CD4511

CD4511 is a BCD to 7-segment latch decoder driver IC formed with CMOS logic and NPN bipolar transistor output devices on an immovable structure. This IC is used where we need to driving common-cathode displays like 7-segment display, low voltage fluorescent display, and incandescent display.

CMOS Clock

“Introduction I’ve recently become interested in clock projects, and it seemed appropriate to start by building the essential digital clock assembled from logic chips. Although clock projects exactly like this have been around for the best part of 50 …

Creating a Life Clock

“The idea I’ve been obsessed with optimising and tracking my time since university. I wanted to know exactly where I was spending my time, and how it’s possible that I seemingly could go through a whole week without …

Ultrasonic Sensor Based Water Level Indicator

“When I started learning electronics, a water level indicator was the first project I made using some transistors, leds and a copper wire completely dipped in the water tank. But due to obvious reasons, it got rusted. Then I made …

Single Digit Voltmeter with LM311

“I wanted to design a logic probe as a tutorial, but there were many good ones in the web so i have tried to design a single digit voltmeter. This circuit is a design, i am unable to test it …

Measurement Of RPM Of DC Motor Using Arduino And IR LED

“What is our requirement? Here we want to measure the rpm of DC motor. So we have to measure how many times a particular point on the rotor undergoes a full rotation within a minute. So we have to use …

DIY Bike Speedometer

“I just finished my latest project: A speedometer for my bike. It uses an attiny84 chip as its main processor and an 74ls47 chip as a driver for its 7-Segment Display (7SD from now on). If you have the parts …

Motorbike Gear Position With Seven Segment Display

“This is project involves decoding a number of inputs (in this case 7) to display as numerical values on a Seven Segment Display (SSD) using something called Binary Coded Decimal (BCD), a Diode Matrix and a micro-chip called a BCD4511 …

DIY Arduino based PHOTO BOOTH

“We have built this first version of our Photobooth for the wedding of friends, cause we noticed that it would cost almost the same to rent a even simpler one. We have tried to make it as cheap as possible …

7-Segment and 8x8 Matrix LED Controls

Sending information from the micro-controller to the user is extremely important to help in the interaction between the two. The use of 7 Segment LEDs is a common practice since they are simple to use devices that allow the sending …
