Dancing LED's circuit
Here is a simple circuit which can be used for decoration purposes or as an indicator. Flashing or dancing speed of LEDs can be adjusted and various dancing patterns of lights can be formed. The circuit consists of two astable...
The power indicator circuit
The ACER PM02 MP4 machine features a voltage status indicator circuit. When power is supplied, a red LED illuminates, indicating that the device is powered on. Upon entering operational mode, a green LED lights up.
The voltage status indicator circuit serves...
Halogen Lamp Dimmer With Soft Start
Most dimmers utilize pulse width modulation (PWM) to regulate the amount of power supplied to the lamp. Those that are packaged with a switch faceplate...
Dimmers that employ pulse width modulation (PWM) function by rapidly turning the power supplied to the...
2 LED Flasher
This is a 2 LED flashing circuit. It is based on an analog flip flop circuit. This particular circuit was calculated to use blue or white 3V LED with a 12V power supply. If you are using red green or...
Led sequencer/scanner
Yes, both of those transistor types will be suitable. Is the "sn9304" a 2N3904? That's a common type. You're going to have four LEDs on at a ...
The context indicates the use of transistors, specifically the 2N3904 or potentially a...
Led bar-graph driver
The circuit utilizes CA3290 BiMOS dual voltage comparators. The non-inverting inputs of A1 and A2 are connected to a voltage divider reference. The input signal is applied to the inverting inputs. LEDs are activated when the input voltage reaches the...
Propeller Clock Mechanically Scanned LED Clock
A motor spins the "propeller", and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion, but it works nicely.
The...
LED Chaser
I don't know why, but people like blinking lights. You see LED chasers everywhere, in TV shows (Knight Rider), movies, and store windows. This schematic is my version of a simple 10 LED chaser. There is no 555 timer used...
Construction LED circuit diagram CD4017 CD4011
The construction LED circuit illustrated in the figure requires manual power. Once powered, the light will blink to alert individuals to pay attention to safety.
The circuit is designed to enhance safety awareness in construction environments by utilizing a blinking LED...
