Metal Detector
Luna Ramírez Dec 13,2024
This metal detector is based on the principle of frequency displacement when a magnetic material is close to the oscillator coil.At first the microcontroller gets the frequency of oscillation, when the frequency change it lights one to four leds, according to the displacement amount.

Ultrasonic Sensor HC-SR04 Interfacing with Arduino
Jain Dec 12,2024
The HC-SR04 Ultrasonic Sensor is a widely used and easy-to-implement sensor for distance measurement. Known for its high accuracy and stable readings, it has a range of 3 cm to 300 cm. This makes it an essential component in a variety of projects such as obstacle-avoiding robots, object detection, burglar alarms, smart parking systems, and more.In this guide, we will delve into the working of the HC-SR04 ultrasonic sensor and learn how to interface it with an Arduino Uno.What is the HC-SR04 Ultr...

DIY Simple Antistress and Relaxation PEMF Device based on Schumannn resonance frequency 7.83 Hz
Pavleski Dec 12,2024
 Schumann resonances are global electromagnetic resonances, generated by lightning discharges in the space formed by the Earth's surface and the ionosphere. The primary frequency of Schumann resonance is around 7.83 Hz and has several harmonic frequencies, including 14.07 Hz, 20.25 Hz, 26.41 Hz, and 32.45 Hz. Multiple studies suggest that the Schumann frequency of 7.83 Hz positively affects human health and well-being. It has been linked to improved cognitive functions, reduced stress ...

LS30 Rotary Joystick to USB Keyboard Adapter
Reboot Dec 10,2024
Plug in the 13 pin cable from 1 or 2 LS30 style arcade Rotary Joysticks and this board will send out keyboard keystrokes over USB to indicate when each joystick rotates clockwise or counter clockwise.This allows emulators to use the joystick as a game control input.The PCB contains an ATMega32u4 and behaves like a Pro Micro.Since the manufactured PCBs will contain blank chips, the board must be flashed with a Pro Micro bootloader.Then it will appear as a serial port in the Arduino IDE like a Pr...

TinyDRV - a MUST-HAVE add-on for N20 DC motors
Haase Dec 02,2024
N20 motor brushes are hard to solder, and you always need an external motor driver which takes up a lot of space and is often inefficient, like the L298N or TB6612FNG. The TinyDRV is here to solve both of these problems. It integrates a tiny 4 amp, 2 to 10V motor driver, ESD protection, and LED indicators to tell you which way and how fast the motor is going. If you don't want the LED indicators for low-power consumption (which this thing is great at, by the way), you can just cut the solder jum...

DIY simple HUNTER Led Game with Arduino
Pavleski Nov 28,2024
 Some time ago I presented you a simple to make, but interesting game, a 1D version simulation of "Pong game" made with Arduino and 10 LEDs. This time I'm going to use the same hardware with minimal pinout changes to show you how to make an equally fun and addictive game known as "Hunter". The goal of the game is to press a button at the moment when a pre-defined LED is lit and we get a point.This is a modified version of the Hunter, with two LEDs marked as the target. The Target LEDs are B...
