The circuit was designed sensitive enough to trigger and activate the alarm upon sensing wetness, moisture or dampness on its probes. 555 Timer – an 8-pin electronic device used in several mixtures of ...

This is a simple LED Cube circuit designed using 555 timer. It can be very useful for home decoration purpose and home lighting systems. Many LED Cube circuits are available in the markets which are ...

One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
