Multiple buttons on a single motor

[Alan Anderson]

I was right, what you want is easy.

The triangular "Select" functions might be unfamiliar. The help describes them this way:

Returns the value wired to the t input or f input, depending on the value of s. If s is TRUE, this function returns the value wired to t. If s is FALSE, this function returns the value wired to f.

So when neither button is pressed, the motor is set to 0. When the forward button is pressed, the motor is set to 1 (full speed forward -- change the constant if you want some other speed). When only the reverse button is pressed, the motor is set to -1 (full speed reverse -- change it if you want).
