C/C++ on Intel Edison/Galileo – part4:ADC

ADC is a peripheral that lets you input an analog signal and outputs the digital representation of the input analog signal.
The world in which we live in is surrounded by the analog signals. The temperature, sound that hear, the light that we see are all analog signals. If you want to interact or measure these signal in a digital system like Galileo/Edison, you’ll have to use ADC a.k.a Analog to Digital Converter.

C/C++ on Intel Edison/Galileo – part3: PWM

In this blog post, we are going to look into the ways of mraa functions used for controlling the PWM module available on the Galileo/Edison. In this tutorial, we will using PWM to control the intensity with which the LED glows, connected to port D5. The LED starts of with lowest intensity and then gradually increase the intensity until it reaches the maximum intensity and then decreases the intensity gradually until the LED is at the lowest intensity and the cycle continues.

TwitterPlotBot on Galileo/Edison

As you might have guessed from the title of this post, we are going to build yet another Twitter bot on Galileo. So what does it do differently then? It tweets the picture of the plot of the temperature(or any other parameter that you wish to see) right to your Twitter feed.

Python on Intel Galileo/Edison – Part 5:Temperature sensor with mraa and upm

The temperature sensor that we are gong to use for this post is from Grove. This sensor outputs the voltage that represents the temperature hence we will need the ADC module on the Intel Galileo/Edison to interface with this peripheral.

Python on Intel Galileo/Edison – Part 3: PWM

In this blog post, we are going to look into the process of using mraa methods for controlling the PWM module available on the Galileo/Edison.

What is PWM?
 PWM stands for pulse width modulation. As the name suggests, there is a “pulse” and with “width”, we mess(“modulation”). The idea here is to change the width of the pulse, resulting in another pulse that meets our needs.

Python on Intel Galileo/Edison – Part 2: Buttons

In this post, we will be writing a Python script to read button inputs.
As in previous post, mraa library is used for handling the GPIO. For this example, the button will be used to turn on and off an LED connected to the Galileo. This example is going to be very similar to the previous one. The only difference being that the state of the LED is controlled by a button instead of the program running on Galileo itself.
