Ringo by CircuitMess Library.The package includes some header pins, a battery connector, and an external antenna that you should connect to your board. However, we had some issues with that antenna, so we decided to switch to another type of antenna and all the problems were solved.

The following figure shows the new antenna. The idea of this project is to publish sensor data from anywhere to any cloud service that you want. If you want to follow this exact project, you should follow that previous tutorial first to prepare your own server domain. Then, upload the code provided in this project to your ESP32 board. If you want to follow this exact project, you should follow the next tutorial to prepare your own server domain.

You need the domain name, username and a password. So, you might need to contact them directly. Follow the next instructions to install these libraries.

The Library Manager should open. Follow the next steps to install the library in your Arduino IDE:. Scroll all the way down to find the library and install it. You can use the preceding links or go directly to MakerAdvisor. First, you need to make some modifications to make it work. View raw code. In our case, the APN is internet. Yours should be different. You also need to type the server details in the following variables. It can be your own server domain or any other server that you want to publish data to.

In this case, the apiKeyValue is just a random string that you can modify. In the setupinitialize the Serial Monitor at a baud rate of Because the ESP32 will go into deep sleep mode at the end of the loopit will only run once. Basically, we create a string with the API key value and all the sensor readings. You should modify this string depending on the data you want to send. Finally, press the upload button to upload the code to your board. First, the module initializes and then it tries to connect to the internet.

Please note that this can take some time in some cases it took almost 1 minute to complete the request. In this example, it publishes new sensor readings every 60 minutes, but for testing purposes you can use a shorter delay.

You should see the charts with the latest sensor readings. We hope you liked this project. You can connect your board to the internet quite easily using a SIM card data plan. Muito Obligado Rui, thanks very much, can we see in a video how do you insert the SIM card in the board?

Also an idea, what about a simple app using app. Hi Tomas. So, stay tuned.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

They also include a LiPo battery charger and two buttons one is wired to reset, so it isn't as useful. It looks like they hacked up the Adafruit library to make their own.

The other libraries should be pre-installed, such as the Preferences to access the ESP32 non-volatile storage, and the Wire library for i2c communication. Be sure to note that the components are turned around if you plan to try both modules. There doesn't seem to be any discussion of it in the SDK, nor is it described with pin needs to pull-down.

The reset pin on the OLED needs to be controlled by the sketch. It does not seem to be included in the library. Pin 16 is the reset line and it should be brought low for a few ms, then held high the entire time the screen is to remain on. This should be pushed upstream. Skip to content.

On checking the dead module, if I power it from the USB port, all the 3. Do you have any thoughts before I fry another module.

Thanks for your excellent projects and advice. Hi Peter. However, what might have caused the issue is the battery connected to the ADC inputs. I think these pins are only 3. Regards, Sara. I think my best plan is to protect the sense voltage input with a zener diode at 3 volts and use a linear regulator rather than a buck converter to power the module.

Yes, 18V will kill the module. There are some buck converters that you can regulate using a small potentiometer. If you are not careful you may get more volts that your board can handl.

The campus I work at is shut so I have had an extra long weekend — perfect for some hacking! Many ESP32 dev boards have an onboard OLED display included — at first glance these are hideously undocumented in every way, many are clones of clones coming from the techno world of the East with little to no information about use or origin, and often from sellers who may not speak much English as their first language, or understand the hardware they are selling!

If you pick something up with a clear silkscreen guide then you are already in a good place. This is a pretty average serving from the sea of ESP32 dev boards in terms of the information provided — there is very little! But at very least, there is a pin IO map which covers most stuff pictured below. Amazon UK. Ebay UK. Banggood CN. In this tutorial, I will show you how to display a couple of basic things on the screen using an external 3rd party library from ThingPulse.

I am going to use the Atom text editor with the PlatformIO plugin in this tutorial because I think it is much easier to get started with ESP32 this way if you have a basic understanding of Arduino — I also think it is superb and multipurpose dev environment.

In the near future I think it would be good to do something a little more interesting with this board — as the ESP32 is an IoT ready device with onboard WiFi and Bluetooth, we want that screen displaying something more interesting like a feed from ThingSpeak. I will walk you through them. In our case, and in most cases the CP is used. You can download a package to install the driver from here. I am not going to go through this process in detail because I already know an excellent video tutorial and I am pretty new to the IDE myself.

TTGO T-Call ESP32 SIM800L – Power Supply Question

Save the folder somewhere sensible on your harddrive — as the repository is effectively an Arduino library, a good place to put it would be your Arduino libraries directory, usually found under Arduino in your Documents. On the home page, create a new project — I want to point out my one frustration with PlatformIO here — file management. When you create a new project, make sure you save it in a new folder it is frustratingly easy to not do this. Now we can get started.

PlatformIO should have opened your new project folder — if you are new to the IDE, notice that you deal with a couple more files than you do normally with the Arduino IDE — to get started, click on the src folder and then click on main.

You should see a short OLED demo play if it is the first time you have powered the dev board on. First, we need to install a library for the OLED display — the display has an SSD driver behind it, so we want a library that can talk to that. Installing libraries for PlatformIO is easy, but I missed it at first.

There is a tab on the PlatformIO home screen in Atom that contains all the library management you need. Did it work? Now is a good opportunity to try the different font sizes and alignments — and try printing with different x, y origins. You can prepare multiple display. Also, try adding a delay ; after display. Try the adding the code below to main. The outer for loop just repeats the inner loop 3 times, the inner for loop repeats times.But every now and again you need to do a bit of head-scratching.

But these boards would be far more compact. But I hit a snag right away. You can always write your own code to control the display. And there are many libraries out there for the SSD none of which I got to work. It turns out, that information is out of date — the library has been updated to allow it — but I had to dig down into comments on forums to find this out.

I find that library examples like this are always a good starting point in understanding both libraries and the devices they support.

First, the simplest. In the Adafruit library example code, it has pin 4 set as the reset pin for the display. We need to change that to The default code looks like this:.

Note the 0x3D parameter. If we used the display. So we need to begin our TwoWire instance with the correct pins before we get to display. So the altered code looks like this:.

But, when I added the update sections above two pars and a pictureit added them four times to the post. And it moved one of the original paragraphs and not even the last one to the bottom.

I tried switching back to the block editor, but things just started going downhill. And it added more copies of the additional section. So back to the classic editor and a few minutes stripping out all the formatting tags the block editor had added to the post. This is classic feature bloat. What was a perfectly fine editor has been replaced with something not nearly as clever as it thinks it is. And buggy as hell. So much for progress. Hey, My name is Philipp. The part:.

I think I have to do edit something more than just copy that into my code right? You you this might be self evident The four include lines have turned up blank — maybe because WordPress has treated anything between angle brackets as HTML code!
