By Arduino nano, control RGB5050 light colorful scroll.
From S1 to S4 was then performed, four buttons to control the beam of the rolling way, and switch to a different jumper mode, can display different colors of lig...
This electronic system is used in staircases or some other places where it is needed to have an automatic light switching controller. It's a device which turns on the light only when there is dark around and the switch is pressed. It will be turned off after the high state on the output of 555 has been over, according to the formula: t=1,1R2*C5. If you want to control some LED eg. COB instead of s...
This is a battery capacity indicator for 3.7V lithium ion batteries, using a bi-color LED (red-green) common cathode.
When the battery is from 100% to 50%, the LED stays green. When the capacity is from 50% to 20%, both LEDs turn on so it shows as yellow. When battery drops below 20% the green LED turns off leaving the red LED turned on.
It uses a schmitt trigger for both LEDs to prevent bou...
A dual microcontroller board for controlling "Neopixel" LEDs, with one micro dedicated to driving the LEDs while the other micro is busy reading push buttons, polling rotary encoders, reading IR remote signals etc etc.
The microcontrollers -two atmega328s -communicate with one another over their I2C bus. The very short wire run negates the need for the usual pull up resistors on the bus.
NeoPixel led strip controller, designed especially for led suits. It can:
- display animation - sequences of frames at regular (given) interval,
- switch animations on MIDI event - note on/off, velocity used for brightness adjust,
- MIDI over UDP over WiFi (UDP broadcast so far, but i'm working on multicast),
- use regular SD card to storage animations.
[These guys use them] for...
This project was made as a challenge to see how small I can go with conventional soldering techniques, this uses an Attiny85 with a QFN-20 package.
Este es un proyecto para ver que tan pequeño podía diseñar un circuito y culminarlo con soldadura convencional. Usa un Attiny85 con empaque QFN-20.
