I'm just a simple man who loves electronics. I live in Spain and I've studied electronic engineering in UB, University of Barcelona. ELECTRONOOBS all started as a simple Instagram account where I was posting all my daily projects and homework. I soon started working on this webpage where I’m currently posting new tutorials every day. As you can see, there is a bit of everything. Electronics with Arduino, basic circuits, robotics, 3D printing and so on.
Later I’ve made my first YouTube channel called ELECTRONOOBS as well. Next, I’ve made my second channel just for Spanish projects and blogs. I hope that you will enjoy my webpage and everything that I do. You can check my Patreon page and help my projects. ELECTRONOOBS also has a Q&A forum page where you could post your question and me or anyone else could answer it. Thank you very much!

Here you will find all my Arduino basic tutorials. Modules, codes, projects, communications and everything based on the Arduino technology. Learn Arduino step by step. LINK
Here you will find a lot of basic circuits tutorials such as the H-bridge, speed controllers or bost/buck converters. This are just some of the examples, visit for more. LINK
Here you will find all my Robotics tutorials. Make your own RC tank or plane. Create a drone. Learn about PID control and a lot more. Visit the Robotics page for more. LINK
We've made an inverter before but with a square wave output. Now we look how SPWM works and get a sine shape output for the inverter. Read more
This is another Arduino and NRF24 based radio controller. But now with better joysticks, OLED screen and digital fine tune. It also has a 3D printed case. Read more
I'm building an electric longboard with powerful brushless motors, 3D printed case, homemade 6S battery pack, radio controller and much more. Read more
I've made another pwoer supply since the last one was not a success. This time I'm using an LCD with i2c so the code will be faster. Read more
This projects uses the ADS1115 and it could measure resistance, capacitance, inductance, current and voltage with good precision. Read more
I've designed a 3D printed case for the electric screwdriver, it uses a DC motor with gear system, H bridge to control rotation and a Li-ion battery. Read more
I've been working on an Arduino based smartwatch that could show time, date, alarm, temperature, connect to a smartphone via Bluetooth and show notifications. Read more
Finally, the board works perfect. So I could make a 3D design for the case and this is a final product that could end up on Kickstarter. It is a very cheap project, around 15$ for all the parts.
This board use a 433Mhz radio connection and an ATTINY 85 chip, so everything is very simple. It has only 4 “digital” channels so we can’t really use it with drones for example...
DIY portable soldering iron V3.0
Now we can solder the remaining components such as the vibration sensor and the side push buttons. The board I've made didn't had the wings pads for the buttons, that's why I've put some hot hlue behind the buttons. But the final GERBER file has the wing pads for the buttons so solder those as well. Next we solder the clips for the T12 tip. Make sure the clips are on the bottom side.
Arduino brushed motor DRONE tutorial
Go step by step and build the ultra low cost drone using some wood sticks, the Arduino, the MPU6050, NRF24 radio modules, the old radio transmitter and last but not least, the cheap brushed motors.. Read more
DIY Smartwatch + Bluetooth
I've been working on an Arduino based smartwatch that could show time, date, alarm, temperature, connect to a smartphone via Bluetooth and show notifications. I had some errors on this baord, but in this tutorial, I'm sharing the good board that I've already fixed. See below all the files, the GERBERS, the code and a step by tep tutorial. Lets start!
HOMEMADE ELECTRIC LONGBOARD
I've started a new project. I want to make my own homemade electric longboard with a powerfull Brushless motor. The first idea was to use two motors, but I had not enough space between the wheels of my longboard. In this tutorial we will see how to mount everything together, make a test and give the final results. Make sure you watch the tutorial on how I've made my homemade 6S battery pack in order to finish this tutorial. Read more
