Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor. Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. This example code
Connect the three wires from the potentiometer to your board. The first goes to ground from one of the outer pins of the potentiometer. The second goes to 5 volts from the other outer pin of the potentiometer. The third goes from the middle pin of the potentiometer to analog input 0. 连...

This project provides a minimal HTTP-based firmata controller for various hardware, especially the Arduino. This, in turn, extends the user's control and ability to monitor the hardware using platform-independant URL requests. Support list: Digital Pins Analog Pins PWM Servo This is just a few ...
Place the DHT library folder your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE. Reef complete PCF8591 Analog input and analog output to digital converter with i2c bus. I try to simplify the use of this IC...
One possibility is, of course, toconnect an Arduino to the Raspberry Pi, since it also has analog IO pins and can, therefore, read out those signals without ADC. How this works is described in detail in the linked tutorial. The disadvantage of this, however, is that on the one hand, ...
I really looks like the C3 just doesn't have it's GPIO/ADC pins mapped. The first 22 GPIOs point to Analog channel 0. And this A/D channel does indeed work as expected. so the missing peaces are some defines in cores/esp32/esp32-hal-gpio.c#L49 something like #elif CONFIG_IDF_TA...
