This instructable covers the assembly and use of a Tiny Wearable LED kit. The kit is useable immediately but is desigend to be hackable and can be reprogrammed to your liking using an ISP p... Read more
High-power LEDs over 1W are now quite inexpensive. I’m sure many of you are incorporating LEDs as light sources in your projects. However I realize that the finding and configuring the... Read more
This week is all about analog inputs for the arduino. I’ll show you how you can use a voltage divider circuit (see episode 3) and a variable resistor to make an analog sensor. We’ll also use... Read more
This ones quite simple, just mix/ crossfade 3 separate LEDs using Phase Width Modulation (PWM) and Arduino. You will need 3 LEDs, I’m using a 5mm Red, Green and Blue so I can make the full l... Read more
This video explains how to use the 16 channel PWM controller TLC5940 The CODE: //Texas Instruments TLC 5940 with Arduino //www.kevindarrah.com #include <SPI.h>//Serial Peripheral Inter... Read more
Demonstrates the use of analog output (Pulse Width Modulation (PWM)) to fade an LED. PWM is a technique for getting an analog-like behavior from a digital output by switching it off and on v... Read more
This example shows how to read an analog input pin, map the result to a range from 0 to 255, and then use that result to set the pulsewidth modulation (PWM) of an output pin to dim or bright... Read more
