The Ohmmeter 2.0 with the graphic display of the colors of the resistors

Bands on through-hole resistors conveniently indicate their value at a glance. On the other hand, you have to actually know the code to interpret this meaning. Alternatively, you could use the Ohmmeter 2.0.

The Ohmmeter 2.0, based on Arduino Mega, has three modes. First, it enables you to enter resistor value with a keypad and then displays the corresponding resistor colors on a large 3D printed resistor model via RGB LEDs inside. You can also input the color values directly using the keypad along with a small OLED screen. Last but not least, the Ohmmeter 2.0 can even measure a component’s resistance through a pair of terminals, replicating color values on the 3D model.
