So I have been working on an energy meter project for some time, I have implemented some nice functionality like voltage and current readings using differential amplifiers. I will be having a session to talk about these things on Wednesday Dec 4, 5 pm WAT. I would appreciate it if you @here were present, here is the link: https://app.livestorm.co/p/5507168f-31d9-45b5-9cf8-242db90bc4d8/live?s=79b27e95-039c-4ba8-8d9e-6be2a64e75c7

I'll be using Ltspice to explain how I went about measuring ac voltage and current using op amp in differential mode

hey guys, i will try to make a mini project for motion detection in my room and the temperature. i have a 830 point breadboard, arduino m-m cables and i use ESP-32S
DHT-11 for the temperature sensor and PIR rosfix hc-sr501 for the motion

it will be my first try at anything IOT, any ideas/tips and if its going to work? or i need more things?

Yes, it'll work, and the list of components you have is good enough to get started. Also, there are plenty of videos on YouTube to help you with these generic sensors (interfacing) with ESP32. If you get stuck, feel free to ask for help here with details about the issue you're dealing with. Looking forward to seeing your progress in the project and self-promotion channel!

why is your clock wierd? it should be pulsing no

Yes @undefined.elf fix the clock first look at your reference manual and see why it’s not pulsing perhaps look at apb and ahb registers

the thing is library should initialize the SPI peripheral

but that's not happening or something else overwriting my configuration

I am using esp32

ZacckOsiemo•12/2/24, 6:26 AM

Seems like it is using a different pin for clock read the library code see what pin is being used

if it was STM32 then I could rock

even though spi is not working

Sure, and meanwhile try to read blogs abt those sensors modules and watch YT videos. So by the time they arrive, you already have some know-how.

You see now, this is why you don’t use or build a Hal it’s easier to just write straight code for the functionality you need

ZacckOsiemo

Z

ZacckOsiemo•12/2/24, 7:34 AM

Because we maintain code more times than we write it, we need to optimize for that rather than for well written code
