Accelerometer music

Using the Arcbotics Sparki lesson to learn about the accelerometer, and I made my own version:


#include // include the sparki library
void setup()
{
}
void loop() {
sparki.clearLCD();
float x = sparki.accelX();
float y = sparki.accelY();
float z = sparki.accelZ();
sparki.print("Accel X: ");
sparki.println(x);
sparki.print("Accel Y: ");
sparki.println(y);
sparki.print("Accel Z: ");
sparki.println(z);
sparki.updateLCD();
if (y>=5)
{
sparki.beep(540,100);
delay(500);
}
if ((y<5)&&(y>=0))
{
sparki.beep(440,100);
delay(500);
}
if((y<0)&&(y>=-3))
{
sparki.beep(340,100);
delay(500);
}
if (y<-3)
{
sparki.beep(240,100);
delay(500);
}
}

Sparki accelerometer shake game

So one of the things I haven’t really explored with Sparki is the accelerometer. But as I recently got my hands on a Sphero Mini, I’ve been enjoying learning about this sensor.

So the accelerometer works on a 3 axis sensor. X, Y and Z.  X measures the left/right acceleration, Y measures the forward/backward acceleration, and Z measures the up/down acceleration.

Here is a little game I made using the data from the X sensor:

 sparki.clearLCD();
 sparki.drawString(10,1,"Hello human");
 sparki.drawString(10,3,"shake me when you see the");
 sparki.drawString(10,5,"GREEN LIGHT");
 sparki.updateLCD();
 delay(5000);
 int score=0;
 int counter1=0;
 while (counter1<10)
 {
 randomSeed(analogRead(1));
 int response1 = random(1,4);
 int counter=0;
 while(counter<response1)
 {
 sparki.RGB(100,0,0); // Make the LED maximum Red
 delay(1000);
 sparki.RGB(0,0,100); // Make the LED maximum Blue
 delay(1000);
 counter=counter+1;
 }
 sparki.RGB(0,100,0); // Make the LED maximum Green
 delay(1000);
 if(sparki.accelX() <0)
 {
 score=score+1;
 sparki.clearLCD();
sparki.print(score);
sparki.updateLCD();
delay(1000);
 }
 counter1=counter1+1;
 }
 sparki.RGB(RGB_OFF); 
 sparki.clearLCD();
 sparki.drawString(10,1,"Well done!");
 sparki.drawString(10,3,"You scored");
 sparki.updateLCD();
 delay(1000);
 sparki.clearLCD();
sparki.print(score);
sparki.updateLCD();
delay(1000);
 
delay(10000);
}

Here is a link to a video of the code in action: https://www.youtube.com/watch?v=a2HxYJC1TaQ

Free roam or boomerang

In this code, you can use the light sensors to tell Sparki what you want him to do. He can either, free roam in your room or a given area, avoiding obstacles, or use the boomerang routine, where he will explore the zone and return to the “home” area.

Handy to have a robot wandering around. Might attach a cloth so he can buff the floor as he goes 🙂

 #include <Sparki.h> // include the sparki library

Much improved rock, paper, scissors

Follow the instructions on the LCD screen. Use a torch to make your choice between rock, paper and scissors. This could easily be replicated with any LCD screen and 3 light sensors.

In this version, Sparki will also keep score. Although this will be displayed in the very top left hand corner instead of the middle of the screen as you would expect. This is because I haven’t yet learnt how to convert a variable of an integer value into a string to be displayed using the drawString(co-ordinates) command.

Here is the code:

Simon Says (LCD screen, 2 light sensors and a Ultra-sonic sensor)

Rock, Paper, Scissors

Inspired by Google Home and it’s ability to play rock, paper, scissors, I decided I’d quite like to play this with Sparki 🙂 after all, he is my favourite robot buddy! So here is the code for 5 rounds of rock, paper, scissors before a break, then he’ll ask you if you’d like to play again. Unfortunately, I haven’t wrapped my head around keeping score, I keep doing something wrong with my variables and they wont update with each round. So I just left it without scorekeeping for now.

#include <Sparki.h> // include the sparki library

  sparki.servo(60);
