I followed this video: https://www.youtube.com/watch?v=-xK0B_bM-yk and made these circuits:
And they work as I want them to. I have 2 pushbuttons so when one or both of them are being pressed, the corresponding LED/s on the receiver side light up, and when one or both of the pushbuttons are no longer pressed, the corresponding LED/s turn off (no latching on the HT12D decoder side because TE is constantly transmitting as it's hooked up to GND).
My question is - how can I (since battery life is important in my case) enable TE only when one or both of the buttons are pressed or stop being pressed. My goal is to not transmit all the time because I want to save battery. And also I don't want the LEDs to latch upon the receiver side so when the pushbutton/s stop getting pressed, I need the LED/s to turn off. What would be the simplest and most space-efficient (in terms of SMD components) way to do this?
