Arduino Things

I just bought a Pimoroni RainbowHAT and am now waiting for it to arrive from the UK!

Here I found an excellent first getting acquainted with this platform: http://richardhayler.blogspot.nl/2016/12/getting-started-with-android-things-and.html

SSH and RPi Raspbian Jessie PIXEL 25 nov 2016

It seems the SSH default acess in Raspbian has been switched off in the latets (25 nov 2016) release.

But easy to get it going by creating an empty file in the root of the SD card with name ssh (jut that, no extension, no content required)

2016-11-25:
* SSH disabled by default; can be enabled by creating a file with name “ssh” in boot partition

So another little step to perform when preparing a SD card for headless first boot!

Oh, the system nags about password after enabling SSH:

sudo apt-get remove -y pprompt for the gui prompt

The CLI warning is raspberrypi-sys-mods, delete the file /etc/profile.d/sshpasswd.sh

Installing the Arduino 1.6.12 IDE on Raspberry Pi, with ESP8266 and RaspiDuino

Installing the Arduino 1.6.12 IDE on Raspberry Pi

1. Go to https://www.arduino.cc and download the Arduino IDE 1.6.12 for the ARM processor.
2. Open a terminal window.
3. Type cd ~/Downloads
4. Type tar -xvf arduino -1.6.12-*.tar.xz
5. Type sudo mv arduino-1.6.12 /opt
6. Type cd /opt/arduino-1.6.12/
7. Type chmod +x install.sh
8. Type ./install.sh

The new Arduino IDE will be in the drop down, along with your old Arduino IDE (probably 1.0.5 – which is installed when you type sudo apt-get arduino in a terminal window from the Raspberry). You will notice the difference immediately in the splash screen startup and the window pane header will read, “Arduino 1.6.12”.

ESP8622 with WiFi . If you are wanting to do this, navigate to File → Preferences and look near the bottom of the window that pops open for “Additional Boards Manager URL:”.

Type the following in the blank field:

http://arduino.esp8266.com/stable/packa … index.json

and click OK.

Now, go to Tools → Board “<your last chosen board>” and click on “Boards Manager” at the top of the list.

Type “ESP8266” in the Filter Your Search box at the top of the window.

Esp8266 by ESP8266 Community will show up. Highlight it and click Install in the lower right corner.
