Prepare for lift off
The atracive feature of the board is that it could be programmed via the Raspberry Pi's UART
pins and hence eliminates the need for a USB port. The board could be either powered via
the Raspberry Pi or through the Micro B USB port using a wall wart transformer. The product's
webpage, http://wyolum.com/projects/alamode/alamode-getting-started/ ,
offers a single step process to start using the board.
The Raspberry Pi AlaMode mode is just one example of the stackable
Arduino hardware. There are probably other similar stackable Arduino
hardware available in the market. For example, https://www.
kickstarter.com/projects/raspitv/raspio-duino-
affordable-arduino-programming-on-ras .
Engage thrusters
1.
Once the archive is downloaded from their web page, we extract the contents:
tar -xvzf alamode-setup.tar.gz
2. Once the files are extracted, the setup is as follows:
sudo ./setup
3. Ater the installaion is complete, the Raspberry Pi a la mode's serial port is
enumerated as /dev/tyS0 .
Objective complete - mini debriefing
Ater the installaion is complete, we should have the Raspberry Pi AlaMode mode
enumerated and be ready to start programming the hardware add-on board.
The Weasley weather clock
We will build a Weasley weather clock in this project using an Arduino microcontroller board
and the Raspberry Pi. The Weasley Weather clock is inspired by the Weasley clock seen in
the Harry Poter series of movies. A Weasley clock is used to idenify the current locaion of
a family member of the Weasleys (for example, work, school, and so on) and also the safety
of the family member. Mrs. Molly Weasley (the matriarch of the Weasleys) used the Weasley
clock to keep tabs on her family and this clock has had its variants over the years. This project
happens to be one of them!
