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 simple **dark sensor** project that is connected to a relay which u can connect to a domestic light or fan etc. thedevice make sure that when there is light, the relay will be switched OFF and when it's in the dark, therealy is turned ON.
ATtiny85 IR remote LED controller - mainly for ambient light behind a TV
Single colour LED
On first power up
Press PROG button to enter program mode
Programming can be over written once the PROG button is pressed
Press ON/OFF assigned button
LED fades in to set brightness value
Default to 50%

# Auto light
Attiny10 & APDS-9930 based automatic light/switch
This project utilizes small ATtiny10 mcu to work with APDS-9930 ambient light (AL) and proximity I2C sensor.
This is used for automatic "smart" light in a drawer. Once the drawer are open the APDS-9930 will notice proximity change
and trigger a pres...
As title says, 2 very simple PCBs with schematics
schottky diode and capacitor (ceramic / electrolytic doesn't matter) is part of smoothing and can be skipped for standard LED's, but it's needed e.g for self changing color ones
This project is Auto Watering, light control for indoor plants with 328PU or Arduino. The auto water part is working with the sensors in water reservoir. Adding light control is on its way.
Code is at:
Uses 328PU to turn off light or turn on as needed, Using much software. But it has micro wave detection, pir detection, audio detection, and light detection.
It is a very simple touch light, the circuit base on the Touch Screen Controller ICs RH6616, the datasheet has the design references
