I created this small Christmas Village for my little monster.

In this tutorial we will learn how to make a simple step counter. This project is very useful in robotics.

12v to 5v convertor

Today I built with Arduino a simple game for 2 players. Each player have to spin the wheel and the winner is the player that scores higher!

Design of an indicative featured and speed controlled obstacle avoiding robot.

This is the start of a new series where we learn how to build a dashcam using the Raspberry Pi Zero.

A smart city is an urban area that uses different types of electronic data collection sensors to supply information used to manage assets.

ESP32 + HTTP server + WebSockets + Bootstrap + Husarnet + configuration and HTML files on SD card.

We take a look at a very interesting GitHub repository that enables video recording on the ESP32-CAM board.

we performed the control of the stepper motor in the forward and backward directions along the x axis with the joystick

RGB LED backlight with audio signal visualization for room/desk backlightning...

Build your own line following robot (line follower) step by step easily by following this tutorial

When the reset button is pressed, the board will take an image, store it to the microSD card and it will then go back to deep sleep.

How to connect A6 GSM GPRS module with Arduino and also work with “AT” commands.

DigiSpark ATtiny85 I2C connected to a tiny OLED (128x32 pixels) can show easily readable, huge fonts (16x32 pixels WxH)!

This is the 2nd tutorial on my ESP32 learning journey. Here, an OLED shows time and captured data by DHT sensor (temperature & humidity).

This is the first post in a new mini-series, where we build a home surveillance system, mainly using Raspberry Pis.

Application notes for Pmod CMPS2 and Arduino Uno. The 3 components of the magnetic field, module, & angle are displayed in serial monitor

Exploring the signals behind Arduino's Servo library, and characterizing a servo's response to pulse width.

I wasn't happy with the way the square waves sound, so I explored using other methods of generating sound waves with Arduino.

A discussion about digital sound synthesis.

Motor driver circuit with some power saving features.

The ability to process, manipulate and otherwise work with audio signals is a key feature of DSP in FPGA. Here's a look at how we do this!

The Cortex-M1 is ideal for implementations in low-cost FPGA Spartan 7 devices. Let's look at an example project.
