Hi,
I'm kind of a new comer when it comes to electronic, so I tried to illustrate, in the easiest way possible, what I'm trying to achieve.
I wanted to have your opinions and advises.
Please, let me know if I'm missing something before buying the parts. (I already have the ESP, the SR and the buzzer actually - but I was more thinking of resistance and capacitors)
- So the goal, is to detect a movement and when it does, to send a sms via the ESP which will also trigger the buzzer. As you can see one of my main problem is: The ESP is 3.3v, the Buzzer is supposed to be 12v.
How can i go from 3.3 to 12 ? I have no idea...
- In term of the ESP, I just want to make sure, can I, with some code, order the ESP to trigger the buzzer ?
- For the power source, I was thinking of this:
https://www.amazon.ca/XCSOURCE-Battery- ... =3.7v+lipo
It's small, perfect for the ESP, and should provide enough current (800mAh) right ?
Thank you very much !
