Try something like

NDSolve[{y''[t] == -y[t], y[0] == 1, y'[0] == 0}, y, {t, 0, 1},
 StartingStepSize -> 1/10,
 Method -> {"FixedStep", Method -> "ExplicitEuler"}]

For more details and to see what methods and other options may be
specified, see the tutorial

Advanced Numerical Differential Equation Solving in Mathematica

in the documentation. The above example is taken from there.
