NodeMCU comes fully equipped with an MQTT library, assuming you followed the build instructions in Part 1 of this series. However, this example also uses the DHT and DS18B20 libraries, so go back to the NodeMCU custom firmware build website and build...
For start, I will solder pins to LILYGO board and sensors. Once I saw sensor readings are working I've decided to transfer all this to perfboard, add all sensors that I mentioned before in this tutorial and let's connect everything to work as we want....

Dynamixel AX-12A: The biggest problem on controlling hexapod is controlling its leg, and that is what makes choosing motors the hardest job for component part. What I'm planning to do in the future for controlling this hexapod is using dynamic...
In this project, we will host a server on the ESP32 dev board, which will display Temperature, Humidity, Altitude, and Pressure from the BME280 sensor module. It is the same as LIVE Display of Data on ESP32but this time the file for Web Page can be easily...
This project provides full instructions, and time required is 7 days approx. Build instructions are described in logs: Step 1. Getting StartedStep 2. Communication Between Two MKR WAN 1300Step 3. LoRaWAN System Range TestingStep 4. Assembling the TransmitterStep...
The ESP32 microcontroller on the PCB is instructed to do the following: Read the accelerometers.Calculate the magnitudes of acceleration for the 4 x sensors.I did this in order to maximize the speed of data transfer to the PC, rather than send the 3...
Your hacked and sweetened Bubble Blaster is ready to go! Now you can incorporate it into any kind of project you want! Here's a list of some example projects I have done for inspiration! Hopefully i will get around to posting full how-to articles for...
In this project, we will host a server on the ESP32 dev board, which will display Temperature, Humidity, Altitude, and Pressure from the BME280 sensor module (You can use any other sensor to get environment data / Or use a randomized value to view data...
Here's what I did, i'll try to remember everything. -install raspbian on your sdcard, get the full release not the small oneplug your raspberry pi zero with some power and your wifi usb dongle. configure your pi so you can access it through your laptop...
A full current listing of the Octosonar class and methods is in the readme file at https://github.com/arielnh56/OctoSonar An important consideration is to make sure that you are coding your arduino as a "finite state machine". The class relies on your...
