Rotating LED Marquee Hat circuit
Here is the schematic for the circuit. Solder all the components onto a perfboard. The drawings may not be very clear. Essentially, the 555 timer generates a pulse.
The circuit utilizes a 555 timer IC configured in astable mode, which allows...
72 led clock
The circuit utilizes 60 individual LEDs to represent the minutes of a clock and 12 LEDs to indicate the hours. The power supply and timing circuitry are consistent with those outlined in the previous 28 LED clock circuit. The minutes...
Put That Light Out
If the light in a seldom-used room, such as a loft, is forgotten and left on, it can remain illuminated for extended periods, leading to significant electricity costs. To address this issue, electronics enthusiasts can design a simple circuit to...
Mains operated LED night lamp
A simple and effective LED-based night lamp circuit is designed to operate directly from the 230V mains supply. The circuit utilizes a total of 24 white LEDs, producing an output of approximately 15W. Current limiting is achieved through resistor R1...
28 LED Clock Timer circuit
This is a programmable clock timer circuit that utilizes individual LEDs to display hours and minutes. Twelve LEDs can be arranged in a circular pattern to represent the 12 hours on a clock face, while an additional 12 LEDs can...
Led indicates logic states
The CSL310L is a dual-color LED that incorporates a red LED and a green LED arranged back to back within a single housing. This LED can emit either red or green light depending on the polarity of the applied voltage....
LED torch using MAX660
This is a simple LED torch circuit based on the MAX660 integrated circuit from MAXIM semiconductors. The MAX660 is a CMOS monolithic voltage converter IC capable of driving three bright white LEDs connected in parallel to output pin 8. The...
LED Counter with IC 4017
The circuit presented this month is a basic configuration of the very versatile 4017 IC Chip. In the most common use of the IC, it will turn on 10 separate outputs sequentially. Typically, the circuit is used to turn on...
72 LED Clock
In the circuit below, 60 individual LEDs indicate the minutes of a clock, while 12 LEDs represent the hours. The power supply and timing circuitry are similar to those described in the previous 28 LED clock circuit. The minute section...
