I have a basic one-shot timer circuit (shown below in schematic). If I press the button, it brings pin 2 low and triggers the timer one time for a period which with my cap is about 5 seconds.
Use IR Sensor To Drive Trigger Low
What I'd like to do now is replace the pushbutton with a specific IR sensor which I have. I got it from AdaFruit and you can see the details at: https://learn.adafruit.com/ir-sensor/testing-an-ir-sensor
This particular IR sensor has 3 pins. You supply 5 volts on pin 3, ground on pin 2 and then when you fire the IR remote at the sensor it says that pin 1 is driven low. I have successfully created the circuit which will light an LED with that circuit also -- you can see that circuit below (it's an image from the adafruit site).
How Do I Use This Circuit? How can I hook this second circuit into my first one so that it will replace the push button and drive the trigger low?
Will I need to implement some kind of gate using a transistor?
