Subsection float barriers with figures/Tables

I adjusted the markup in a few places to arrive at

Basically you should not worry about the float placement until the text is done and then at the end you could add clearpage if needed before a section heading to flush any floats that are floating too far.

item Place the LED in series with R, 
$V_{DD} = 5mathrm{V}$ while varying $V_{GS}$ from 0 V to 5 V. Record when the LED starts turning on; this will determine when the transistor is in the on state for overcoming Gate Source voltage required. 
item Remove the LED and increase $V_{GS}$ observed by 1 V. Step up $V_{DD}$ from 0V : 8V in 1V increments. Measure $I_{DS}$ and $V_{DS}$ for each step value and calculate $R_{DS}$ from these values and Power found by P = power dissipated from transistor ($P_{R_{DS}}$) + drain connected resistor ($P_R$)
