主板:arduino UNO (手头有主板,就不想nano主板了,要不尺寸可以做小的)电源:7.4V 18650电池无线模块:蓝牙2.0控制端:手机APP电机驱动:DRV8833(很小的,差不多拇指那么大)电机:N20 + 支架 + 联轴器3mm的轮子:用72mm宽轮子底盘:亚克力(3层)其他配件:铜柱、开关、杜邦线、短排母、螺丝、DC电源头等等做的时候还是...
The Nano has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. Analog pins 6 and 7 cannot be us...
All it takes is an Arduino Nano R3 or comparable microcontroller, an RGB LED ring with 12 LEDs, a 16×2 LCD, a buzzer, and a momentary push button switch. Interestingly, there aren’t successive levels with increasing speed, but each round begins with a randomized speed value. Of course...
· shiftOut(dataPin, clockPin, bitOrder, value)SPI外部IO扩展函数,通常使用带SPI接口的74HC595做8个IO扩展,dataPin为数据口,clockPin为时钟口,bitOrder为数据传输方向(MSBFIRST高位在前,LSBFIRST低位在前),value表示所要传送的数据...

#define 是一个很有用的 C 语法,它允许程序员在程序编译之前给常量命名。在 Arduino 中,定义的常量不会占用芯片上的任何程序内存空间。在编译时编译器会用事先定义的值来 取代这些常量。 然而这样做会产生一些副作用,例如,一个已被定义的常量名已经包含在了 ...

This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. This RTC is the most precise you can get in a small, low power package. Using our Feather ...
