2. I work at
3. What is
4. Why hardware?
5. PHP • Ugly language • Hated by hackers • Most tutorials in Python, Ruby. • Arduino mainly in C
6. PHP • But we love PHP!
7. PHP • But we love PHP! • Because it’s like the mother of language, C! (excuse)
8. PHP Anyway, we’re most proficient with it!
9. Hardware is not scary
10. Hardware is not scary is just I/O
11. Hardware is not scary is just I/O just like file-handling /sys/class/gpio
12. Pins
13. GPIO is all we care (for noobs at least)
14. GPIO is all we care (for noobs at least) + some basic electronics
15. GPIO WiringPi https://github.com/WiringPi/WiringPi C-based very simple
16. WiringPi gpio mode 1 out gpio write 1 1 gpio write 1 0
17. WiringPi-PHP PHP wrapper for WiringPi https://github.com/WiringPi/WiringPi-PHP Requires compilation (is it ready?)
18. PHP-GPIO PHP wrapper for /sys/class/gpio https://github.com/pickley/PHP-GPIO Simple to setup
19. PHP RasPi GPIO Libs • WiringPi-PHP • Userland • Requires compilation • PHP-GPIO • Easy to set up • root :(
20. Demo time! https://github.com/uzyn/raspi-gpio-demo.php
21. PHP web language tons of frameworks + libraries scripts easy!
22. PHP + Hardware world domination
