Waveshare Dust Sensor, not showing data on Blynk App

Hi! In class, we have a final project assigned to us. We chose to build an air quality device, similar to the air owl quality. We are using an arduino 101 board, and coding through arduino. The only thing we did not do according to the guideline, was get the dust sensor listed on there. The dust sensor is no longer sold, therefore we ordered a waveshare dust sensor. We followed a guideline, posted by a user (link above). We have managed to get everything set up and connected, but the blynk app does not display the values of the dust sensor. Is the issue the dust sensor, the code, or the app? What should we do to fix it?

Thank you!

Debugging process is always the same.

  1. Make sure you can read the sensor without Blynk.
  2. Make sure that Blynk minimum sketch works with your hardware
  3. Start merging 2 sketches, make sure to use timers, keep the void loop clean, etc.

Hello, sorry for the late reply. Thank you for your response, and we have been doing a lot of debugging. Only issue that is left, is I don’t know how to get the adafruit neopixel v2 led to work. Do I solder it? It does not say how to get it to work.

Sounds like a question for that hackster project author… or here - https://learn.adafruit.com/adafruit-neopixel-uberguide/the-magic-of-neopixels

We are the Blynk forum and no soldering is required for Blynk App, Library or programming commands :stuck_out_tongue:

Besides, solder doesn’t make a neopixel “work”, soldering is a physical connection process, nothing more magical than that.
