This project is a simple automatic toll gate system built using Arduino, an ultrasonic sensor, a servo motor, and a 16x2 LCD display. The system detects when a vehicle approaches the gate, opens the ...

Local-first wins.

In this series I will be documenting my design and testing process for making a 3D printed arduino hexapod. This video sets up the basic premise of the project with a quick test of a servo controlled ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Soil moisture profile measurements are an integral component of water balance estimation networks, especially in thick vadose zones and fine-grained soil environments. At field sites with silty and ...

NEW projects in hilly areas in Ampang Jaya, Selangor, will be required to instal Early Warning Systems (EWS) as part of their development conditions. Ampang Jaya Municipal Council (MPAJ) deputy ...

Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

Python implementation of the SensorPush temperature and humidity/hygrometer sensors cloud API which supports both temperature (°F) and humidity (Rh) sensors. NOTE: Ideally SensorPush sensors would be ...
