 # Wifi_twit.py changing Celsius to Fahrenheit and changing frequency of tweet

Hello Dexter Community. I’ve been working with the wifi_twit.py project and have almost everything up and running. But I have two questions:

1. How do I get the code to output the temperature in Fahrenheit instead of Celsius?

2. How do I make the code tweet less frequently?

Thank you!

Hi @mremingtonb,

How do I get the code to output the temperature in Fahrenheit instead of Celsius?

The formula for converting `Fahrenheit` degrees into `Celsius` degrees is the following:

1. Multiply your `Fahrenheit` value by `9`.

2. The result is divided by `5`.

3. And at the end add `32`.

If you want to go the other way, like convert from `Celsius` to `Fahrenheit` degrees, you just need to reverse these 3 steps.

How do I make the code tweet less frequently?

I’m not sure what you’re referring to since I don’t have any code to look on. Maybe you can share it with us and we’ll give you some advice.

My first impression is that you need to add a `delay`, or a `scheduler`. It totally depends on your setup.

Thank you!

Thanks for the reply Robert! I know the formula for converting between Celsius and Fahrenheit, I just don’t know where in my code to put that formula to make it display in Fahrenheit instead of Celsius. It displays in Celsius by default.

I figured it would be something like x = (x * 9/5) + 32

But I’m not sure what x is, nor where to put it in the code.

Anyway, as to that, and as to tweeting frequency, here’s the code:

import time
import grovepi
import math

# Connections

sound_sensor = 0 # port A0
light_sensor = 1 # port A1
temperature_sensor = 2 # port D2
led = 3 # port D3

intro_str = “DI Lab’s”

consumer_key=‘YourKey’,
consumer_secret=‘YourKey’,
access_token_key=‘YourKey’,
access_token_secret=‘YourKey’
)

grovepi.pinMode(led,“OUTPUT”)
grovepi.analogWrite(led,255) #turn led to max to show readiness

while True:

``````# Error handling in case of problems communicating with the GrovePi
try:

# Get value from light sensor

# Give PWM output to LED
grovepi.analogWrite(led,light_intensity/4)

# Get sound level

time.sleep(0.5)

# Get value from temperature sensor
[t,h]=[0,0]
[t,h] = grovepi.dht(temperature_sensor,0)

# Post a tweet
out_str ="%s Temp: %d C, Humidity: %d, Light: %d, Sound: %d" %(intro_str,t,h,light_intensity/10,sound_level)
print (out_str)
api.PostUpdate(out_str)
except IOError:
print("Error")
except KeyboardInterrupt:
exit()
except Exception as e:
print("Duplicate Tweet or Twitter Refusal: {}".format(e))

time.sleep(60)``````

Hello @mremingtonb,
• change the last line from `time.sleep(60)` to `time.sleep(3600)` where the number is how many seconds between tweets. The first one is once a minute, the second one is once per hour.
• after this line: `[t,h] = grovepi.dht(temperature_sensor,0)` add
