3.Supports simple circuit simulation
4.For students, teachers, creators
Profession
1.Brand new interactions and interfaces
2.Smooth support for design sizes of over 30,000 devices or 100,000 pads
3.More rigorous design constraints, more standardized processes
4.For enterprises, more professional users
STD ArduTest LED
Profile：An Arduino based LED Tester with LCD. Select the current and the destination voltage (your battery), connect the LED to the tester and get the needed value for a serial connected Resistor. You can also see the measured values for the LED (forward voltage and current). Based on the idea of https://jaycar.com.au
