It is a tiny ESP board that has an ultrasonic distance sensor and ... trading Arduino for ESP8266, and doing some 3D printing to fit the sensors and switches, and Samer Albahra providing mobile ...

When you think of Arduino projects ... on how far your hand is from the ultrasonic sensor when you activate it with the force-sensitive resistor. The closest distance corresponds to C, the ...

The SparkFun Ultrasonic Distance Sensor - TCT40 (sen-24805) a user-friendly upgrade to the popular HC-SR04 sensor, offers non-contact distance measurement from 2cm to 400cm with an accuracy of 3mm.

calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research comprises an ultrasonic sensor module, an Arduino Uno ...

In our paper, the sensor will not send a signal until the car is 1 meter away from an obstacle. Several warnings exist. The system alerts the user of the distance remaining by ... written in C++ and ...

In the present work, we have used Arduino UNO and ultrasonic distance sensor HC-SR04 to measure distance of freely falling body at different intervals of time. Software’s like Microsoft Excel, Origin ...
