I wanted to write to my public channel 2278931 with 8 different values to 8 different gauge widgets.
Here is my link.
https://api.thingspeak.com/update.json?api_key=xxxxxxxxxxxxxxxx&field1=1&field2=2&field3=3&field4=4&field5=5&field6=6&field7=7&field8=8
You can change values and in the link to change gauge values. On edit I edited my write key to make it not work for others but it will work with your own key.
Up until a few weeks ago, there was a "channels shared with me" option in Thingspeak. I was able to access the channel created by a different user, only once. The next time me and my groupmate tried to open the channel, there wasn't a "channels shared with me" option anymore. Why is that and how can this be resolved?
Thats the task:
Given a square cell array:
x = {'01', '56'; '234', '789'};
return a single character array:
y = '0123456789'
I wrote a code that passes Test 1 and 2 and one that passes Test 3 but I'm searching a condition so that the code for Test 3 runs when the cell array only contains letters and the one for Test 1 and 2 in every other case. Can somebody help me?
This is my code:
y = []
[a,b]=size(x)
%%TEST 3
delimiter=zeros(1,a)
delimiter(end)=1
delimiter=repmat(delimiter,1,b)
delimiter(end)=''
delimiter=string(delimiter)
y=[]
for i=1:a*b
y = string([y x(i)])
end
y=join(y,delimiter)
y=erase(y,'0')
y=regexprep(y,'1',' ')
%%TEST 1+2
for i=1:a*b
y = string([y x(i)])
y=join(y)
end
y=erase(y,' ' )
Is there any problem from thingspeak side, from last month my data is not uploading
That's the question: Given four different positive numbers, a, b, c and d, provided in increasing order: a < b < c < d, find if any three of them comprise sides of a right-angled triangle. Return true if they do, otherwise return false .
I wrote this code but it doesn't pass test 7. I don't really understand why it isn't working. Can somebody help me?
function flag = isTherePythagoreanTriple(a, b, c, d)
a2=a^2
b2=b^2
c2=c^2
d2=d^2
format shortG
if a2+b2==c2
flag=true
else if a2+b2==d2
flag=true
else if a2+c2==d2
flag=true
else if c2+b2==d2
flag=true
else flag=false
end
end
end

Currently, I am trying to setup MATLAB and Simulink to connect with Unity. But I have some questions about the installation of ROS on my computer and ROS Toolbox. I found that there are several ROS installations, so, could you please kindly help and support? Hoping that your support will help a lot to my master's thesis.
i want make web site for pre registation to the vachile in thish project i can not thinke how to register in port and how to make .....????
i want make uniqe project
That's the question:
The file cars.mat contains a table named cars with variables Model, MPG, Horsepower, Weight, and Acceleration for several classic cars.
Load the MAT-file. Given an integer N, calculate the output variable mpg.
Output mpg should contain the MPG of the top N lightest cars (by Weight) in a column vector.
I wrote this code and the resulting column vector has the right values but it doesn't pass the tests. What's wrong?
function mpg = sort_cars(N)
load cars.mat
sorted=sortrows(cars,4)
mpg = sorted(1:N,2)
end
Hi! Actually I'm trying to store data from 5 sensors on the ThingSpeak cloud. I was able to do it 2-3 days back, but right now I'm trying to do the same for last 2-3 hours and it's just not happening. There's nothing wrong with the code because it's getting compiled properly. I'm using
ThingSpeak.writeFields(2261556,"xxxxxxxxxxxxxxxx");
I tried printing its value after storing in a temporary variable........The value comes out to be -301. Is there any fix for this? I need it urgently for a project.
I hope to receive some help soon. Thanks!

I've just bought a rain gauge with esp 32 but the problem is Its code is already programmed on esphome
Now I need to send the data to one of my channels so I can perform the logic for my sms API
Tell me if it's possible
Hi
We are using Raspberry Pi to send some sensor data to Thingspeak. Is it possible to send this data to any other IoT hub service lets say Thingsboard, AWS or Azure IoT hub? Does Thingspeak provide any kind of API which can give us alerts whenever the data is received in Thingspeak server ?
Thanks
I was unable to update fields during this time and was also unable to login to thingspeak.com.
Hi, is the timecontrol in matlab stop running around 1500 UTC+8 230809?
Hi I'm a newbie, the data I'm sending from the weather station I'm trying hasn't reached me for about 1 week.
Or rather, the data is sent regularly from the station to Thingspeak which connects and sends, but looking on the site it seems that they are not received.
The latest data received, in fact, dates back to 7 days ago.
By chance, after sending the 8000 available data, does the service stop?
Hi
I am a beginner in MATLAB. I am trying to stimulate RF energy harvesting. Is it possble to stimulate this using simulink? Kindly help me. Thank You.
im trying to draw a path for the aircraft. so the aircraft needs to avoid all the red zones in the radar image i have and should travel only on green zones even the waypoints are on redzones.

this the code im using. But according to the output im getting, the aircraft is still travelling through all the red and yellow zones.i have tagged the aircraft_icon.png and rada.jpg images which have been used in the code. can somebody help me out with this?
