For patients to receive good care, doctors must be present. To administer medication or provide treatment, he can’t be everywhere at once. If we regularly examine our health, we may be able to ...

An infrared sensor based prototype of self-adaptive traffic signal control system has been developed in this paper. An autonomous traffic signal system can be an effective measure to alleviate ...

If the sensor detects an object (i.e., the output is HIGH), the Arduino sends a signal to turn the LED on and then off, causing it to blink. LED Indicator: The LED blinks in response to the sensor's ...

int IRSensor = 8; // connect ir sensor to arduino pin 2 int LED = 11; // connect Led to arduino pin 13 ...

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 ...

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, ...
