    <p>I am trying to make a simple Arduino game that keeps track of the number of times a button has been pressed. There are two buttons, one for each user, and whoever is closest to the random number that the Arduino picks, wins. "winning" being a light comes on next to the winers button. However I am stuck in what seems to be a rut—before I go further, I will divulge that I am just barely two weeks old into the whole arduino/C++ environment so my knowledge is pretty low. </p> <p>Basically what I want to happen is that the game lasts a certain amount of time, lets say 5 seconds, then after the five seconds, all the button pushes are tallied and compared and a winner is picked. Then the game resets itself and we can play again. Where I am getting stuck at is in the timing function. I originally was subtracting a <code>gameClock</code> variable from the <code>millis()</code> function however I have read that it is bad practice to reset the <code>millis()</code> function. Perhaps my code will give you a better understanding of what I am trying to accomplish. </p> <pre><code>#include &lt;Bounce.h&gt; //Using Arduino UNO #define RBUTTON 2 #define RRLED 3 #define RGLED 4 #define MBLED 5 #define LGLED 6 #define RLLED 7 #define LBUTTON 8 Bounce BounceR = Bounce(RBUTTON, 5); Bounce BounceL = Bounce(LBUTTON, 5); int lastStateR = 0; int lastStateL = 0; int switchLCount = 0; int switchRCount = 0; long gameClock = 5000; void setup() { //LED from left to right pinMode(RBUTTON, INPUT); pinMode(RRLED, OUTPUT); //Red pinMode(RGLED, OUTPUT); //Green pinMode(MBLED, OUTPUT); //Blue pinMode(LGLED, OUTPUT); //Green pinMode(RLLED, OUTPUT); //Red pinMode(LBUTTON, INPUT); Serial.begin(9600); } void loop() { BounceR.update(); BounceL.update(); int total = switchRCount + switchLCount; int valueR = BounceR.read(); int valueL = BounceL.read(); if (valueL != lastStateL) { if (valueL == HIGH) { switchLCount++; Serial.print("Left button:"); Serial.println(switchLCount); Serial.print("Total: "); Serial.println(total); } } lastStateL = valueL; if (valueR != lastStateR) { if (valueR == HIGH) { switchRCount++; Serial.print("Right button: "); Serial.println(switchRCount); Serial.print("Total: "); Serial.println(total); } } lastStateR = valueR; } </code></pre>

    2. COIt's helpful to ask you question in the following format. "I want to do `X`. I tried `Y`, but when I ran it I saw `Z`. What should I do differently to see `X`?"

    3. COWow, an Arduino question that isn't about using Serial correctly. Still the basic loop problem, you only read the button state when you enter the loop. And then loop again by yourself without ever updating the state. So you can never see the button's being pressed.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
