C/C++ on Intel Galielo/Edison: Part6 Light sensor

C/C++ on Intel Galielo/Edison

In this post, we will be using the upm library to interface the Grove Light sensor with the Galileo/Edison using upm on C++.
The light sensor is made up of primarily of LDR and opamp:

C/C++ on Intel Edison/Galileo – part5:Temperature sensor

In this blog post, we will explore the ways of interfacing a temperature sensor using both mraa and upm.

The Grove temperature sensor that we are going to use is a class of transducer know as the thermistor. It is called so because it's resistance (the 'istor') part is controlled by the thermal energy ('therm' part) applied on the sensor. We are going to use the Grove temperature sensor.

We have already learned from the previous blog post that with ADC, we can measure the change in the resistance of a device connected to the analog input of Edison/Galileo.

In this post, we will be using the upm library to interface the Grove Light sensor with the Galileo/Edison using python.
The light sensor is made up of primarily of LDR and opamp:

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.

C/C++ on Intel Edison/Galileo – part2: Buttons

In this post, we will be looking at using mraa library on C for interfacing with a button. For this example, the button will be used to turn on and off an LED connected to the Edison/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 Edison/Galileo itself.

"LDR" stands for light dependent resistor (in above schematic, it is marked as "LIGHT") as the name suggests, it is made up of a material that changes it resistance depending on the intensity of the ambient light.

Blockly on and for Edison/Galileo - work in progress

Just a quick post to give you guys a heads up on what I have been working on.

I've been working on bringing Blockly onto Edison/Galileo. The plan is to have blockly server being hosted by Edison from within the blockly interface, one should be able to upload and execute the generated Arduino sketches.

Blockly is visual programming tool using which you can whip out functional code with great ease. It consists of predefined blocks. Combining them you can create executable code targeting a number of platforms. I am basing this on the BlocklyDuino project.

If you are looking for something similar but better, have a look at wyliodrin.

In below video you can see Edison serving up the Blockly. Using the Blockly interface you can see me put together a simple LED (again connected to D5) blinking code.

Compiling Arduino sketchs on Galileo/Edison from command line

For some time I've been playing around the idea of compiling and executing Arduino sketches right from the Galileo and Edison. In this post I'll detail out the method that I used to accomplish this task and will also note down the investigation that I had to do in order to do this.

Cloud 9 IDE on Edison

One of the things I like about the BeagleBone(Black) is that it comes with Cloud 9 IDE off the shelf which means that you do not need to install any kind of software (other than a browser) on your host system to start developing something on the board.

In this post we are going to talk about bringing the cloud 9 IDE experience onto the Edison.

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.

Getting started with Edison

This post is going to be little quick start guide for the Intel Edison. Intel Edison is tiny compute module which packs lots of features in that package. It features a dual core Atom processor along with a Quark (for I/O) and also packs in bluetooth, wifi and eMMC.

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.
