This 6" x 18" clock needs 52 light sources. It may one day allow humans to know the time without glasses. For 25 years we searched for clocks big enough to be see without glasses. No large clock existed commercially so our only resort was to have clocks.... -
The clock, which is made from 25 CD4000 ICs, three 555/556 ICs and a handful of discrete components, includes an alarm and a way of setting the clock that until now I have only seen implemented using microcontrollers. All this makes for a rather involved.... -
This is a project I`ve done on behalf of a person on an internet forum. The requested operation is simple: Use an EasyDriver stepper motor driver and a 1. 8 deg/rotation stepper motor and make the motor turn one revolution per minute. This frees me up a bit.... -
Schematic diagram in hard copy relating to the compurter CSIRAC. Schematic diagram shows the detailed connections between all the components in a circuit. They are used to build the circuit and later for testing. For CSIRAC, the most common components were.... -
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. Propeller clocks were to my knowledge first.... -
One of the many random devices I`ve found in my sometimes frightening basement was an HP frequency counter. The thing is built like a rock, still works perfectly and the manual contains full parts list, a complete circuit diagram and a description of the.... -
This is a programmable alarm timer ambit that uses alone LEDs to announce hours and minutes. 12 LEDs can be abiding in a amphitheater to represent the 12 hours of a alarm face and an added 12 LEDs can be abiding in an alien amphitheater to announce 5 minute.... -
The amount 1. is a block diagram for agenda alarm and agenda thermometer. It consists of 1 temperature sensor, RTC, Microcontroller(PIC), about-face annals, 7-segment and key board. The about-face annals use for aggrandize I/O of CPU becuase it has 13 I/O.... -

The count advances as the clock input becomes high (on the rising-edge). Each output Q0-Q9 goes high in turn as counting advances. For some functions (such as flash sequences) outputs may be combined using diodes. The reset input should be low (0V) for.... -
This is digital clock schematic diagram. This circuit is quite complex and quite difficult for a newbie because this circuit uses IC with some a complicated connections. The voltages that supplied to the circuit are divided in two lines. The voltage +5VA.... -
The Arduino displays the time and date on a LCD (optional) and in the Arduino IDE serial monitor window. A PCF8563 real time clock (RTC) IC is used to generate the time and date. The time and date can be set using the Arduino serial monitor window. An.... -
A series of digital clocks, all with LED outputs, were created for the Electronics in Schools Strategy (EiSS) and used in several of the courses run on behalf of SETPOINT (now STEMPOINT) Devon & Cornwall for secondary school teachers in the south west. The.... -
The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in the world accurate time and date. NTP is a simple UDP based protocol and can be implemented in a Microcontroller. So far we have only implemented UDP and TCP.... -

The WWVB signal is broadcast as a 60 kHz carrier that is AM modulated with a time code frame that is updated once per minute. The data rate is one bit per second. Along with time code information, the data frame also contains synchronization bits, calendar.... -
This is the first electronic circuit I designed from scratch, my first time programming a MCU, the first time I wrote an application in assembly language and my second homemade PCB. Usually people starts building very simple things and they increase the.... -
Digital clock project based on the PIC16C54 microcontroller can be designed using the following circuit diagram. This digital clock electronic project based on the PIC16C54 is a simple time-of-day clock incorporating four seven-segment LED displays and three.... -
Clock timer uses a PIC16F628 microcontroller to display 3 and 1/2 digit time and control an external load. The clock includes a calendar with leap year and optional daylight savings adjustments. The timer output can be set from 1 to 59 minutes and manually.... -
This project describes a digital clock with alarm function. It uses a PIC16F877 microcontroller to generate an accurate 1 sec delay with Timer0 using Roman`s zero error method. The time is displayed in large size font on a 4G—20 character LCD that uses.... -
You have mentioned 89S51/52.But in the picture I see 89C51. Which one do I use for the given .hex file(without the need to change the .hex file)?2.... -
Most of the LCD issues are due to Delay routines only. First try to interface LCD properly then try for your digital clock. Step by step approach is important. You may refer to LCD tutorial which is in tutorial section. code is ok i check it on Proteus it is.... -
For those are not into electronics, you must know that an oscilloscope has basically only one timebase to move the spot horizontally from left to right with the same intensity. The vertical deviation is function to the input voltage. You understand....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
