He built an RGB LED circuit controlled by a PIC12F683 microcontroller, which shines into a hand-etched plexi-glass panel. The LED color is controlled using PWM, as you would expect.

By combining the RL78/G1D BLE microcontroller and the RGB LED driver circuit, the LED lighting system can be controlled remotely with precision. The Bluetooth connectivity ensures a low-energy, stable ...

LED scrolling display circuit and working. The circuit diagram is divided here into two parts. The first part has a power supply and controller circuit as shown in Fig. 3. The display unit is in the ...

I have drawn the characteristics of a RGB LED for you. Depending on which microcontroller you use, the red LED would not last long in your circuit at 3.3 volts without a resistor. Even more ...

The image below shows the RGB LED module with 8 WS2812B LEDs in series. Each of these LEDs can be controlled individually using just one wire. The data in of the first LED is connected to the ...

This project focuses on designing a voice-controlled automation system for IoT devices, enabling users to control an LED light wirelessly through simple voice commands. Introduction: In the era of IoT ...

This paper describes one solution of LED based luminaire control. The device is powered by 230V/50Hz AC network using 20W flyback regulator with optimized PFC, which is an advantage over common CLF ...

The internal circuit diagram of an 8x8 led matrix looks like this. As you can see that the led matrix has 8 row pins and 8 column pins to control specific leds. When these row-column pins are given ...
