work immediately. Simply right-click the timer image and select ‘copy image’ or ‘save image as …’ as appropriate. Outside of meetings, use it as a personal time manager for particular task allocations.Or ask people to load it up themselves (from the link) to keep to time in breakouts. #7 minute timer software#You can also share directly as a window in meeting software.Or with anything else you share via a screen in meeting software Use on any shared screen to sit on top of slides, video, web pages, people speaking, documents.Where can you use this Timer? As web window
