As of writing the latest Arduino IDE is 1.8.5. I prefer to download the non-install version (160 MB download). Just unzip on your preferred location on your drive, run the arduino.exe and wait for the Arduino IDE to initialize.
We have recently purchased an Adafruit Circuit Playground. I was really excited to finally able to hold it as it is a small board packing with a lot of features. Some of the features I have not used yet.
Here are the list of features of the Adafruit Circuit Playground.
Board Dimension: 50.6mm (2.0 inches) in diameter
Weight: 8.5 grams
ATmega32u4 Processor (3.3V, 8MHz)
MicroUSB for programming and debugging with Arduino IDE and power
USB port can act like serial port, keyboard, mouse, joystick or MIDI
2 pin JST port for Power (3-6V)
10 mini NeoPixels (each can display any color)
1 Motion Sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)
I had a hard time imagining how the microSD Card Breakout Board would fit physically into my project so I decided to create this post just in case you want to see close up photos of the breakout board.
I recently bought an Official Arduino Uno for me to do some prototyping projects.
So far I have done a lot of projects with my Arduino Uno and decided that it would be helpful if there are up close and personal photos of the Arduino Uno Revision 3 that is why I am creating this post.
I just bought the official casing of Raspberry Pi and I am very happy with it.
I always bringing my Raspberry Pi 3 inside its box for extra protection from being crushed inside my bag. Then I realized that sometimes I would like to use my Raspberry Pi inside coffee shops or in public places where I can work.
Having a bare Raspberry Pi board would make people doubt what you are doing since you are have an electronic board with you. Embarrassing if people would glance at you thinking that you are doing something bad. Seriously bad if a guard or police would approach you. These are the reason why I bought my case.

This is a tutorial on how to change the hostname of your Raspberry Pi.
If you usually do an IP Address scan whenever you connect your Raspberry Pi to a new WiFi network to find it then you should change the hostname of your Raspberry Pi. This is for you not to get confused when there are two Raspberry Pi’s connected to the network. At least you an select the right Raspberry Pi.
Just so you know the default hostname of the Raspberry Pi is raspberrypi.
Here is a tutorial on how you can setup Raspberry Pi without a mouse or a keyboard.
Most of us today only have laptops. We do not own a monitor nor a keyboard. But that should not stop you from trying Raspberry Pi. You can actually setup and use a Raspberry Pi without the monitor or a keyboard.
Note: I also find it annoying to setup a lot of wires just for the monitor and keyboard.
Here are the things you need to setup and use the Raspberry Pi without a screen or keyboard.
microSD Card (minimum of 8GB)
Power cable (standard USB cable for charging Android phone with charger)
For this tutorial I’ll be using Raspberry Pi 3 and my computer is running on Windows 10. My SD Card size is 8GB. Maybe I’ll create a tutorial when I am using my Ubuntu (Linux).
Below are the steps to setting up your Raspberry Pi without a screen or keyboard.
This is a tutorial on how to implement Pulse Width Modulated (PWM) in Raspberry Pi 2 and 3 using Python.
Since the Raspberry Pi 3 uses the BCM2837 and currently I could not find the specification sheet of BCM2837. I shall assume that the GPIO for the BCM2837 and the BCM2835 (Pi 2) are the same since the Pi 2 and Pi 3 Model B looks the same. I will use the Specification Sheet of the BCM2835 for reference.
I’ll check slowly check if there’s a difference among the two in terms of GPIO.
