Arduino Based LED Tester
Difficulty
Test & Tools
Summary
The display shows target current, LED forward voltage, actual test current on the first line and target supply voltage, suggested resistance and suggested Jaycar part number from the ½W range. If the resistor would dissipate more than half a watt, a P flashes on the top line to let you know you might need to choose a more powerful resistor.
