This idea was born when i saw this project years ago: https://hackaday.io/project/170961-resistor-color-code-clock-v10 NOTE: There is a bug showing resistor values under 100 since gold nor silver can be displayed. AND the multiplier seems to be...
Today, i rewrite a code of ambient light of arduino module applied FastLED library carefully. Why? there are 3 important thing, 1) the legacy code of adalight is based on SPI that is used by a RF module too. I think move pin in code of adalight from...
This time I will show you how to make a sensitive Pulse Induction metal detector which is based on ARM STM32 microcontroller, which has significantly better features than Arduino and is also cheaper. It can detect metal coih at distance of 30cm,...
I made many projects regarding Audio amplifiers and preamplifiers but this tutorial is for the visual music experience. I am going to make a music reactive neopixel based LED strip. The LEDs will glow according to the change in beat and the color is...
#include #ifdef __AVR__ #include #endif // Which pin on the Arduino is connected to the NeoPixels? // On a Trinket or Gemma we suggest changing this to 1 #define PIN 6 // How many NeoPixels are attached to the Arduino? #define NUMPIXELS 48 // How much...
Controlling the WS2812 with STM8 eForth was something I've had on my to-do list for a long time. The lore of W2812 timing is already long and twisted, and any new implementation, it seems, has to add a bit to it :-) Mine is the following: ...
Wheel of The Year On 16 segment Display The wheel of the year is divided in 8 intervals, and the corresponding segment is lit whenever the current day is inside the interval. In the picture below, the segment will be lit from February 1st until March...
The protocol seems similar to the WS2812 LEDs, but is different enough that I feel it is worth sharing. I don't know the actual IC or part that is being used. It looks like a standard 5mm led with a flat face similar. It is very similar in appearance...
I often get these questions :How many LED can the WizYasep drive ?The answer is : a lot !The W5300 network chip has a 128KB FIFO, that's roughly 40KLED. Is that enough ?Actually I have reduced the receive FIFO depth to 56KB, or about 19K LED. My largest...
Introduction The current time is indicated by the position of the light. The lights are divided into three groups, respectively hours, ten, a fraction, read also more consistent with the habit, several dozens of minutes. The 12-hour system is adopted...
