It reports the state of a digital pin - including the Arduino's feature that an unconnected pin has an indeterminate state (could be 1, could be 0) A long tap on these will stop a running program I've added reset buttons to the microcontrollers - like a real Arduino.I've improved the graphics for components (especially transistors and diodes), also I've improved the colours so wires and things show their on/off states better.You can still edit the circuit definition directly if that's what you're into And as if that wasn't enough, you can now pick new components from a sidebar list and drop them on the breadboard. A big change is that you can move components just by dragging their connectors.I've also improved the transistors sample (delete that sample then reload all samples to get the new version).I've added a sample circuit (named motor) that demonstrates using a transistor to control a motor.I've got ideas for other components like this in the future There is a new workboard area in the middle of the screen, where you can place motors and batteries.Now you can build circuits that really demonstrate how transistors work

I've added a few new components: a battery and a motor.This is only a minor release, but there are some huge changes.
