Time Lapse Circuit Diagram

Introduction

Time Lapse Circuit Diagram can be a great tool for those looking to see how their electronic projects will be wired up. It simplifies the process of connecting each component together, allowing you to see the project in greater detail and making it easier to troubleshoot problems. Additionally, these diagrams help with understanding the logic of a particular design, as they show which components have to interact with each other in order to work as intended. Given their comprehensive nature, these diagrams are an invaluable resource for anyone working in electronics, from hobbyists to professionals.

Time intervals play an important role in electronics and more particularly in test and measurement technology. Normally, a digital circuit is used in which an oscillator provides good resolution and reproducibility. The present circuit is no exception: it consists of a retrig gerable monostable multivibrator (MMV), a Clear circuit, a decimal counter and a BCD-to-decimal counter (BCD-binary coded digit). The gate at its output enables it to be operated from an external source. The input of the MMV is linked to the TTL output of a clock generator, which may be an oscillator or a switch (for inputting single pulses).

The MMV is triggered at each leading edge of the clock and generates a pulse of about 7 ms, which is long enough to allow any switch bounce to be eliminated. The pulse width may be altered by changing the values of R1‚ and C1. The trailing edge of the pulse increases the counter state by one.

When the counter state is zero, pin 1 of IC3 (7442) is low and all other outputs are high. Diode D1‚ then lights. Output gate IC4 is disabled, irrespective of the levels at its other inputs.

Incoming pulses raise the decoder state and make the outputs of IC3 high sequentially. Diode D₁goes out and the counter is enabled.



The desired time interval is set with one (and only one) of the DIP switches in S2. There is then a low level across the relevant switch, which is applied to pin 2 of the output gate, diode D2 and reset input pin 3 of IC1 (74123). The LED lights and the MMV is disabled, so that all further input pulses are ignored. The output of IC4 (7410) goes low, provided that pin 13 is high. This pin may be used for external control or as window input. If these are not used, the pin should be held high permanently. In this state, the circuit is stable and may be restarted with a reset.

The current drawn by the circuit depends largely on the type of ICs used. With TTL circuits, it is about 50 mA, whereas if LS chips are used, it is only about 10 mA. If CMOS ICs (either HC or HCT) are used, the current is determined almost exclusively by that through the LEDs. Note that CMOS devices need additional pull-up resistors: 4.7 ks to the +ve supply line from pins 2, 3 and 6 of IC2 (7490) and pin 2 of IC₁. These resistors prevent undefined levels and consequent errors.

Conclusion

Time lapse circuits are incredibly useful and popular tools for capturing moments that we may not be able to relive again. They are great for capturing the stunning sunrises, sunsets or even just a simple progression of stages or activities throughout the day. With a wide variety of available settings to choose from, they can easily be customized to our specific needs while still being incredibly cost effective. Whether you want to capture moments at home or out in nature, time lapse circuits provide you with an easy way to capture those memories without having to worry about manually controlling your camera every second.
