If you want to do serial debugging for your PIC, ESP8266, Bluetooth module and a TTL-to-USB converter (pictured below) is nowhere in sight, you can simply use an Arduino USB serial converter! The Arduino UNO has its own FTDI chip whose function is to convert TTL signal levels to USB. …

I don't have a monitor for my Raspberry Pi so I use SSH to access and control it. I can do everything I need with SSH but sometimes I just grow tired of looking at the terminal and just want to point and click my mouse in using my board. …

One of the most important things your microcontroller can do is read analog voltages. It is important particularly in interfacing with sensors where most throw varying voltage levels that represent varying physical quantities (temperature, pressure, etc.). Microcontrollers, including the Beaglebone Black, have analog to digital converters to do this. Here …

When working on projects, there'll be lots of times when your microcontroller needs serial communication to talk to other devices or other micros. The most common example of this is adding IoT capabilities to your Arduino board or PIC using ESP8266 or GSM module. A number of sensors and LCD …

Now we'll use the Beaglebone Black PWM to control a servo motor. PWM, which is short for pulse width modulation, is widely used for controlling motors (dc and servomotors). PWM is also used in controlling power delivered to a load or device without using "power-eating" rheostat.

In this post, I flashed a LED connected to one of the Beaglebone Black's GPIO pins. Here I will flash the user or on-board LEDs on the device using the same method we did on the external LED.

The first thing I did when I had my Beaglebone Black (BBB) was toy with it using C++. The "hello world" of embedded programming is LED blinking so that's what I did. Note that the BBB has user-accessible on-board LEDs and controlling them is very similar to the method outlined here. …
