This software functions as a long period astable mutivibrator. The mark and space period can be set from 1 second up to a maximum 65535 seconds (18h12m15s). Using the internal 4Mhz RC oscillator delays with an accuracy of 99% or better can be achieved.... -
Multivibrators is two state devices which is used extensively in digital electronics. The bistable multivibrators or called filp-flop are the basic memory.... -
This Design Idea offers a solution to the challenge of turning devices on or off in the past. In Figure 1, IC2 is a 555-type timer (preferably CMOS) connected as a monostable one-shot multivibrator. The pushbutton switch, S1, triggers IC2. You can replace....

The easy way to clamp a signal to a given value is to use two zener diodes, connected back-to-back. This method has several disadvantages. The accuracy of the clamping depends on the tolerance of the zener diodes, and the clamping is not adjustable, except....

The 74L121 and 74L122 ICs pin out diagram works any any style 74xx121 or 74xx122 DIP chip, but the timing graphs are only valid for the TTL families indicated. The 74121 shown above provides a single Monostable Multivibrator function. While the 74122 shown.... -
The circuit in Figure 1 is a simple, low-cost voltage-to-time converter using the ubiquitous 555 timer chip. You can use the IC`s monostable multivibrator as a voltage-to-time converter by connecting the analog-voltage input to the charging resistor, R,....

Are you familiar with the basics and applications of the 555 timer IC Are you looking for a book that provides all these basics If so, CircuitsToday has started an online store from where you can buy books on 555 timer IC, which have been reviewed in detail..... -
In the 555 datasheet they have a pulse width modulation circuit similar to this with the only difference being that they have pin 5 labelled as `audio .... -
This circuit is a monostable multivibrator, or one-shot, made with a 555 timer chip. Click the logic input on the left (the "H"), and the output goes high for a short time, and then it goes low again. A timing interval starts when the trigger input ("tr") is.... -
Well i posted a similar circuit in another topic but a lot has changed in the design. So here is a brief story of what i am doing, actually i am in a project where i have to design a circuit which can be used to trigger solenoid valves for the airbags in the.... -
Description:The following circuit shows about Basic Monostable Multivibrator. This circuit based on the 555 Timer IC. Features: Pin 4 is the RESET, t=R1xC1, .... -
A monostable multivibrator (MMV) often called a one-shot multivibrator, is a pulse generator circuit in which the duration of the pulse is determined by the R-C network, connected externally to the 555 timer. In such a vibrator, one state of output is stable....

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 principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
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.....
