I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I. ... to ~38kHz signal yielded by D9 of the ...

You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. In this project bot follow the ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

The robot has been programmed to move in the direction where the rays have not been reflected, in other words, follow a black line on a white surface. About A line follower robot using Arduino Uno, ...

“Muxall open source Infrared Detector (IRD) for reflective sensing, light curtains, and fast proximity applications. Works with Arduino (5V) and Raspberry Pi (3.3V) TTL.” ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now ...

Compare it to some giant old UNO ... for Arduino fans. [Stefan] beefed up the robot with a BNO055 module to determine orientation, an APDS-9930 proximity sensor, as well as four CNY70 IR ...

So this inspired us to use GSM module for this project since the telecom network is widely spread within rural & urban area of the India. This system is used to monitor physical parameter like heart ...
