I have done the set up for Blynk on the RPi B+ and if I use the LXTerminal and navigate to the folder and do the run command with my token entered I can activate and deactivate the pin I want. But now I want to send information back to my phone, using the LEDs, graphs and LCD widgets.
The problem I am having is knowing how to program it, I downloaded geany on my RPi (because you can write C and C++ programs on it) but I am new at that and I have tried running a blink the virtual pin LEDs, but it is made more for the Arduino so somethings are not being detected and when I google these things I get no downloads or any good information.
Does anyone know any simple tutorials I can follow, or videos. Or even if you can help me on this I would be grateful!
What I really basically want is a program that will output a GPIO signal when the button is pushed (as I said I can do that using the LXTerminal), this will open my door, I also have the plans so a reed switch will send a current back to the pi which when sensed the program will make the virtual LED widget light up, this tells me the door is open, and of course there is a few extra parts as well!
List of what I want to know:
- What program to use and how to install to Raspberry Pi B+
- What is the API for LED and sensing the button widget pushes or where can I read a list of APIs
- Anything else I will need! (because I am very new to this)
Thank you for reading this and I hope it helps others as well!
