When I'm using configurePin and readVoltage for analog pins using an Arduino Leonardo board I'm getting the following errors in R2023B: "specified Key type does not exist" and "the first input must contain a multiple of 2 elements.." See code snippe...
Connect three wires to the Arduino board. The first goes to ground from one of the outer pins of the potentiometer. The second goes from 5 volts to the other outer pin of the potentiometer. The third goes from analog input 0 to the middle pin of the potentiometer. 从Arduino 板子接出 3...
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 is in the public domain. */ 功能:读取模拟引脚A0上的电压值,并将其转换...

I'm trying build and deploy simulink models to Arduino Uno using the "Simulink support package for Arduino hardware". I need to change the pin mode of pin "A0" to output and wirte to it. I know it's possible using the "Matlab support package" but the "Digital Output" block in the ...

while avoiding problems along the way.Arduino boards connect to digital peripherals through the I/O pins I described in the February column. Much of the Arduino's popularity, however, comes from its ability to sense and control the real world through its analog input and output pins, using si...
If you wish to use more than one magnetic sensor, make sure you connect their ADC pins to different arduino pins and follow the same idea as above, here is a simple example: MagneticSensorAnalogsensor1=MagneticSensorAnalog(A1,14,1020);MagneticSensorAnalogsensor2=MagneticSensorAnalog(A2,14,1020...
- You can use your UNO as a serial device, however, your UNO puts out 5v at both the tx and rx pins. Some sources state that the ESP8266's GPIOs are tolerant. tx and rx are not. Use voltage dividers and diodes or some other magic. Besides, if you have to use an Arduino for ...
