Relay Timer Answered
i am currently engaged in a project where i need to create a count down timer relay controller. i was thinking of using a digital alarm clock as part of my goal is to have the display visually counting down, but i don't know of any that have a count down feature. i want the timer to power a relay to turn a string of IR emitters on for several seconds. i have a digital kitchen timer that counts down, but im not sure if it will work. i would like to use the power to the buzzer to activate the relay but there is no stable current there, it only Emits several beeps in quick succession(when i meter it, it comes out to about . volts). this is why the alarm clock would be better. i was hoping to use an electromechanical relay but i don't think it will work. does anyone know of another relay that will trigger with this kind of input?
