led protection
All optical transmitters will include circuitry designed to limit the current to a safe value that protects the LED during short-term incidents. Red, Red-Orange, and Amber Luxeon I LEDs have a peak current rating of approximately 550 mA. At this...
valentines day gift
This year for Valentine's Day, an electronic project was created for Caroline. Initially, an attempt was made to construct an animated LED heart using a joule thief circuit with a single AA battery; however, difficulties in creating a suitable air...
Bluetoothß„? Front-end Ic T7024 Design Guide
The HV9911DB2 is an LED driver designed to drive up to twenty 100mA LEDs in series from an input voltage range of 9 to 16V DC. This demonstration board utilizes Supertex's HV9911 integrated circuit (IC) in a boost converter topology....
led display circuit diagram
This page presents a replacement circuit for the LM3909 LED Flasher/Oscillator utilizing discrete components. The circuit functions similarly to the integrated LM3909 but features minor variations in the component values used. Although the LM3909 is still available, it tends to...
VU Meter 4
The circuit is connected in parallel with the output of the power amplifier and provides the signal level from the output. By adjusting resistance R1 in the input circuit, the power indication can be adapted according to the resistance of...
Power 220V LED Flashing
An AC mains operated single LED flasher circuit is designed using the widely used CMOS timer chip TLC555. The entire circuit is powered directly by the grid supply of 230VAC through a capacitive potential divider and associated components.
This LED flasher...
Knightrider lights for model cars circuit
This simple circuit drives six LEDs in a "Knightrider scanner mode." Power consumption primarily depends on the type of LEDs used, particularly when utilizing a 7555 (the CMOS version of the 555 timer).
The circuit is designed to create a visual...
knight Rider 2
This project describes a light effect that is similar to the one of the car in the TV series "Knight Rider."
The light effect project emulates the iconic scanning LED light sequence featured in the "Knight Rider" television series. The design...
10 led VU Meter using LM3915
The circuit diagram illustrates a straightforward circuit design featuring 10 LEDs. It employs a series of half-wave rectification using the precision IC2 TL071, along with a single LM3915 IC that regulates the LEDs, functioning as a VU meter indicator. The...
