Adafruit_ADS1X15 VS ESP32-BLE-Keyboard

Try this: example

For analog input, probably something like this I²C ADC: https://www.adafruit.com/product/1083 which supports 4 digital channels. It connects to the SDA and SCL pins on the Arduino. You'll need this Arduino library to use it: https://github.com/adafruit/Adafruit_ADS1X15

Given that the code is already pretty much identical to one of examples (https://github.com/adafruit/Adafruit_ADS1X15/blob/master/examples/singleended/singleended.ino), it should work.

Is there any reason you couldn’t use the Adafruit library? https://github.com/adafruit/Adafruit_ADS1X15

How you do the code will depend on which library you use for the ADS1115. I didn't see anything brain-damaged in the Adafruit library, so it should work for you. I'd run it in single-shot mode, since you'll be scanning the 4 inputs; it only runs continuous mode on a single channel. Their Doxygen doc sucks... look at the single-ended example instead. It's dead simple to use. A gain of 4 or 8 is your best range, then simply multiply the result by 10 (because of the 0,1 ohm resistor) and you'll have the current.

I am trying to get started with the bluetooth keyboard example for ESP32. using the example, it throws the error: "Compilation error: 'BleKeyboard' does not name a type" I have tried to compile this in Arduino 1.8 and 2.2.1 and on multiple computers. all fail to compile. I even tried to downgrade the ESP32 package to 2.x to no avail. What am i missing here?

For example: https://github.com/T-vK/ESP32-BLE-Keyboard

I like using the ESP32C3. If you don't need a lot of pinouts, the Seeed Studio XIAO ESP32C3 ($9) is awesome for emulating a Bluetooth Keyboard using the https://github.com/T-vK/ESP32-BLE-Keyboard library. Thanks to the Community members who made me aware of the BLE library.

this library is great

It'll be much easier and cheaper if you used a ESP32. Example https://github.com/T-vK/ESP32-BLE-Keyboard

From the library's BleKeyboard.h file, I think the main problem I have is that some keys are just "KEY_" which are type uint8_t.

If you're trying to build a totally custom thing, it looks like there's a library to use the ESP32 as a bluetooth keyboard. https://github.com/T-vK/ESP32-BLE-Keyboard

ESP32 with this BLE keyboard library is an option.

Keyboard Library: https://github.com/T-vK/ESP32-BLE-Keyboard/releases/tag/0.3.0

With this library it's pretty simple - have you tried it ? https://github.com/T-vK/ESP32-BLE-Keyboard
