hello… I want to do a project on fire alarm with minimum and maximum limits by adding buzzer and LED light. I want someone to check my code
I am getting a continuous output without gap.
I am getting a continuous output without gap.
What is the issue in program? It is reading continuously, so you want to delay the process?
I see error in your circuit connection too.
- LED pins are connected incorrect.
- The resistor for buzzer is short circuited, so the buzzer will never take the route through the resistor. It’s pins are on the same line, like a parallel connection (with the wire from the buzzer and the one connected to pin 2.
Yea it is reading continuously… how to delay the process?
and I made changes in my circuit connects as well
time.sleep(10) --> here 10 means delay the execution for 10 seconds. So you can calibrate according to your needs.
And, suggestion -
- print “Reading sensor value” outside the while loop.
- remove either of the print statement “sensor value is”. Either the one inside try handle or the one outside.
hello!!
Now I am not getting a telegram message when the limit reached threshold… can you please check it once
Check whether the telegram credentials are correct. The chat_id and bot_id have to be correct without any mistake. It happens as we keep zero ‘0’ instead of letter ‘O’ or viceversa in the bot_id. So check the credentials.
Correction - print("status of telegram message is:", telegram_status)
Check your telegram credentials, as we discussed earlier as well. You had a typing mistake last time.
Incase, you get the error again after you can create a new bot and add the bot token, that should work fine.
Let me know if you need any other information.
