Build an LED Restroom Sign for your Wedding or Conference Hall

How to build an LED Toilet Pointer- a DIY project 

'Stop the bathroom blunder!' Ever wandered around a huge venue like a wedding hall or conference center, desperately searching for the restroom? The panic of a full bladder in an unfamiliar place is real. We're going to build a device that saves you from that stress and embarrassment.

This simple DIY project will save you from that awkward, frantic hunt.

Illuminate your path to relief. Imagine a bright LED arrow pointing the way to the nearest toilet. It's not just a cool gadget; it's a beacon of hope for anyone lost in a new, unfamiliar building.

Ever get lost looking for the restroom in a huge, unfamiliar venue? We've all been there—wandering through a massive conference hall or a sprawling wedding venue, desperately searching for a sign. This simple, DIY gadget will solve that problem for you and your guests forever.

Want a project that's both super useful and visually appealing? We're building a practical, elegant LED sign that is perfect for any large space, from a bustling wedding hall to a quiet gallery. It's a simple build with a huge impact.

Ever notice how hard it is to find the restroom in the dark or in a crowded room? This project solves a real-world problem with a simple, clever solution. Discover how to create a clear and visible guide that helps everyone find their way.

Ready to build a smart home gadget that you'll actually use? This LED pointer isn't just for fun; it's a genuinely useful tool that improves convenience and accessibility for everyone, everywhere. Let's get started.

Know your circuit 

An LED toilet pointer circuit schematic is given here. It is a simple circuit built around the CMOS IC 4049.  

Know your design

The circuit uses a 16-pin IC 4049, which has 6 inverters N1 to N6. See the circuit schematic of how these inverters are connected with 8 LEDs. The 6 inverter circuits sequentially operate and illuminate the corresponding LEDs connected with it. Inverters N6, N2, N3, N4, N5 and then N1 work sequentially in this order and light the LEDs D1 to D8.  Sequential time delays for the inverters are achieved through an RC network in the circuit. Sequential glowing of the LEDs one after another from D1 to D8 in the shape of an arrow attracts the observer's sight. The circuit draws a current of just 50mA for operation. As such, a PP3 9V    battery works perfectly. No external power supply is necessary, hence it works during power failures too.   

Know your assembling

The 16-pin IC 4049 pin diagram is given here for ease of assembly. 

Also, take the help of the picture given below to connect each LED to the corresponding inverters. One Red LED D1with a load resistor R1 is connected to the inverter N6. 

Pin 1 is connected to the +ve power supply. Pin 8 is connected to earth, i.e., -ve power supply. 

The LEDs are arranged in the shape of an arrow. An illustrative picture is given here.  

The circuit can be assembled on any general-purpose PCB or even a solderless breadboard.  Use a 16 Pin DIL socket to insert the CMOS IC 4049.
