Yeah sure. Here’s the schematic.

- Use diodes rated for your voltage. I use a maximum 12V, so this works fine.
- Use a different colour for odd leds ( LED1, LED3, LED5 ) and even leds ( LED2, LED4, LED6 ).
The working principle is very simple:
The diodes make sure the odd and even light up according to the current direction. For low voltages (below 5V) you can get away without diodes since LED are also diodes.
This setup is connected to a 3 phase driver output. It allows us to visualize the active phase and current direction.
