The Arduino Melody Player with Speaker project becomes even more engaging thanks to the speaker from Adafruit. For example, the Mini Metal speaker offers high quality sound, so your melody plays smoothly. As a result, it is an essential component of the project. This compact and reliable speaker is perfect because it provides clear and…
The Automated Boom Barrier System is an easy way to control vehicle access. For example, it uses an ultrasonic distance sensor and a servo motor to open the barrier automatically when a car gets close. As a result, the system is flexible and works in many places. In addition, it is perfect for parking lots,…
Creating an interactive drawing demo with the ILI9341 Display is an exciting mix of hardware and software. For example, it shows the screen’s versatility, which is popular in many DIY electronics projects. In addition, the touchscreen feature lets users draw directly on the display, making it perfect for a fun application. As a result, this…
Starting a journey to create dynamic visuals can be exciting for people of all ages. For example, this guide is perfect for beginners who want to learn about animated OLED displays controlled by Arduino. In addition, Arduino’s user-friendly platform and OLED screens with clear, high-contrast visuals make animations easier than ever. As a result, you…
Electronics and robotics can seem complex at first. For example, understanding motion control can be challenging for beginners. However, the “Controlling Servo Movement with a Joystick Using Arduino Uno” project makes learning easier and more affordable. In addition, it combines a standard joystick input, an Arduino Uno microcontroller, and an SG90 servo motor to create…
A great addition to any project is the presence of audio effects. One of the best ways to integrate sounds into a project is the Adafruit Audio FX Sound Board WAV-OGG Trigger with 2MB Flash. Weighing at about 4.6 grams and sized at 22mm x 48mm x 6mm. Now, what makes this so easy to…
The bootloader is the program burned into an Arduino board and runs the moment the Arduino is powered on or when the reset button is pressed. This piece of code is what initiates the sketch that’s uploaded to the board. Another vital function of the bootloader is that it provides a means for the computer…
A recent project of ours involved using a sensor to detect when a small remote-controlled car hits an obstacle. What better sensor to use than the Adafruit LSM9DS0, a sensor-equipped with a 3-axis accelerometer. There are a few alternative sensors available with the concept of detecting impacts, especially when used on a small scale. Of…
In this tutorial, we are going to explore the pre-installed AT firmware inside the ESP8266. The AT Firmware The AT firmware is a pre-installed software in the ESP8266’s ROM (Read-Only Memory). It uses AT commands which are based on the Hayes Command Set. The Hayes Commands Set are commands for telecommunication operations. For instance, dialing…
Quite often, we want to place our sensors at locations where we have no access to a power outlet. The obvious solution is to add some solar panels and batteries to your project to make it run 24h / 7 days a week without the need to recharge it.
