QUESTION
I have a bme688 sensor (from Pimoroni) connected to a RPI ZERO. I have the PAHO MQTT library so I can send the data to the broker.
If you see code below, in the very last line, I have a "time.sleep(5)". The code below works perfectly well. It takes the readings and sends them via the MQTT. The problem I have is that if I change the time from 5 seconds to 300 seconds (10 minutes), the MQTT does not seem to send the data. The RPI ZERO has the raspbian desktop installed so I ran it using Thonny to see if I get an error but everything works fine with the 300 second delay... but it does not send the data across to the broker.
Any thoughts?

Answered 2021-Jun-07 at 22:22The setPlaying call causes re-rendering and initializes a new instance of Audio every time the component re-renders, you'll have to call useRef to persist the Audio instance between each render:
QUESTION
I have been making an Atari Breakout inspired game based off of a tutorial. I was wondering how to make a "GAME OVER" screen that will show up once the player dies. The code that I have has a variable that I created called "DrawDeath()". I have it coded so that text appears when you die but for some reason it never shows up.
...ANSWER
Answered 2021-Jun-04 at 21:19You have some errors in your code so I correct what the console showed. I have also changed the code to use requestAnimationFrame. Once a gameOver status has been triggered the requestAnimationFrame will stop running and setInterval will run the drawDeath function. You also have an error in your game over text as you were missing the x and y coordinates.
Additionally I added the downPressed variable that was missing so you could restart the game.

QUESTION
Im not sure why but I cant seem to get this footer to go properly to the bottom, my body seems to only be going halfway up the page? I wrapped the whole thing in main to see if that would fix it if I set a height on that, it seemingly only goes the same height every single time. Its like its not catching the viewport or something and causing it to only go about half way up. Also please be easy im a new coder so if your awnser has just general advice to improve im all about it. Thanks ahead of time!
...ANSWER
Answered 2021-May-24 at 00:16The line max-height: 100vh in #tribute-info is the cause of this. If you remove it, the footer will display correctly at the bottom.

QUESTION
I am trying to make a planner. I have a table which I want to be something like this:
ID Parent ID Start Date Duration End Date 1 01/01/2021 10 11/01/2021 2 1 06/05/2021 2 08/05/2021 3 2 08/05/2021 1 09/05/2021 4 3 09/05/2021 5 14/05/2021 5 2,3,4 14/05/2021 4 18/05/2021The Start date will be based on matching the Parent ID to the Task ID, so task 2 follows task 1, task 2 follows task 3 etc. I also want to be able to test against multiple tasks that might be happening at the same time, so task 5 can start after tasks 2, 3 or 4, which ever ends last.
I wrote this UDF for the start date calculation.
