Thank you all very much! Plenty of information for me to learn from here :-) So in the meantime here is what I needed up doing. I use TinkerCad for al...
@foxy Thank you for the help. I'll look at that document.
Seems like 12v power supplies are cheaper so I'm guessing a higher value resistor is in order.
OK, so after reading the ad a few more times I can understand that when they say 6v - 12v they are saying this because the kit comes with the resistor...
@spyder Thank you very much for the advice! I just thought it would be really cool to make gifts that just plug right into the tree lights and not h...
Thanks again my friends!
And this is exactly why I enjoy this forum and the support it offers a new electronics guy like myself! Thank you for the advice and direction. I agre...
Thank you very much for this and I'll look over the video. What might also help me is to better understand how to decide what kind of battery power ...
I just wanted to close this one up. I bought that other alarm that I linked above and wow it's loud! It's basically part of a home alarm system and th...
I think I'll bag that horn and pick up this one. It will work much better with the power that I plan to use in this project ->
@byron Yes I want the horn to fire for 1 sec once the Arduino comes out of sleep. Never really thought about just putting that in the loop. Pretty sil...
@byron The fan runs off of a USB plug so thinking it's only using 5volts. I think I'll use a fet to turn the power on and off but I need to figure out...
Sorry, when I meant "flip that switch" was hoping to replace it with something that I could control with an Arduino.
@zeferby I've been using the HiLetgo ESP-WROOM-32 ESP32HiLetgo ESP8266 NodeMCU CP2102 ESP-12E And some Wemos D1 Mini's to play around with.
Update on things so far. So since I'm so new at this I thought it would be best to break things down into little chunks and build up from there. First...
