![]() 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.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.A little light soldering is required to put it together for breadboard use.Where can you use this Timer? As web window If you want to turn the device on by hand, you can also activate the TPL by pressing the onboard tactile switch (or wire your own switch to the Delay pin) See? Your power problems just got solved!Ĭomes as a fully assembled breakout board with a TPL5111 chip, all components on-board, and some header. While the TPL5111 is running (but the remainder of the project is de-powered) the current draw is about 20uA (according to our Monsoon Power Meter). In your project's code or design, just make sure that it sets the Done pin high once it is completed with its task. Finally, select a signal pin from your project to the Done pin. Then, connect VDD up to your 3-5V project power supply, and then your project's enable pin to the Enable pin. First, set your desired delay but adjusting the on-board trim pot: all the way to the left is once-per-100ms and all the way to the right is once-every-2-hours. The TPL5111 breakout is best when you have an enable pin you can control, the TPL5110 is best when you are able to 'break' the power input line to place the TPL5110 between the power supply and Vin. We also have a TPL5110 breakout, which rather than setting an enable pin high/low, connects and disconnects power. ![]() If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low. ![]() Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. The Adafruit TPL5111 Reset Enable Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Or, use a 555? Ugh, the options aren't that great. So what should you do when it's time to turn around and make that project of yours run on a battery or solar? Sure you could try to hot-air that regulator off, or you could jerry-rig a relay. Especially when price and usability are the main selling points. ![]() With some development boards, low power usage is an afterthought. TPL5111 Low Power Timer Breakout Adafruit 3573
