SHARP GP2Y0A41SKOF Infrared Distance Sensor (4-30cm)

INTRODUCTION

This Infrared Proximity Sensor made by Sharp (model: GP2Y0A41SKOF) has an analog output which varies from 3.1V (4cm) to 0.3V (30cm) with a supply voltage between 4.5 and 5.5V DC. This sensor is great for sensing objects up to 30 cm away. It has a Japanese Solderless Terminal (JST) Connector which is compatible with our JST accessories.

Project 2: Never Forget Your Keys: NFC Door Reminder with Arduino Leonardo

This project is essentially an NFC reader that you stick on your door. Every time you approach the door the circuit makes noise; the only way to stop the noise is to scan an NFC tag affixed to your keys against the reader. Thus, the noise means you won’t ever forget your keys again! Let’s dive in.
