[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.

decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield.

It has a distance sensor to calculate the distance ... Hu whether Sparki comes with a standard Arduino board and, if not, how someone might go about building one of their own.

“In this Instructable we’re going to build a budget spinning LiDAR sensor, powered by Arduino. It cost less ... and hence angular interval between distance measurements.” ...

The $87.36 Arduino Plug and Make Kit comes with an Arduino ... a strip of dimmable LEDs, a movement sensor, a time-of-flight distance sensor, a buzzer, a thermometer and humidity sensor, and ...

At the heart is an Arduino compatible microcontroller ... And, since the Electric Paint can also act as a proximity sensor, you could potentially build a dimmer that brightens the room as you ...
