Sure, here's the corrected version of your text:
So my end project is a smart house and I have my first show tomorrow. I made a project with some friends, ChatGPT, and nice people here but I have a problem.
This is what my house does:
- Your heart rate increases when you wake up. You can choose a wake-up time, for example, between 7:00 and 12:00. If you have an elevated heart rate during this period (the moment of waking up), you can calmly let an alarm or alert go off. The curtains will automatically open, the room lights will dim, and a cup of coffee will be ready for you. I also want to hang a sensor on the door so the lights turn off when I leave the room.
My code works partially. If you have some time to help me, that would be awesome.
Fix 1 (probably won't take long):
When my BPM is above 155, my lights go on and my buzzer plays music. When I press my button, the sound stops like a snooze button, and my lights stay on (that's good). When my PIR sensor detects movement for the first time, it shuts off the LEDs as it is supposed to. But when I walk in the second time, my code needs to reset to the original state, so if my BPM rises above 155 again, the buzzer plays. However, it won't do it.
Fix 2 (would take a while):
When my BPM rises, a water pump that I connected to a battery and relay needs to be on for 1 second (connected on Pin 11) and then turned off until I walk in a second time like in Fix 1 (the reset).
I also have a DC motor connected to an L293N with (IN1=Pin 12, IN2=Pin 7, IN3=Pin 1) and a potentiometer on pin A1. It just needs to turn for 2 seconds after my BPM rises above 155 BPM (so I can fine-tune it with the potentiometer).
