Something I threw together to demo the accelerometer and LED.  Hold down switch_1 to calibrate, LEDs off (flickering a bit) indicate you're back where you calibrated.

Public Domain, do what you will with it.

Code: [Select]
#include <Esplora.h>

const uint16_t SAMPLES=64;

int calx=0, caly=0, calz=0;
long sums[3] = {0};
uint8_t index = 0;

void setup() {
Serial.begin(115200);
}

void loop() {
int rx, ry, rz;

calx=rx, caly=ry, calz=rz;
} else {
rx -= calx, ry -= caly, rz -= calz;
for (uint8_t i=0; i < 3; ++i) {
}
sums[0] += rx, sums[1] += ry, sums[2] += rz;
index = (index + 1) % 64;
rx = sums[0]/64, ry = sums[1]/64, rz = sums[2]/64;

Esplora.writeRGB(abs(rx), abs(ry), abs(rz));
}
}

Oops, made a variable and forgot to use it!
Code: [Select]
#include <Esplora.h>

const uint16_t SAMPLES=64;

int calx=0, caly=0, calz=0;
long sums[3] = {0};
uint8_t index = 0;

void setup() {
Serial.begin(115200);
}

void loop() {
int rx, ry, rz;

calx=rx, caly=ry, calz=rz;
} else {
rx -= calx, ry -= caly, rz -= calz;
for (uint8_t i=0; i < 3; ++i) {
}
sums[0] += rx, sums[1] += ry, sums[2] += rz;
index = (index + 1) % SAMPLES;
rx = sums[0]/SAMPLES, ry = sums[1]/SAMPLES, rz = sums[2]/SAMPLES;

Esplora.writeRGB(abs(rx), abs(ry), abs(rz));
}
}

Awesome!!  This could also be ported to use the LCD display to great effect.  Good work!
