Features

  • Tap colour buttons to assign the colour to the resistor.
    • Tapping on 12 colour buttons will set the button colour to the resistor below. The position indicator shows where the next colour will be assigned. If you see the resistor shook, you are assigning invalid colour for the position. 

 

  • Drag colour buttons to any positions on the resistor to assign the colour.
    • The colour buttons are draggable. When you drop the button on a stripe on the resistor, the colour will be assigned to the stripe. If you see the resistor shook, you are assigning invalid colour for the position.

 

  • Swipe DOWN to switch between 4 bands and 5 bands
    • Swiping by 2 fingers switches the resistor between 4 bands (brown) and 4 bands (blue) resistor. The colour of the stripes will be reset to default (10 for 4 bands and 100 for 5 bands)

Apple Watch Glance

Apple Watch Glance Screen Glance for the Apple Watch shows current time with the resistor colour codes.
For example, Black-Black-Orange-White is 00:39 AM. Blue resistor means AM and Brown means PM.
