Butterfly IQ – Ultrasound Anywhere, Anytime
https://www.electronics-lab.com/butterfly-iq-ultrasound-anywhere-anytime/
Ultrasound, also known as sonography, is a medical procedure which uses sound waves to get images from inside the body. It is used to help guide biopsies, diagnose causes of pain, examine a baby in pregnant women, diagnose heart conditions etc. High- frequency sound waves are transmitted to the body using a small transducer (probe), […]
Arduino Parking Assistant
https://www.electronics-lab.com/arduino-parking-assistant/
addictedToArduino @ instructables.com designed a Arduino based parking assistant. To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working with arduinos, leds, sensors, and nearly anything else electronic, so I knew from the start that it would probably end up […]
Alarm System Powered By Arduino
https://www.electronics-lab.com/alarm-system-powered-arduino/
Dejan Nedelkovski had built an Arduino security and alarm system project that uses an ultrasonic sensor for detecting objects and a buzzer for notification. Components needed to build this simple system are: Arduino board, LCD display, 4×4 keypad, ultrasonic sensor and buzzer. The circuit can be connected as shown in the schematics below. In order […]
How to Set Up an Ultrasonic Range Finder on an Arduino
https://www.electronics-lab.com/set-ultrasonic-range-finder-arduino/
circuitbasics.com has a new tutorial on how to measure distance using Arduino and an ultrasonic sensor. Ultrasonic range finders are fun little modules that measure distance. You can use them to find the precise distance to an object, or also just to detect when something is within range of the sensor (like a motion detector). Ultrasonic […]
Ultrasonic parking sensor
https://www.electronics-lab.com/ultrasonic-parking-sensor/
An ultrasonic parking sensor project from Ch00ftech: After electing to use the PING))) sensor exactly as directed, I needed to build the rest of my circuit. I wanted to build something robust that would mount nicely on the wall of my dad’s garage. Figuring that the sensor would likely need to be placed down low by […]
Ultrasonic Anemometer Project Progress
https://www.electronics-lab.com/ultrasonic-anemometer-project-progress/
Lukas Fässler discuss about his anemometer project progress and what tests he has performed so far. In the mean time I managed to do some rudimentary testing and now feel confident to take orders. These tests concern the hardware only. What I said last time about the state of the software still applies. But let […]
Arduino Proximity Alarm
https://www.electronics-lab.com/arduino-proximity-alarm/
Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for nearby objects and if need be, alert you with […]
Portable Ultrasonic Range Meter
https://www.electronics-lab.com/portable-ultrasonic-range-meter/
ManosM @ instructables.com has build a portable ultrasonic range meter based on ATMega328 mcu and LCD display. This device is a small, portable ultrasonic range meter using an ATMega328 microcontroller, an ultrasonic module and a 4×20 LCD for ranging distances in meters and inches. Portable Ultrasonic Range Meter – [Link]
Ultrasonic Atomizer
https://www.electronics-lab.com/ultrasonic-atomizer/
This reference design is a simple ultrasonic atomizer that helps fight against respiratory diseases. Atomizer is like nebulizer, it is just that nebulizer takes time to deliver liquid to mist. However, both undergo almost the same process. This medical ultrasonic atomizer circuit is composed of power supply circuit, ultrasonic oscillator and atomizer circuit. It specifically […]
HC-SR04 Ping Sensor Hardware Mod
https://www.electronics-lab.com/hc-sr04-ping-sensor-hardware-mod/
by cascologix.com: HC-SR04 ultrasonic sensor modules, also commonly called ping sensors, are practically a dime a dozen, with many Asia online retailers selling them in the $2 to $3 dollar range each. While possibly not intended for an end solution or product, these sensors offer a more affordable option for prototyping and application development compared […]
