Product overview
The LED Buddy can help you to design any electronic circuit that includes one or more LEDs.
Hold any type of LED to the contact pads of the LED Buddy to start the process. It detects the
polarity of the LED, measures the forward voltage and auto-calculates the series resistors that you
need to use.The compact size and durable materials ensure that this useful tool is the best buddy
any maker can have. No more circuit troubles!
Specifications:
dimensions: 75 x 32 x 48 mm (W x L x H)
calculated voltage adjustable from: 0 - 30 V
calculated current adjustable from: 2 - 26 mA
current consumption: 40 mA (when testing a LED)
power supply: 9 to 12 VDC max. or 9 V battery (not incl.)
Schematic explanation:
The main purpose of the LED buddy is to aid the user in the calculation of the series resistor for
limiting the LED current.
