Ultrasonic Rodent Repeller Battery Powered

In recent times, ultrasonic rodentrepellerbattery powered has become increasingly relevant in various contexts. Make your own ultrasonic theremin with Arduino | Freetronics. Arduino enthusiast Alberto Bietti has created a simple and noisy project based on an Arduino board - his ultrasonic theremin. This is a type of musical instrument that can be played without any physical contact, thus the ultrasonic sensor which measures the distance between itself and an object.

Building on this, dIY ultrasonic garage parking helper with Arduino | Freetronics. Instead of resorting to the tennis ball and fishing line, Instructables user "Aptpupil" created a device based around an Arduino circuit and an ultrasonic distance sensor. Furthermore, make garage parking a breeze with Arduino | Freetronics.

It's important to note that, using an ultrasonic distance sensor, it feeds the vehicle's position relative to the wall to an Arduino (or ATiny) which then articulates the data using an RGB LED. You can program in the required distance and then when you're close the LED will change colour. Build an Ultrasonic Parking Distance Aid | Freetronics. Moreover, created by Jin Choi the hardware is very simple - consisiting of an Arduino-compatible circuit, an inexpensive ultrasonic distance sensor and some bright LEDs. The sensor is directed towards the vehicle's approach direction and flashes the LEDs in various ways to indicate how far the bumper is from the wall or other object. Build a garage parking sensor with dashboard readout using Arduino.

From another angle, many vehicles are fitted with ultrasonic sensors that let you know if you're getting too close to a wall or pedestrian, however the actual distance is not given. Experimenting with Arduino and Ultrasonic-radar - Freetronics. One example of this is to build a simple "radar" style device, and this has been demosntrated by Ujash Patel with great success. Furthermore, by using an inexpensive ultrasonic distance sensor mounted on a servo, it can be rotated over the range of the servo and a distance taken for each degree. Build a wireless fuel tank monitor | Freetronics.

The levels in the fuel tank are taken with an ultrasonic distance sensor, and the volume of the tank can be determined by the level of the fuel and geometry in the Arduino sketch. The sensor side of the project also runs using very little power, thanks to the Arduino LowPower library. Modifying cheap robot toys with Arduino | Freetronics. In this context, david found one for himself, and modified it with a larger battery, small Arduino-compatible board and an ultrasonic sensor for obstacle avoidance. Here it is in action: The key to these modifications is to find something that has simple, direct controls to the motors or a recognisable motor control IC.

DIY Arduino-controlled Miniature Elevator | Freetronics. However the car location is determined by the use of an ultrasonic distance sensor at the bottom of the "shaft". It's not too difficult and a lot of fun, for example: Build an Arduino-controlled Ultrasonic Rangefinder | Freetronics. It's a neat project that rotates an ultrasonic distance sensor across a 180-degree sweep, and displays the result on a small colour OLED display.

This has many uses, from simply being a lot of fun to experiment with it also gives you the framework for a more advance object-detection system for an autonomous robot or artificial-intelligence project.
