E522.48 – 16 CHANNEL AUTOMOTIVE LED DRIVER WITH BUS INTERFACE

The E522.48 is a multi-channel PWM driver for e.g. light application. It provides 16 current sinks with integrated 10bit PWM generator for each channel. Each of the drivers can digitally be configured to drive up to 100mA with a selectable slew rate. The device supports I²C bus controlled operation to enable fast light animation sequences. For failsafe conditions the […]

A 12hr/24hr LED Clock with display control using PIC16F628A microcontroller

This LED clock may not be the easiest to build but surely it is the one with fewer parts that you can find, for that reason I call it “The ANP LED Clock”. (ANP stands for Almost No Parts.) Using the micro controller PIC 16F84A or the 16F628 (same pinout), this clock have more and

How to getting started with microcontrollers projects using PIC12F629 microcontroller

Microcontrollers are, basically, a computer in a single chip. It contains memory, processor, I/O ports (I/O = Input/Output) and other periphericals. Can you believe a single chip does contain RAM, ROM, CPU, I/O Ports, timers and other gadgets? It only needs a keyboard and display to be a working computer… …I almost forgot; It also

7-Segment ASCII character Set A 127-character ASCII table for 7-segment LED or LCD displays using PIC16C84

I started to develop what I call my “next generation of microcontroller projects” (I have to find a name for that), so I needed a character set fully compatible with ASCII using only 7 segment displays. When I started to determine how many characters and which ones I will use, I thought only 64 characters

SmartCube DOLORS

Introduction DOLORS is a smart lamp that, paired with a Raspberry Pi, is capable of showing live weather information upon request, such as the temperature and sky condition. Additionally, it provides dynamic animation modes with vibrant colors and computer vision features. The main reason for building the SmartCube DOLORS was to have an easily accessible

LED Binary Clock using PIC16F628A microcontroller

LED Binary Clock This is the second revision of my PIC based LED binary clock. The original version was the first PIC project I attempted, it used a PIC16F84A to do both the timekeeping and control the display matrix, unfortunately it didn’t keep good enough time and gained about a minute every week. This second

LED Amusement Park

Overview Our project consists of a 2m DotStar LED strip with 120 individually addressable LEDs and seven accelerometers with the Big Board to depict three different rides that are typically found in an amusement park: the roller coaster, the drop tower, and the bouncer. We implement 1D kinematic equations iteratively to approximate the real-world physics
