INDEX

NOTE:
Remember about the input voltage limitations. Remember about the heat sink of the voltage regulators before touching the voltage regulator IC because it will be in the heated state normally .
Your hand will get burned(not big burn,some small) if we touch the heat sink of the voltage regulator. So first touch the heat sink gently and confirm it is not heated, then only remove the IC from the breadboard. If you are driving high power circuits and motors from the output of the voltage regulator screw an external heat sink to the voltage regulator. Size of the heat sink depends on the output power driving.
