    Raspberry Pi Garage Door Opener

    I had been wanting to make this project for months, and the wall switch for my garage door broke so that was my excuse to do this. I'm so excited to have a smart garage door opener. I made several tweaks to the code which can be seen on Github at https://github.com/JoshuaCarroll/Raspberry-Pi-Garage-Opener. Thanks for sharing your knowledge on this!

  • Detect Temperature and Humidity with Raspberry Pi and HTU21 / SHT21

    Thanks for writing this! I was able to use this to test my temperature and humidity sensor.I followed all of the steps, but when I ran the make command, I was getting the following error message:pi@raspberrypi:~/rpi-examples/HTU21D/c $ sudo makegcc -c -o HTU21D.o HTU21D.c -I.HTU21D.c:3:22: fatal error: wiringPi.h: No such file or directory#include "wiringPi.h"^compilation terminated.Makefile:8: recipe for target 'HTU21D.o' failedmake: *** [HTU21D.o] Error 1To get around this, you need to runsudo apt-get install git wiringPior simply include it in the command from Step 3 like this:sudo apt-get install git build-essential i2c-tools wiringPi

    I have followed all of the steps, but when I run the make command, I get the following error message:pi@raspberrypi:~/rpi-examples/HTU21D/c $ sudo makegcc -c -o HTU21D.o HTU21D.c -I.HTU21D.c:3:22: fatal error: wiringPi.h: No such file or directory #include "wiringPi.h" ^compilation terminated.Makefile:8: recipe for target 'HTU21D.o' failedmake: *** [HTU21D.o] Error 1Please advise.
