当您打开Arduino IDE时,为了正确设置IDE,请转到:工具》端口》……,然后选择带有Arduino Uno名称的端口。 对于Windows,它应该类似于“ COM4(Arduino/Genuino Uno)”。 对于Linux,它类似于“/dev/ttyACM0(Arduino/Genuino Uno)”。 ,对于操作系统“/dev/cu.usbmodem146
Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset bu...
将UNO板通过USB先插入电脑USB,打开串口监视器,设置为“115500”、“NL和CR”,输入“AT”,可以在串口监视器中看到“OK”。说明ESP-01S连接成功。 AT命令 注意:ESP-01S的RX和TX连接分别连接到UNO板的pin0(RX)和pin1(TX)。这里一开始容易不理解,其实这里ESP-01S只用到了UNO板上的USB转串口芯片,你可以理解为ESP...

Uno's ADC resolution is 10 bits, which means that it can distinguish the value between 0 and 1023. Reference voltage: The reference voltage of Arduino UNO is usually 5V, which means that the maximum input voltage of ADC is 5V, corresponding to the maximum value of 1023 for ADC output.2...
