Hi all, I have recently upgraded to debian 10 lite on a zero, I have been following this thread for a while as I wanted to attach 15 ds18b20s dtoverlay=w1-gpio,gpiopin=4 dtoverlay=w1-gpio,gpiopin=17 worked on stretch but does not work for me on buster :( so I tried dtoverlay=w1-gpio dtparam=gpiopin=...
Hi I had the same problem, So I changed my python code from if read_sensor(sID1) + x > read_sensor(sID2): GPIO.output(25,GPIO.HIGH) # print("it's Hot!") To if read_sensor(sID1) + x > read_sensor(sID2): GPIO.output(25,GPIO.LOW) # print("it's Hot!") And now the relay woks :D
I am asking the impossible!
So I decided to look at this another way, I have set up a flask server and i can now display the out put of both DHT11 and DS22b10 sensors, I will get back soon with the code when I understand it
The relay is connected to the 5v from the Pi? Which part of the relay? Are you able to post a pic or diagram of how you have connected it. The 5v pins are not switchable, they cannot be controlled from software. I've just found this thread on the Forum which may help: viewtopic.php?t=197339 Hi Forr...
Thank you for your reply, It is pluged into the 5v output of the pi, I think the problem is my script so I am working on this side of the problem.
Thanks a gain for taking the time to look
I had at the end of the script the cleanup line,
If I wire up the test lamp to the left it works, so the bright red light must mean the output is LOW , I am sorry but I need a little bit Of help
Hi again I edited my script and... Whilst the script was running the little red light went out, when I stop the script the light is still out, I unplugged the pin and replugged it in the light is now bright red! Is all this normal, I Hve read i should put a clearup script at the end but not to sure ...
Hi all I am trying to build a home heating control, my first step is to control a solar heating panel I built, I want to turn on a circulation pump when the panel is five degrees hotter than the hot water tank and turn off when they are same temperature. I am running a pi zero with rasbian stretch l...
Hi I have read through the last few pages of this post, but I cannot find the answer to my problem, I want to post the temperature and humidity to a web page with a simple php file. I am using a pi zero w 4gb disc stretch lite php7 apache2 mariadb, I have one DHT11 but would like to use two, I have ...
Hi again MrEngman I updated my kernal and rebooted and lost internet, my dongle does not work any more, I have stuck the sd card into a zero w and have tried the following script sudo wget http://www.fars-robotics.net/install-wifi -O /usr/bin/install-wifi sudo chmod +x /usr/bin/install-wifi sudo ins...
If I understand correctly, I put the pi sd card into my scratch machine and use the code you are very kindly going to give me, and then this will enable me to then install this and make every thing work?
Hi I have the same problem but no Internet access from my zero without the dongle uname -r = 4.4.50 I followed the code below, but as I have no Internet, no joy. sudo wget http://www.fars-robotics.net/install-wifi -O /usr/bin/install-wifi sudo chmod +x /usr/bin/install-wifi sudo install-wifi -h My l...
