Provide answers for the following: a)      In Karnaugh Maps, what distinguishes cells that are adjacent and cells that are not? b)      For grouping of 1’s, each 1 must be included in at least one group. Is this statement correct (Yes/No)? Please explain your answer.

In step 2 you measured the voltage across each of the LEDs. This is their “forward voltage” that is referred to in the LED component page, which is the voltage required to light the LEDs. Notice that the combined forward voltage of D1 and D2 is greater than 3.3V, the LEDs will not light up at all. You should also have noticed that the forward voltage for one of the LEDS is lower than the forward voltage for the other LED. Some LEDS require less energy to light than others. Since D1 and D2 are in series, the same current will flow through each, but the different voltages across each LED reflect the different energy requirements. Finish each statement below, bears on this information and in the measurements you took in step 2 The measured forward voltage across D1 in this step is ________ The measured forward voltage across D2 in this step is ________
