Set Timer: OFF 5 Seconds (Test) 30 Seconds 1 Minute 2 Minutes 3 Minutes 4. Please remember that this product is not a toy and adult supervision is recommended when it is used in classroom and home settings. You may select 1, 2, 4, 6, or 9 clock faces to be printed on these time. Please inspect your Timer regularly and discard it safely if there is any sign of damage. With 'normal' regular use, your Sand Timer should last a long time – however, the inner glass tube will break inside the plastic casing if it is dropped heavily, thrown or purposefully mishandled. The inner is a glass tube filled with coloured sand. The material used in the outer casting of this Sand Timer is transparent acrylic with embossed plastic end caps. SafetyĪll Tink n Stink Sand Timers have passed a number of rigorous British Safety Checks. This level of consistency ensures routines and treatment plans are not disrupted and time management skills are reinforced. Therefore, when parents and teachers buy Sand Timers from Tink and Stink, they can be sure that the exact same timer is used at home, and in education and therapy settings. Our understanding of Special Needs and child behaviour is that consistency is vital. Our 2 minute Sand Timer will always be Bright Pink. The characters tell parents, teachers or therapists whether the timers are being turned over before they should be in order to gain or lose time. Our Tink n Stink Sand Timers feature our own Trademarked character embossed end caps. Therefore, please bear this in mind - we recommend our digital timers if you are looking for a timer with pinpoint accuracy. Our Sand Timers are rarely out but can have a 10% variance either way.

If you want to pause the timer, no problem, just press the 'pause' button and if you want to continue, press the 'resume' button. Just press start the 'start' button and this eleven minute timer will start. The timer switch in this project will keep the LED turned on for a maximum of approximately 2 minutes.Count down 2 minutes with ease using our much loved Tink n Stink Hourglass Sand Timer. This 11 minute timer is easy and simple online countdown timer clock with alarm. The time of discharge of capacitor through 10KΩ resistor and 100KΩ POT can be set by adjusting the variable resistor.Ī 1KΩ resistor acts as a protection resistor when the resistance of variable resistor is completely reduced. Set 2 Minute timer online and you will never miss the right time. When the switch is opened or button is released, BC547 will stay turned on due to the charge from the capacitor. A 2 Minute Timer will come in handy for you in a variety of cases, for example, if you like online games and want to track time or you play sports and the duration of the exercises or the time periods between them is important to you. R1 acts as the current limiting resistor for the LED. The 1000♟ capacitor will charge at the same time through 220Ω resistor.Īs BC547 is turned on and its emitter is connected to the base of BC337 through 12K resistor, it will trigger BC337 and it starts conducting.Īs the LED is connected to collector of BC337, it is turned on. Count down 2 minutes with ease using our much loved Tink n Stink Hourglass Sand Timer. When the switch is closed, the transistor BC547 is turned on. The circuit is very simple and self-explanatory. The timer is based on the charging and discharging of the capacitor in the RC network. The design of the timer switch is very simple.

It’s a transistor based electronic timer. If no key is pressed for a particular duration, the television or computer will automatically go to sleep mode where the device enters a low power consumption mode or may even be switched off. One of the best examples of a timer switch is the sleep mode in televisions and computers. The switch is turned on or off by the timer only after the preset time. Timer is a switch that is operated by a timer system. In this post, a simple timer circuit switch for light is designed that will turn on a high power LED for a particular duration. 1-48 of 486 results for '2 minute timer for kids' Price and other details may vary based on product size and color.
