Proximity Sensing with the VCNL4000 + Arduino

I’m not really sure why, but proximity sensors are some of my favorite things in the sensor world. Maybe because there are so many of them? Who knows. Whatever the reason, the VCNL4000 is another proximity sensor that caught my eye, so I picked one up from Sparkfun on this handy breakout board. The VCNL4000… Continue reading Proximity Sensing with the VCNL4000 + Arduino

Simple Temperature With Thermistor + Arduino

A Thermistor is a thermal-resistor. It’s just a simple device that changes it’s resistance based on temperature. If the LRD/Photoresistor is day of of arduino class. The thermistor should be day 1.01. (Can I do that?). If you need precise temperature readings, this is not the part for you. Check out the DS18B20, TMP102, or… Continue reading Simple Temperature With Thermistor + Arduino
