Wireless USB adapter in raspbian

Hi
I was using my tenda USB WiFi adapter to connect my raspberry pi 2 to the internet. I was new to raspberry pi and was experimenting on it continuously. Unfortunately while trying to set a WiFi hotspot on my raspberry pi I was interrupted by some errors and tried to rollback the changes manually. Now the USB adapter is not detected by the raspberry pi GUI WiFi manager. I've checked the adapter on PC and its working good. When I use lsusb in pi I still see the adapter connected to my USB. Also the ifconfig lists the wlan0 details.
I am now unable to connect to any WiFi network either by command prompt and GUI. Please help me.
Thank you.

so "lsusb" lists your device, and not just the ports right? Can you "ping" anything inside or outside your local network? It may be that the wireless driver is missing or broken. You can check installed device drivers by typing "cat /proc/devices" in a terminal.

Raspberry Pi smart doorbell -- Help

Hi guys! , I saw on youtube and on vibell.org, a solution for a raspberry pi based smart doorbell.
Currently, i own the first raspberry pi (RASPBERRY P1 MODEL B), a usb 2.0 camera, a breadboard, some buttons and leds.
I wan't to do the project has shown on this video: https://www.youtube.com/watch?v=SRZ6QxxXRdI , the thing is that this project is made with the raspberry pi camera module (that i don't own), and i want to use a usb 2.0 camera instead, in this project he also uses a usb sound card that i don't understand why, i would want do replace that usb sound card with the soldered one on the raspberry pi
But i don't know how
I'm a beginner with the raspberry pi and programming.
Hope you can help me !
By the way the site is : vibell.org
Waiting for answer!

Collect data from sensors and show on the android app, is it possible?

Hello guys!
I have a raspberry PI 3 (model b) with all necessary accessories and different sensors such as (DHT11, BMP 180, MQ-2 etc.)
So far I have managed to install Raspbian OS and log-in to PI using Putty via Wi-Fi (as I don't have external screen)
1. Is it possible to connect many sensors let's say about 3 to 5 to a single breadboard connected with raspberry PI 3?
2. Once the sensors are added successfully is it possible to collect and send data to the android app? Let's say if I create a very simple looking android app and then I can see the temperature directly from the sensor on phone?
I know there are different IoT platforms that allow sharing data in the cloud, but I want to build everything from scratch.
I am a beginner on this, so I am still studying and reading but would appreciate if someone could give me some guidance where to start.
Regards

you can use and adruino and a bluetooth module to connect it to a raspberry pi and build an app to receive and display the data from the sensors. building one myself for a project.

U can do something like this with raspberry pi + arduino
https://github.com/Ayush1325/SmartHomeModel
Raspberry pi and arduino are connected via a simple serial usb cable that comes with arduino.
It uses PubNub as the server and arduino and Android phone are connected to internet.

why not just RDP or use JuiceSSH for viewing remotely

How to run multiple App on one Pi?

Very new to this whole raspberry pi thing.
Long story short, I recently bought a pi zero w and manage to install pi-hole and config my home network to go through it when I browse the net.
This got me very excited so I start looking into more pi projects.
The next thing I want to do is try to install Android TV box into the same raspberry pi. I was wondering if the zero w is powerful enough to run both pi hole and android at the same time or do I need to order another one?
If it is powerful enough, I am currently running Pi Hole off Raspbian, is it possible/how to run both at the same time?
I found a few guides on how to install android tv but cant get my head around running both at the same time.
Thanks:good:

carPC for raspberry pi 3 b+

I need help have some version ported to raspberry pi 3 b +? I can not find out if there is any project with Android? Or can someone make a version for raspberry pi 3 b +?

I am trying to do the same thing with "Raspberry 3 B";
Try "Emteria OS" it works the same with "Raspberry 3 B+", half a year it have problems with Bluetooth on the "3 B+", but maybe the fix the bugs.
