Have you read the data sheet for it, the link is in one of the answered questions on banggood . “ MPU-60X0 collects gyroscope and accelerometer data while synchronizing data sampling at a user defined rate.” It uses I2C or SPI interface to the raspberry pi. yes I have been read but I didn't underst...

Since, from the nature of the questions, I assume this is for a class, your instructor should be the one to tell you what is intended to be between the routers, or else you should have taken a networking course before this one.

I found that Pi act like client that send data to PC running MS SQL server via TCP/IP My understanding that if two devices are communicating they must follow the some rule of logic called as protocols ADC to PI via I2C Pi to Router via ?

Hi Program read the data from sensor via ADC and Pi send it to database. There is one I2C protocols that communicate between PI and ADC. Pi sending data to another PC via wifi router with internet connection. I don't understand which type of protocol being used in program when PI talk to other devic...

Hi there

I want keep the record of temperature. I have DHT22 sensor is connected to Raspberry Pi3 Raspberry Pi should push data to cloud to an IoT service, Fansoluation.com and to a mobile App (Fan)

I have done some research work and found it can be done via MQTT protocol. would it work ?

Fan174

The 5V output is only 1.5A which may not be enough depending on what else is connected to the RPi. Thanks to all of you load 24V DC Fan http://shop.rabtron.co.za/catalog/80x80x25-p-137.html I don't want to damage raspberry Pi and other devices as shown in the image, Is it a safe connection?

Hello everyone

I would like to get IP address of raspberry in GUI

You can get it simple.

1. Open the Terminal
2. Type in: ifconfig

I am looking python script with GUI that can get IP address of Pi automatically

any idea how it can be done

Fan174

The relay you show has a 5V coil. You cannot (easily) use that to monitor a 24V supply. The relay contacts (output, to Pi) are on the blue terminal block. NC and NO are labelled, the third will be COM. I can't read the labels on the pin connector for the coil (input) side. There are three signals (...

Your code is written to look for a falling edge but your relay is wired with a pull down on the gpio pin. so you have 2 choices change you code to GPIO.add_event_detect(channel, GPIO.RISING) . I have modified my code from time import sleep import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) ...

What may be wrong from time import sleep import RPi.GPIO as GPIO import time GPIO.setmode(GPIO.BCM) GPIO.setup(16, GPIO.IN) def callback1(channel): print("interrupt detected") GPIO.add_event_detect(16, GPIO.FALLING, callback=callback1, bouncetime=2500 ) if I sort pin 16 it give interrupt detected I ...

I have been tried to run the example project for pi camera but I couldn't get success I tried in this thread https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=228108&p=1399332#p1399332 but here program is not working anyone have a working program? I just want to test camera to scan barcode

Fan174

Should be OK but you probably will want a pull down resistor on the GPIO pin 7. I think I can set pull-down resistor in program 1. Will work OK if the relay and RPi are not too far apart. Expect problems if they at opposite ends of the house. 2. Depending on what the RPi is destined to do with the ...

I think I can set pull-down resistor in program

Code: Select all

GPIO.setmode(GPIO.BOARD) # Use physical pin numbering
GPIO.setup(7, GPIO.IN, pull_up_down=GPIO.PUD_DOWN) # Set pin 7 to be an input pin and set

I want to connect relay as input for raspberry pi.

can we connect as shown here

Will it damage to raspberry Pi ?

If you want something to happen (send an SMS) based on the GPIO pin, you'd need to add code to the "FAULTbuttonPressed" function which is called by the GPIO callback. You don't need an "if" when you are using the "add_event_detect" method of the GPIO library. At the moment your code just sends the ...

Does this work? I've tested as much as i can without actually making the urllib request.

I testd,It gives this error
