Give this a try, if you still get the same issues, then the problem is with your touch sensor.When using the Serial monitor, you can save SRAM (Arduino has a limited amount) by putting your unchanging strings into the flash memory with the F() macro. Look for it in the code to see what i'm talking about.
#include <Adafruit_NeoPixel.h> //ledstrip lib
#include <CapacitiveSensor.h> //capacitive lib
#define PIN 6 // datapin for led strip
#define NUM_LEDS 45 //number of leds per strip
// initing led strip
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUM_LEDS, PIN, NEO_GRB + NEO_KHZ800);
//CapacitiveSensor tapper = CapacitiveSensor(4, 2); // capacitive sending ans sensing pin
int buttonPushCounter = 0, lastCount = -1 ; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous button state
unsigned long lastTap, OldTime = 0;
unsigned int Rain = 0, CW = 0;
byte P = strip.numPixels();
void setup() {
strip.begin();
strip.show(); // Initialize all pixels to 'off'
lastTap = millis(); //set millis
Serial.begin(9600);
}
void loop()
{
//read the capsensor: <1000=0, >1000=1 (>1000 is touch)
buttonState = !!(tapper.capacitiveSensor(30) > 8000); //<<------------------ is this correct???
// compare the buttonState to its previous state
if (buttonState != lastButtonState)
{
// if the state has changed, increment the counter
if (buttonState == LOW) {
// if the current state is HIGH then the button
// wend from off to on:
//long total = tapper.capacitiveSensor(30);
buttonPushCounter++; //actually increase counter
if (buttonPushCounter > 7)
{
buttonPushCounter = 1;
} // if the counter 6, then the counter will be reset to
Serial.println(F("on"));
Serial.print(F("number of button pushes: "));
Serial.println(buttonPushCounter); //serial print counter
//Serial.println(total);
}
else
{
// if the current state is LOW then the button
// wend from on to off:
Serial.println(F("off"));
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
}
if (buttonPushCounter != lastCount)
{
lastCount = buttonPushCounter;
Rain = 0; // reset the Rain variable in the rainbow function
CW = 0; // reset the CW variable in the colorWipe function

}

uint32_t Wheel(byte WheelPos)

}
else if (WheelPos < 170)
{

}
still the same happens...
maybe there is a work around. what about an extra "else" if the lamp is touched longer than 2 second to go in off state and return to the cases when touched again?
