The push button in the parts list is what I have which is a simple single pole switch which only has an on-off contact. Even though it has 4 terminals. However the schematic shows 3 wires connected to the push button which does not correspond to the use of a single switch. Not only that the schematic also shows the push button being connected to the negative supply. In fact a close look at the connections shows two connections to the push button go to the same connection because the lower row of contacts are all connected together????? Black and Red both go to ground???

how do i read the value of analog 0 and then once the button is pushed it rolls the dice and i have A0 as a input. randomSeed(analogRead(1)); pinMode(analogRead (0) INPUT); //define shock sensor as a output port val = digitalRead(Shock); //read the value of the digital interface 3 assigned to val if (val == LOW) //when the shock sensor have signal do the following {

hey for some reason when i have the Arduino running it won't stop rolling the dice. it keeps re-rolling and only shows what it rolled for a brief second. i don't know what it is. can someone help me?
