下面是5V、3.3V的通路,其中3.3V给外部模块供电,5V给UNO Rev3 C区和A区供电。VIN 二极管D1后端的一段电路输出,也就是NCP1117的输入端。 插上插座PWRIN则一直有+5V主供电,当接上USBVCC(USB线)如果两边同时给+5V后端电路供电,理论上,PWRIN 大于6.6V,T1这个mosfet会关断,usb这个供电会被切断,如果<6.6V,两条...
一、 壁障小车的制作1、 制作壁障小车的准备工作硬件:Arduino UNO、L298N驱动模块、超声波模块、小车底盘、舵机模块、一块面包板、一些杜邦线。软件:Arduino UNO的程序下载软件下面来一张安装好的的图2、舵机模块的解析认识本次用的是简单实用的9克小舵机。它的扭力不是很大,但是对于咱们想用作扫描超声测距探头来...
The Arduino Nano Every contains the ATMega4809, a more powerful processor than the one in the Arduino UNO board. This allows you to compile a more advanced program, as it has 50% more program memory than the Arduino UNO ATmega328P. It also has 200% bigger RAM than UNO. If you are us...

with any orientation you need. We recommend first time Arduino users start with the Uno R3. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (5V), lack of connectors, and USB off ...
This is the new Arduino Uno R3. In addition to all the features of the previous board, the Uno now uses an ATmega16U2 instead of the 8U2 found on the Uno (or the FTDI found on previous generations). This allows for faster transfer rates and more memory.

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...
