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...
OK, big turnout as always when we have our Adafruit friends stop by! I'm Dan, I'll be modding today as we welcome PT, Limor, Scott, Dan and Jeff from Adafruit to talk about both the ESP32-S2 and the new RP2040. Welcome Adafruit people! pt12:00 PMhi...
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...
Having decided on serial communications for the blocks, I now need to devise a protocol so the blocks can communicate with each other and the master controller. What follows is some of the reasoning I used in devising the protocol I ended up using....
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: ...
Intro We had the combined experience of teaching with Arduino for some 15 years among the whole team, but all of us felt frustrated in a way or other by the way hardware was not really connected with the learning journey a beginner would face. Some time...
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...
Using the HaptiVision Belt as base we tried out if we can use it also as Display for playing games on it. Of course, with 16*8 pixel that's not high resolution, but we thought that at least games like Pong might work. Adaption was rather easy: Using...
