Arduino lightsaber upgrade

上網找了一下,應該要用更小規格的LilyPad Arduino

規格如下,不過看了價格.....還是 Nano有優勢.

Microcontroller	ATmega168 or ATmega328V
Operating Voltage	2.7-5.5 V
Input Voltage	2.7-5.5 V
Digital I/O Pins	14
PWM Channels	6
Analog Input Channels	6
DC Current per I/O Pin	40 mA
Flash Memory	16 KB (of which 2 KB used by bootloader)
SRAM	1 KB
EEPROM	512 bytes
Clock Speed	8 MHz

上回的code把全部的digital pin都用掉了,剩下的pin為Analog,不用上就可惜了.
以下圖為Touch Switch的接法,經測試,不接5V以及PNP電晶體,也是可以有一樣的功能.

重新改寫Code,採用sub function的方式撰寫,方便有興趣的朋友進行修改.
追加一段閃爍控制,主要功能是用來強化LED 揮舞時出現閃爍的感受
追加Analog Touch SW的sub function.實際功能等想到再規畫吧!

效果要實際測試調整delay的速度.
Code展開如下.

#include "softwareserial.h"
#include "dfplayer_mini_mp3.h"

int LEDstatus = 0; //定義變量為LEDstatus
int Touchstatus = 0;
bool hum[4];
int sensorValue;
int prevValue;
const int LEDdelay = 20;  //定義延遲0.020秒進行一次LED升降50FPS
const int BreatheStep = 5;
const int PowerSW = 12;
const int WaveSW = 13;
const int LEDMartix[10] = {11, 10, 9, 8, 7, 6, 5, 4, 3, 2} ;  //設定LED Martix
const int PWMpin[10] = {1, 1, 1, 0, 0, 1, 1, 0, 1, 0}; // PWM: 3, 5, 6, 9, 10, 11. Provide 8-bit PWM output with the analogWrite() function.

int CheckTouch(int AnalogPin) {
  prevValue = sensorValue;
  sensorValue = analogRead(AnalogPin);
  if (sensorValue >= 1023 && sensorValue >= prevValue) {
    return 1;
  }
