How to Test LED Lights with a Multimeter

After learning about the basic details of an LED, the next step for any aspiring robot or electronic circuit builder is to learn about how to test an LED, which is much the same as the method used to test any diode with a multimeter. For this, one requires a multimeter, and of course, the LED to be tested. After the setup is correctly followed, a forward voltage drop will be displayed. This information aids one in assessing the voltage requirement for the diode, which in turn indicates the battery power needed to power the robot or circuit.
