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 ended up using a microcontroller and a piece ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

This repository contains documentation and code for a simulated Arduino lock system on Tinkercad. The system employs a servo motor controlled by an IR remote, with status indicators provided by LEDs ...

TCS3200 Color Sensor Working. The TCS3200 color sensor is used to sense a wide range of colors. We previously interfaced TCS3200 color sensor with Arduino and Raspberry pi, and also built some useful ...

so tinkercad has circuit designand arduno now, a real arduino is $20, IDE is free, fritzing is free and does all the exact same layout stuff locally, you save your files and keep them forever.
