void setup() { pinMode(3, INPUT_PULLUP); }This can be useful when you don’t want a pin to be floating, e.g. when you connect a button to a pin.Note that the analog pins can also be used as digital pins, using the aliases A0, A1, etc. The exception is the Arduino Nano’...
NodeMCU has weird pin mapping. Pin numbers written on the board itself do not correspond to ESP8266 GPIO pin numbers. We have constants defined to make using this board easier: staticconstuint8_tD0 =16;staticconstuint8_tD1 =5;staticconstuint8_tD2 =4;staticconstuint8_tD3 =0;staticconst...
在nano组装好以后,厂家往ATMEGA328P的Flash空间内写入了Bootloader,写入Bootloader的空间是单独预留的,芯片手册标注是:Boot Flash Section(ATMEGA 328p预留了2KB,见下图。 Bootloader就是我们刷电子产品时所说的固件。它是用来引导程序写入的。 当我们在IDE点击上传后,nano就会重新启动,芯片最先运行Bootloader,看有没有...

好啦,“吧啦吧啦”的话不多说,直接上手一个传感器:光敏电阻(LDR)。 下图可以看到,随着亮度的增加,电阻阻值是变小的。 让我们想想最开始学习Arduino 时,用电位器控制LED的亮度?那个将电位器的阻值通过analogRead(pin)函数将电位器的模拟信号(分压值0-5V)读取并映射到0-1023数字之间,实际上,光敏电阻也是一样的...

The Icarus is a cost-effective cellular IoT board built around Nordic Semi's nRF9160 modem and combines LTE-M, NB-IoT, GPS, accelerometer, USB, LiPo charger, as well as an eSIM with free data out of the box and a nano SIM connector. Control, monitor, and keep track of any asset, ...
5V (on my 5V Nano at least). The voltage divider reduces the 5V to 3.3v and stops the world from being destroyed (or at least the RX pin on the HM-10). 5V Arduinos see 3.3v as HIGH so we can connect the HM-10 TX pin directly to the Arduino RX pin without destroying every...
