Objective: To build a system where an LED blinks whenever the IR sensor detects an object within its proximity range. This can be used in various applications, such as a simple object detection system ...

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, ...

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

LEDs on the Arduino can be programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). The two companies say that the hardware provides ...

Works with Arduino (5V) and Raspberry Pi (3.3V) TTL.” The IR Detector proximity sensor is not just limited to the applications mentioned above.

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 ...
