LPC824 NeoPixel IR Distance Sensor
Drive NeoPixels and a Sharp IR distance sensor with the ARM Cortex M0+ LPC824 MCU
by Kevin Townsend
This guide demonstrates how you can drive NeoPixels and a Sharp IR distance sensor using bare metal C, and the State Configurable Timer (SCT) on the inexpensive ARM Cortex M0+ LPC824 microcontroller.
Adafruit VL6180X Time of Flight Micro-LIDAR Distance Sensor Breakout
Bounce a mini laser off stuff!
by lady ada
The VL6180X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL6180X can detect the "time of flight", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the VL6180X is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.
Adafruit VL53L0X Time of Flight Micro-LIDAR Distance Sensor Breakout
Use the power of photons for good!

Light of Your Life Wedding Bouquet
Beautiful flowers that glow more brightly when your love is near
by Erin St Blaine
Your world gets brighter when she's nearby. Your wedding flowers should too. This bouquet and boutonniere are paired with RF radios and neopixels. The closer the two are together, the brighter the flowers glow. Show the whole world the way she makes you feel.
Quadcopter Spray Can Mod
for sanctioned UAV painting
by Becky Stern
Use some electronics and either parts from your local hardware store or 3D printer to make your quadcopter paint with a spray can!
Calibrating Sensors
Get peak performance from all your sensors.
by Bill Earl
Most modern sensors perform quite well right out-of-the box. But the sensor is only part of the measurement system. For best accuracy in critical applications, you will want to calibrate.
Magical Mistletoe
Step under the mistletoe and you'll get more than a kiss--the berries light up!
by Leslie Birch
This holiday shed some light on your relationship with glowing mistletoe. The magic comes from a motion sensor, Trinket and LED sequins. When motion under the mistletoe is sensed, the berries light up.
IR Breakbeam Sensors
Get going quickly with these simple IR breakbeam sensors
by lady ada
Infrared breakbeams are invisible to the human eye, so they make for great movement detection circuits, with fairly good precision
Capacitive Touch Holiday Light Control

PIR Motion Sensor
Pyroelectric ("Passive") InfraRed Sensors
by lady ada
PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. This guide will show you how they work, how to use them, and give you some project examples.
