In this post I will show how to construct a few fireworks ignition circuits which can safely ignite them via IR remote and timer. We have proposed three firecracker igniter circuit designs using ordinary components which we will be exploring them in detail. Before we jump in to the circuit details, we have a word […]

Arduino 2-Step Programmable Timer Circuit
In this article I have explained how to make a simple 2-step Arduino programmable timer circuit, which can be used to switch an electrical load ON/OFF with independently adjustable ON and OFF timings. For example if you want a light to remain ON for 24 hours and OFF for 2 hours, you can simply do […]
Simple Digital Timer Circuit with 2 Digit Display
This simple digital timer circuit can be used to obtain timing output through selectable ranges, which can be set from 0 to 99 second, with 1 second interval, 0 to 990 seconds with 10 second interval, and 0 to 99 minutes with 1 minute interval. All these timing outputs can be visualized and tracked through […]
Simple Kitchen Timer Circuit – Egg Timer
A kitchen timer is a useful gadget which produces an alarm sound after a predetermined delay, as set by the user for specific time based food recipes that must be cooked only for a certain amount of time for best results. Written By: Suneeta Dixit One example is boiled eggs which may be either hard […]
10 Best Timer Circuit Diagrams using IC 555
The circuits I have explained here are 10 best small timer circuits using the versatile chip IC 555, which generates predetermined time intervals in response to momentary input triggers. The time intervals can be used for keeping a relay controlled load ON or activated for the desired amount of time and an automatic switch OFF […]
LCD 220V Mains Timer Circuit – Plug and Play Timer
In this post we are going to make an LCD 220 V mains operated timer using Arduino whose countdown time can be witnessed via 16 x 2 LCD display. Introduction The proposed LCD timer circuit is general purpose timer with display and few buttons for setting the time. Once the time is set output goes […]
