TinyCAD is a program for drawing electrical circuit diagrams commonly known as schematic drawings. It supports standard and custom symbol libraries. It supports PCB layout programs with several netlist formats and can also produce SPICE simulation netlists. It is also often used to draw one-line diagrams, block diagrams, and presentation drawings. Synchronous Circuit Timer. A synchronous circuit is a digital circuit in which the changes in the state of memory elements, commonly flip-flops, are synchronized by a clock signal. Because of their availability and ease of use, the 555 astable circuit is the common source of clock signal in many synchronous circuits.

In this project, we are using to create various timer circuit like 1 min timer circuit, 5 min timer circuit, 10 min timer circuit, and 15 min timer circuit. Here, with the help of the 555 timer IC, we are eliminating the need of manually switching ON or OFF the device.
Also, 555 Timer is used to generate an oscillating pulse. Which means that the output pin3 of 555 Timer IC is in “OFF” condition for some time and again comes in “ON” condition after a pre-set time interval. We can use this oscillating behavior of 555 Timer IC to create the timer circuit of different time delays. To create the timer circuit for the desired time interval, simply change the value of the resistor R 1 or Capacitor C 1.
There are three 5K ohm resistors connected together internally. This produces a voltage divider network at Pin 8 and Pin 1. The two comparators produce an output voltage that depends upon the voltage difference at their input. The voltage difference is determined by the externally connected RC network. The output of both the comparators is connected to the input of flip-flop to produce either a “High” or “Low” logic output based on the states of Input.
The output from flip flop can be used to control a high current output switching stage to drive the connected load producing High or Low level at the output pin. It can be used in motor vehicles to control the wiper speed by setting a definite time for the wiper to be in action.
It can be used in devices to produce alarm after a certain time interval automatically. It can be used in lamp dimmer to glow the LED automatically after a certain time interval. It can be used in the circuit where you want to produce a cyclic operation. In air-cooler, there are pump waters to the mat continuously. We can use the timer circuit to Switch OFF the pump when mats are wet and to switch ON again when the mats get dry.
Related Post:Bottom Line. In the above discussion, we have designed the timer circuits of 1Minute, 5Minute, 10 Minute and 15 Minute time delay using 555 Timer IC. Timing devices are of great use in day to day life and are very easy to design.
We can rely on a 555 Timer IC for generating the time delays of 15-20 Minutes. We hope that you have got a good knowledge of 555 Timer IC and different timer circuits using the same. Now, you can easily design the different timer circuits of 1Minute,5 Minute,10 Minute and 15 Minute using 555 Timer IC with ease. Such types of timers may only be suitable for child’s plays because no constancy of timing can be achieved with such RC circuits.It would be an extremely vague to represent the timing characteristics of such circuit by ” T = 1.1.
R. C “.
As a matter of fact the non-precise and crude characteristics of Electrolytic capacitors of higher MF. Values do not allow those to be used in such applications faithfully. Drift in their capacities due to constant ageing, internal leakage factor, temperature, working voltage etc. Makes those non suitable for any precision application. Their result is expected within a broad spectrum of +/- 20%.
Of course their results could be utilized for non precise timings in 10 – 30 seconds range while using lower values of resistances. Also that, there is no compulsion for using a 555 ic, just a Darlington along with a Zener could be used with similar R C circuit for achieving the results – Rajiv Mohan.
