PID-based one-axis ball balancing robot using Arduino. Uses an ultrasonic sensor and servo motor to stabilize a ball at a target distance. Real-time tuning of Kp, Ki, Kd via Serial. Includes stability ...

Arduino Nano H C-SR04 ultrasonic sensor SG90 servo motor 1.8″ ST7735 Display (or equivalent) Soldering kit Screwdriver set 9V battery and connector Electrical wires and soldering gear.

This paper shredder bin monitor is an easy Arduino project for beginners to get into. It uses an ultrasonic sensor, which is placed inside the bin, to detect the trash level.

All modules are well-known off-the-shelf parts so we won’t go into details this time. Getting started with the Maker Uno RP2040 board using the Arduino IDE As mentioned in the introduction, the Maker ...

The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

This project combines Arduino and Processing to create a radar-like visualization of distance measurements. The Arduino code reads data from an ultrasonic sensor and a servo motor, while the ...

The real-time PIR sensor in Proteus senses the motion of a particular area. As Proteus is the EDA, to show the motion, a TestPin is present on the sensor. I used the toggle pin here to indicate the ...

Using ultrasonic sensing and routines with your Amazon Echo allows it to do a lot of things. If you have smart bulbs, then you can program it to switch on your lights when you enter a room.
