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...
Water detector with 4 level stages. Each stage makes the 555 timer to give a supply period for the buzzer. The active buzzer transmits sound with a pause period between 0.5-3 seconds, depending on the level detected.
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.
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...
**555 timer based PWM LED dimmer**
This project uses PWM to turn on and off a LED (or a strip of them) really fast and changes the duty cycle (Fig.1) so that the human brain perceive it as the dimming of the LED(s). This means that the MOSFET doesn’t have to drop large amount of voltage, this makes the device very energy efficient.
Simple module for creating your own led lamp. You can use RGB strip, WS2812b, one-color strip or others.
