Arduino Code for Speed Sensor In general, the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When ...

NTE30116 Tinted Blue 5mm Infrared LED Emitter (940nm) SM0038 Photo Module for PCM Remote Control System (38kHz) The principle of this setup is somewhat simple and self-explanatory. In this circuit, ...

Obstacle Avoidance Robot Using Ultrasonic and IR Sensors This project is an Arduino-based obstacle-avoiding robot that uses both ultrasonic and infrared (IR) sensors for navigation. The robot moves ...

Arduino Uno (or any compatible microcontroller) DC Motor with driver (e.g., L298N) IR Sensors (for ground and first floor detection) Seven-Segment Display (for showing the current floor) Push Button ...

Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide. Potentiometer tuning was a fiddly affair, but ...
