Your email address will not be published. I don't have the answer for you (...yet! Concerning the resistors, they should be 270Ω but since I don't have this precise value, I'm using 560Ω resistors (LEDs are just less bright). Disclaimer & Privacy Policy | About us | Contact. If you don't, check the index.php file, try re-installing PHP or try to understand the error displayed instead of the page (Google it if necessary). You just need to download it from GIT then to build it using the ./build command. Here we control an LED, connected to Raspberry Pi by using Apache web … 8. Web interface for Raspberry’s sensors (GPIO) In this example, we’ll use a Raspberry Pi and a DHT22 temperature and humidity sensor to print values on a web interface. Before we discuss http.server, let’s assumed that we have a little python script simple_gpio.pythat read Raspberry Pi’s GPU temperature from the Raspberry Pi, and it also control an LED connected to the Raspberry Pi. To turn it off, simply use the "gpio write 0 0" command. Let's make the interface! Now we will interface XBee module with Raspberry Pi which will act as a receiver and make it communicate wirelessly with another XBee module (XBee explorer board) which is serially connected with the laptop. You first need to set the pin as an output. Récupérer l’adresse IP du Raspberry Pi. The biggest surprise was near the end... learning english was not your native language. Finally the Wiring Pi library is containing a lot of other commands/functions but I'm not gonna cover them in this instructable since there are not useful here.
