The Ohmmeter 2.0 displays resistor band colors

The Ohmmeter 2.0 displays resistor band colors

from arduino.cc

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 — developed by Miguel Alejandro Ramírez Anaya and José Miguel Galeas Merchán from the University of Málaga in Spain.



Their Arduino Mega-powered device has three modes. First, it enables you to enter resistor value with a keypad and then displays the corresponding resistor colors on a large 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.



You can find more details on the students’ Ohmmeter 2.0 here and see it in action below.

 

If you're interested in making your own version, PMD Way has you covered with a huge range of parts including Arduino Uno compatible boards, a wide range of illuminated buttons, and more.
