So I suggest you draw the full circuit and post it so I and others can make suggestions before buying parts. You will also need to include some control logic - to do the sequencing, light the LEDs, etc. Do you intend to use Thumb Wheels to set the seconds also? Low Profile Rotary Dip Switches (with Extended Shaft) 'ĭoes this switch convert from decimal to BCD?Īlso, if you include a seconds counter, it will need a Modulo 6 counter. 'For the Thumb switches, I'm actually going to use ITT Industries - RTE1001N13's. The seconds counter will need a seconds clock which could be a 555 or, if you want better accuracy, a crystal oscillator as above. If so, the minutes counter will be driven by the 'carry out' of the seconds counter. Besides, you said that you may include a seconds counter.

It would be better to use a crystal oscillator and binary dividers. 'For the one minute timer, should I use a 555? or is there a better way?' For example, the half 4002 gating could be implemented using two halves of a 4001 and a third of a 3 input NAND IC (if this proves to be more economic once the overall parts count is considered). A timer is a device that measures a time interval and signals its end. BUT, before you purchase, you should do the full design as it is usually possible to optimise once you have the full picture. Timer 1 minute You can use the online timer on to measure a time of one minute. After see the question if i want answer that question means click 'show answer' button. What is a timer A timer is a device or tool that counts down a set amount of time, often used to measure or regulate the duration of an activity or event. In my project ,I have list of questions, for every question have three option answers. If this has already been discussed, I apoligize, I searched for about 20 minutes before posting this. An online Timer for measuring the duartion of activities or events. If someone has a really simple circuit, I would appreciate it. I've thought about just using electromechanical relays, but want a smaller package that can run on batteries. Does anyone have a better way? I don't have access to any type of PIC writing equipment, so that is out of the picture. Like I said, I havn't done any electronics work for about 6 years (I'm a power systems engineer). I was thinking of using two BCD-countdown timer chips and some 74xx logic to pull the 1 min left and 0 readings. 1 hour 35 minute timer will count for 5700 seconds. To start the 1 hour 35 minute timer, simply click on the Start button. The reset button is pushed an then all lights/buzzers are off awaiting next start press. The timer has already been set for 1 hour and 35 minutes from now. When the 5 minutes is up, the red light comes on (and optionally, the buzzer turns on). (and possibly a very short burst on the buzzer). When the start button is pressed, the green light lights up.Īfter 4 minutes, the green light shuts off and the yellow light turns on. The way that I would like it to work is as follows: I would like to have a final product of a box with three lights (Green, Yellow, Red), two buttons (Start, reset), some way to set the time (thumb-wheel switch), and possibly a buzzer (with a switch to kill it). It's been about 6 years since I took my electronics classes and I was looking for some help.

This code sets the prescaler to 1024, as slow as you can get. So, cycles is NOT less than RESOLUTION - 1, therefore it was more than maximum.

Select all instances of Big Timer in the search results RESOLUTION is set to 65536 because Timer1 is a 16bit timer.
