7 segment addresable huge PCB

This is a 7 segments display project. I say huge because is way bigger than comon 7 segment displays. Also, it is addressable so we can control a lot of themn in series using just one pin of the microcontroller and the Adafruit library.

Radio chat with my Keyboard PCB

I've used my keyboard PCB from a previous tutorial and made a simple chat between two arduinos with radio connection. A quite fun project to make and use. See more...

DOT MATRIX BLUETOOTH & CLOCK

I've remade this project. We have 9 dot matrix modules in series. We could scroll text sent from the smartphone via Bluetooth, we can show time from a RTC and the full date. Chaenge speed and brightness. See more...

NRF24 small receiver board

This is a very small NRF24 radio based PCB. It has 4 H bridge outputs and one MOSFET output so you could control 4 motors for a RC toy car, a drone or RC plane. See more...

Arduino HUGE Tetris game with WS2812 RGB LEDs

I've made a new project with the colorfull WS2812 RGB LED strip. Is very easy to use. In this case I've made a huge Tetris board game with sound, score and joystick control. See more...

Arduino serial KEYBOARD - full alphabet

I've made a PCB with the full alphabet and with matrix format with serial output UART or i2c. It hass all the characters, numbers and special signs. See more...

Brushed DC motor, Optic encoder PID control of Axis

See how to control a DC BRUSHED motor with PID and move a CNC axis with Arduino and an optic encoder in quadrature. Move the motor with H-bridge circuit. See more...

ESP8266 webserver control IoT

Control sensors, LEDs, modules, anything connected to an Arduino from anywhere in the world using a server database and a small interface and the ESP8266 WiFi module. See more...

PID Balance+Ball | full explanation & tuning

A better way to see how PID works. See how to control the position of a pingpong ball with this balance controlled with Arduino, PID and a servo witha distance IR sensor. See more...

DIY 5 in 1: distance, length, RPM, level, angle

In this tutorial we make a muti measurement device. It has a lot of sensor and a 3D printed case. It could measure distance, length, angles, level and RPM. See more...

Arduino 3D filament measure device

I've used a precision caliper to measure the filament diameter. This caliper has an i2c serial communication so we could get the data to the Arduino using just 2 wires. See more...

RC car PCB with NRF24 and BLUETOOTH

We now have the radio controller made with Arduino. We have seen how to receive data and control servos. Now, with this PCB we can control DC motors as well, add sounds and more extra stuff. Also, we have bluetooth control with an Android App. See more...
