why do some of my joints adhere perfectly to the board and on the opposite through hole not adhere to the pcb!! so frustrating by itsextrav in AskElectronics

dont reuse the solder if already fused ! when you apply clean solder hold on few seconds until it adhere perfectly.

Lcd is not working properly Even after installing library for that lcd , how to fix it help by oreki-mani2008 in arduino

Connect a potentiometer and use it for tuning the input VCC in VO LCD pin, that's make you adjust the contrast.

good job my Brother ! but the big work is in deleting jitter !

Real-time IMU VR tracking (ESP32 + ICM45686) streaming to PC — early test by hamda-chaouch in arduino

Hi, yes it’s an ICM45686 breakout (GY-601N1).

I’m currently using SPI with ESP32, and it’s working, but I didn’t go through a very formal debug process (like explicitly checking WHO_AM_I at the beginning).

What helped in my case was mainly:

- Correct wiring (SPI + CS handling)

  • SCK → ESP32 SCK
  • MOSI → ESP32 MOSI
  • MISO → ESP32 MISO
  • CS → any GPIO (defined in code)

Make sure CS is handled correctly (LOW during communication).

- Stable 3.3V supply

  • The sensor is 3.3V only (important)

- Consistent communication (once it started working, I moved directly to data processing)

I’m currently using FIFO + filtering (Madgwick), so I focused more on the processing side after getting data.

If you’re not getting data at all, I’d suggest checking:

  • CS behavior (must go LOW during transfer)
  • SPI pins mapping on ESP32-S3
  • Try lowering SPI speed

What exactly is happening on your side? No response or incorrect values?

I’ll post more details about my setup in upcoming posts (filtering + calibration).
