You can use a DHT11 to measure temperature and use a relay to switch on fans and ac if thats what you meant.
Also how do you plan to control the house temperature. You can't control temperature using sensors. Sensors just Sense
Is your HDD connected to Pi via USB?. If it is you can't boot unless you enable usb booting on it.
Did you properly flash Ubuntu to HDD ? Try setting the boot bit https://www.raspberrypi.org/documentati ... des/msd.md
Hello Lindiml, If you want to communicate between two RPis you can use Python sockets . Just connect the two Pis to same network (eg: Wi-Fi hotspot). Python sockets is easier to use. So try that. And for doing projects getting to know about pi is not necessary. Pi is like a mini computer with more c...
Hey Guys I figured how to control the robot via computer. I used python sockets to send messages between pc and pi. And for the GUI i used Kivy (GTK might be better) to get sensor values and to control it. To display the MJPEG camera stream in the GUI , I used OpenCV capture to do that. There's late...
This is a very basic question. :) First read whats written on the computer fans power requirement (most of the are 12v). Soldering isn't required for this. Just connect the positive wires of every fan and negative wires of the fan.(+ & - separately) and use any 12v DC adapter to power them. That's a...
It is possible according to stellarium source forge discussion and there are programs for that called Stellarium But it may be slow on the pi. On their website, one person got 18 fps. The new raspberry pi 3b maybe faster and have 1 GB ram, zero might be slower. I haven't used GPS with raspberry but ...
Hello TatarPro What drone are you making ? NVM :D . I have a similar project but its a rover. Python is easy but if you know c++ that will be better. You'll need wifi(router or connect pi to a wifi) to do this I am planning to use python sockets for controlling. And you could easily make a GUI in a ...
Thank you all for the replies :D :P . we was thinking of having plastic, paper, and metal. realy just the main litter in school and i think the idea with multiple flaps and a lazer to stop cheating is great. :D You can detect objects by reflection. Put a torch or led in it and LDR to see whether th...
Hi there Purple Dragon !! Why would you want to use Etcher on your pi. Ether is not necessary to flash in your pi., You could use the dd command. You should use Etcher in your PC to do that. And If you have already booted using sd card. You cant just remove it and add another sd card and flash it. A...
Dont do anything dangerous with your raspberry pi as it could get damaged even by connecting and led . You should try to stick with the Pi's Micro USB.
Why cant you use a buck to buck converter for that. You should provide voltage higher than 5v eg:12v. It will convert 12v into 5v. Buck to Buck converter to usb is available so you can use it as an normal power bank. Its much safer to power pi that way .
Anyway Thanks Guys I found sockets in python which allow me to do this. I'll try to stick with sharp develop python for the client side. and for the AI I will try to use OpenCV and any if else statements for navigation. I make it AI one day 8-) . I let you guys know when I have done the project :) ....
But is there a way to two way talk between raspberry and computer. I only found ssh but implementing client side is difficult. Any other ways of controlling the robot other than web browser ?
Yes Andyroo I'm after a wondering robot which wanders here and there in a building. I didn't find any good resources or libraries to start learning how to make this. I'm planning to use accelerometer and gyroscope for navigation and i can't buy gps (because they are not cheap and not accurate). Ther...
I'll look into into. But I'm not trying to control it using voice. I want to control it from another computer. Not with VNC, With a dedicated program using ssh. The AI is very confusing.
You should use an online speech to text convertor to get text https://tutorials-raspberrypi.com/build-raspberry-pi-voice-control-for-home-automation/ and convert text reply to speech using text to speech convertors (most of them works offline) I don't know to make AI but you can script the speech be...
I didnt mean to disappoint you but its hard to detect what garbage have been put.
If you use a camera to detect what waste have been put, it will be harder to recognize the garbage.
You'll have to use opencv to recognize garbage and train to recognize garbage
You can use ultrasonic eg: if a person passes near the ultrasonic the distance reading changes so you can say that a person passed.
and optionally you can use a 7 segment display to display the time, or even better a computer monitor.
Hello NSG650 I guess that the relay was clicking because when the raspberry pi boots its gpio pins are not programmed/ or dont know which state they were last, the gpios maybe high or low. You could have used arduino with raspberry to control the irrigation system :) What did you use to power the re...
Hello If you want to water measure water level you can use an ultrasonic sensor and for the alarm a motor driver. Motor driver is used for controlling heavy load items other than leds And you can use ssmtp to send email How to use Ultrasonic https://projects.raspberrypi.org/en/projects/physical-comp...
