Custom slider controls in Scratch

scratch screenshot 03

To acquire user input for the Scratch version of Grisbot’s computer interface, I’m using slider controls. In the above example, I’ve made a ‘slider icon’ in the form of a red ‘I.’ Position the mouse over the icon and hold the mouse down, and the icon moves with the mouse position along the scale. The icon position correlates to a servo timing value which will be saved in a variable for transmission to the robot.
