Then we sleep for 0.2 seconds, before turning the pin off and sleeping once more. Note that we use the variable led to identify the pin.
We will call the object board, with a class to control the pin digitally (0,1) and then write 1 to the pin to turn it on.

Inside of a while True loop, we can write the code that will turn the LED on and off every 0.2 seconds. You create it by adding the line: led = 12 board = Arduino('/dev/ttyUSB0')Ī variable called led is used to store the Arduino pin number. For this, we shall need to use the USB device information from dmesg.
The next step is to create an object called board that will be the connection from our Pi to the Arduino. We can then import the sleep function from the time library, by typing: from pyfirmata import Arduino, util Start by importing two classes from the pyFirmata library, which will enable our code to connect to the Arduino. We shall now write some Python code into this file. Using your favourite Python 3 editor (IDLE, Thonny, nano, Vim), create a new file and name it LED_test.py. Look for USB devices such as ttyUSB0 and ttyACM0. Plug in the Arduino, and in the terminal type the following code. Let me know if you have any doubts or suggestions to improve this code.Diagram showing how Arduino Uno connects to LED light. while alarm_tone thread is running, if user presses stop alarm or snooz button, I kill alarm_tone thread and in later case schedule alarm after 5 minutes. check_time function checks if it is time for alarm and if so it starts a thread to play alarm tone by running alarm_tone function. Once alarm is set I schedule check_time function to execute every minute. In main part of code, I created an infinite while loop which reads minute and hour data on pressing alarm set button and speaks it out for confirmation. I reserved two more GPIO pins, one for alarm start/stop and another for alarm snooz/reset.įollowing GPIO declarations, I created two functions. Going by similar logic I set aside 5 GPIO (24 out of 32 max binary digits) pins for hour input.

I decided to have resolution of alarm time to 5 minutes so we need only 12 binary digits to cover full 60 minute span and hence 4 GPIO pins (12 out of 16 max binary digits) for minutes. I used 4 GPIO pins as user interface to get minutes in alarm time.

Following that I used obtained IP address to access raspberry pi using ' ssh If you are on windows machine use software like putty to perform ssh.įirst I imported all required packages. I found IP address of raspberry pi using network scanning application named angry IP scanner.
Once configurations were done I took put SD card from my laptop and inserted it in to raspberry pi, followed by powering it up.
Once that was done I created an empty file named ssh in boot directory to enable ssh. Replace black stripes with your router's SSID and password. In order to get remote access I opened up interfaces file in /etc/network directory of root and used ' vim /etc/network/interfaces' command to edit it and made it look like one shown in image attached at #3. I don't have a monitor/keyboard/mouse to which I can connect raspberry pi but a laptop hence I enabled remote access to Raspi. Lets set it up.įirst I downloaded raspbian lite from, Installed etcher on my laptop and burned raspbian on an SD card. My speaking alarm clock is build around beautiful Raspberry pi zero W.
