- Va_Tech_EE commented on Va_Tech_EE's instructable Car Heads Up Display (Arduino + ELM327)
Thanks! I really wanted to have an ESP32 on-board to serve up a webpage (via WiFi Access Point) with my car's speed/rpm values updated real-time. This would allow passengers who can't see the HUD still access and monitor the data. However, the ESP32 can't use all of it's pins when in WiFi mode, so I needed a Teensy to drive all the LED signals and log the data on an SD card.

It's much easier to use dedicated libraries for Python <--> Arduino communication. For example, https://github.com/PowerBroker2/pySerialTransfer and https://github.com/PowerBroker2/SerialTransfer. SerialTransfer.h is installable via the Arduino IDE Libraries Manager and pySerialTransfer is pip-installable. With these libraries, you can easily and reliably transfer ***bytes, ints, floats, and even structs***!!

For a more robust interface between your Arduino and ELM327, you can use ELMduino.h --> https://github.com/PowerBroker2/ELMduino. It's installable through the Arduino IDE's libraries manager and comes with examples.

You can communicate much more easily and reliably if you use the pip-installable package pySerialTransfer. The package is non-blocking, easy to use, supports variable length packets, automatically parses packets, and uses CRC-8 for packet corruption detection.

You can communicate between Python and an Arduino a lot easier if you use libraries. On the Python side, you can use pySerialTransfer (pip installable). On the Arduino side, you can use SerialTransfer.h (installable through the Arduino IDE).pySerialTransfer: https://github.com/PowerBroker2/pySerialTransferSerialTransfer.h: https://github.com/PowerBroker2/SerialTransfer

DFRobot's library for the DFPlayerMini is a terrible and inefficient library. If anyone want's a faster and simpler library to use with this module, I suggest using this one: https://github.com/PowerBroker2/DFPlayerMini_Fast. You can also download and install through the Arduino IDE's Libraries Manager (search "DFPlayerMini Fast").

- Va_Tech_EE commented on Va_Tech_EE's instructable Gyroscopic Arduino Head Tracking UnitView Instructable »
I have no idea what you're talking about. What do you mean it doesn't work on an UNO? If you're trying to do headtracking on a single Arduino, use the HeadTracking_Gyro_TEST.ino code.
- Va_Tech_EE commented on Va_Tech_EE's instructable Gyroscopic Arduino Head Tracking UnitView Instructable »
That's very simple. Just use the softSerial library instead of Serial2 to transmit data (this will dictate which two data pins you hook up the XBee to the Nano with). Everything else a can stay the same. You will have to look up which pins are SDA and SCL on the Nano, though (this dictates how you hook the gyroscope to the Nano).

Ahh, I see. Arduino handles floats like any other C++ microcontroller. When you divide by 10, just write it as 10.0 and make sure the variable the value is being stored in is type "float"
- Va_Tech_EE commented on jiangshan00000's instructable Make one PM2.5/air quality monitor with Arduino UNO
Sorry to say, but I believe there is a bug in your code!If you look in the sensor datasheet, you do not construct an int out of the low and high bytes of PM10 and PM2.5 like in the code you posted. The datasheet says to do this instead:PM2.5 value: PM2.5 (μg /m3) = ((PM2.5 High byte *256) + PM2.5 low byte)/10PM10 value: PM10 (μg /m3) = ((PM10 High byte *256) + PM10 low byte)/10datasheet link: http://inovafitness.com/software/SDS011%20laser%20PM2.5%20sensor%20specification-V1.3.pdf PM10 value: PM10 (μg /m3) = ((PM10 high byte*256) + PM10 low byte)/10

Does this lib live in a GitHub repo by chance? I'd be interested in a link to it if possible.
