A simple but useful and stable circuit. In this state, it easily operates a 50W lamp without needing cooling. Of course, it got a little hot in my 100W experiments by connecting another one in parallel, but we can solve this problem by extending the length of the PCB a little and expanding the cooling…
This project is about the design and subsequent implementation of independently operating active cooling for LED components. Its basis is a 12V fan used for efficient heat removal. ATMega16 microcontroller was used as the control element. A circuit that effectively and appropriately meets the current cooling needs of the LED module using external sensors, increasing…
I made a visually different version of the 10 channel 100 Led Spectrum Analyzer circuit that I used in the 2.1 sound system. The filter quality of the Led Spectrum Analyzer is around 6, and the middle frequencies are 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz. J5 on the circuit changes…
The 10W LED Driver driver circuit is designed to operate a 10 watt LED matrix (3×3, 10-12V) with current limitation. It works in the Step-Down system. The ring core used for the 500uh coil is approximately 80 turns of winding with 0.55 mm diameter wire taken from the filter located on the output stage of…
Power LED driver Circuits made with TL494 pwm IC and MC34063 DC DC voltage converter ICs for LED Lighting. Actually there are a few more but I don’t mention them as there is no transformer information (files exist) First of all, I was interested in the LED driver circuit made with TL494 because it uses…
I will give information about how the HC-SR501 PIR motion sensor module works, HC-SR501 Features and its use with LDR. The HC-SR501 PIR sensor module can be used not only for security, but also for most automatically activated lighting systems, industrial automation, control areas. A few months ago, I used one of the batteries that…
The Strobe Led Lamp circuit has 16 effect modes selected with the button built on the PIC12F675 microcontroller. Since the selected mode is stored in the integrated eeprom, the selected mode remains in memory when the power is cut. The source is Picbasic Pro software. You can adjust the lighting times of the LEDs and…
I shared the ATmega88 microcontroller Led Heart circuit years ago. The LED Heart circuit that I have applied is controlled by the ATmega8 microcontroller. I made a lot of decoration on the PCB top floor and the PCB was made more useful for additional circuits. In the LED heart circuit, 22 ports of ATmega8 (ATmega8A-AU…
LM3916 Vu meter Circuit Indicator rna 10-point reading field made of LEDs. The diodes were scaled in dB, transmitting irn, from D4 to D13, respectively, the following weights: -20 dB, -10 dB, -7 dB, -5 dB, -3 dB, -1 dB, 0 dB, +1 dB, +2 dB, +3 dB. The LED indicator may work in line…
Amplifier for RGB strips The dynamically developing field of LED lighting means that a whole range of devices related to such applications is needed. One of them is the amplifier described here, which allows you to increase the current efficiency of the controller. Scheme of the RGB LED strips amplifier is shown in Figure 1.…
