Smoother grid in a plot

I'm trying to plot a smoother grid in the background of this grid that's already plotted. This is what I've done so far. The grid follows my major ticks. I'd like this smoother grid to follow the minor ticks. Is this possible?

My code until now: 

fig, ax = plt.subplots(figsize = (20,10))

ax.set_xticks(np.arange(0,round(max(datax)+1)))
ax.set_yticks(np.arange(0,round(max(datay)+1),step = 0.1))
ax.minorticks_on()
ax.grid(True)
plt.xlabel("Tensão (V)", fontsize = 14)
plt.ylabel("Corrente (mA)", fontsize = 14)
plt.title("Experimento 2", fontsize = 20)
ax.errorbar(datax,datay,xerr = sigmax, yerr = sigmay, fmt = ',')
ax.set(xlim= -1, ylim = 0)

P.S.: would you guys organize this code differently? I think it's a complete mess.

i want my grids to look like this this is how they are now

What you want is the linestyle keyword argument for grid, along with the linewidth keyword argument.

Here's how you can use dotted lines for your grid, with thinner lines for the minor ticks:

ax.grid(True, which='major', linestyle=':', linewidth=1, color="black")
ax.grid(True, which='minor', linestyle=':', linewidth=0.5, color="black")

Here's the output (I used faked data since you did not provide a MWE):

enter image description here

You can fiddle with the linewidth parameter to have the lines appear thinner, or on the color to make them fainter. You can also try other linestyles out, like dashed (linestyle='--').
