BeagleBone Tutorial

For the next part of my series on PocketBeagle, I will show how to add WiFi connectivity to the board. This board doesn’t come with built-in WiFi like the Raspberry Pi Zero W. With a simple hack, I managed to add WiFi connectivity to it.

I am a fan of the BeagleBone Black. Thus when I heard that a small-body version of the BBB is now available, I purchased it immediately even if it costs twice as much as the other small-body SBC, the Raspberry Pi Zero. The PocketBeagle, as it’s called, also doesn’t have …

Last year, both Raspberry Pi and Beaglebone Black released mini versions of their popular microcomputers: the Raspberry Pi Zero and PocketBeagle. I happened to own both and had a chance to compare. Which small-size single board computer (SBC) is better? It’s Raspberry Pi Zero vs. PocketBeagle after the jump.

Using the Beaglebone Black’s PWM Bonescript also includes an analogWrite function which utilizes the 8 PWM pins of the Beaglebone Black. As you might already know, PWM allows us to control a servo motor. The analogWrite function accepts the pin name, duty cycle, frequency, and callback function as parameters. The …

Using the Beaglebone Black ADC One of the advantages of the Beaglebone Black over the Raspberry Pi is the presence of an analog-to-digital converter. There are 7 analog inputs, all at P9: To process analog signals, we’ll be using the analogRead() function. Note that the analog pins can only read …

Using a Button As you’ve noticed, the functions in bonescript are similar to Arduino’s. If we are to use an input device such as a button, switch, etc, we only need to change the direction using pinMode: var b = require('bonescript'); b.pinMode("P9_12", b.INPUT);   The script below reads the state …

Blinking On-board LEDs The simplest bonescript we can create right now is to blink one of the four user LEDs. The user LEDs are those four blue LEDs just above the miniUSB port: On Cloud9 IDE (192.168.7.2:3000), open a new file (click the + tab) and then paste the following …

When you browse a website, you are requesting the contents of the web page from or using the calculating capabilities of a server somewhere. That server is almost always a Linux machine and server-side scripts like PHP, Python, and Node.Js are used to “talk” to these servers.

Ah, the Beaglebone Black. This credit card-sized computer was meant to be the Raspberry Pi’s competitor and sure lives up to it. Its users are way less than RPi’s, which is understandable, given the Pi’s appeal to beginners and the like. But if you would ask me what to choose …

We covered the Beaglebone Black I2C basics in our last tutorial. This time, we’ll try to communicate with a device through the I2C protocol. This device, the MPU6050, is a gyroscope + accelerometer integrated circuit that is very popular among makers and enthusiasts.
