Working Principle The IR sensor emits infrared light from an LED. When an object comes into range, the emitted light reflects back to the sensor’s receiver module. Based on the intensity of the ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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 ...

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 ...

The sensor operates at 5V for Arduino and 3.3V for Raspberry Pi, ensuring seamless integration with these popular microcontroller and microcomputer platforms.

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 ...
