How to make a Beaglebne and Arduino communicate. by chwei
Say you’ve got this nice Ardunio project that provides serial data, but it needs a FTDI and you don’t want to tie up your BeagleBone’s (or BB) USB port or use a hub. Well, it’s not as hard as you think, and you don’t need a FTDI!
The BB has 4 TTL serial ports available, and this how-to will show you how to use one to talk to an Arduino. I’m going to show this by using a minimal Arduino on a breadboard, but you can do this with a normal Arduino as well, just use an external power adapter and don’t plug in the USB. The “gotcha” to this is that the BB’s ports run at 3.3VDC and the Arduino runs at 5VDC. We’ll solve that using a logic level shifter.
Things you’ll need:
– Breadboard and some jumper wires
– a BeagleBone (any revision including black should work the same)
– an Ardunio
– a Logic level shifter that supports 5v-3.3v and bi-directional on the TX line.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
