Chromation Systems RGB LED Tube Light
Posted on: 05 Oct 2017
Built utilizing a 24 Channel High Current USB LED Controller to control 12 volt RGB LED Light Strip, in 8 separate groups. Each group has individual 8-bit PWM which can create over 16 million colors. And is driven at full current for maximum color saturation and accuracy. Using the ColorMotion Compatible Firmware, various colors patterns and effects can be created […]
Incredible DIY iPhone Macro
Posted on: 05 Oct 2017
After taking apart dozens of disposable cameras over the years, I found myself with a lot of lenses of varying sizes and nothing to use them for… until now! By making a simple carriage that would hold the lens and attach to my iPhone via rubber band, I was able to make a virtually free […]
Compost Sensor
Posted on: 05 Oct 2017
Introduction This is a tutorial on building a Compost Temperature monitoring system. It details how to build a web connected wireless sensor network and shows one possible way it could be constructed. A Medium level of knowledge and skills are required. Basic knowledge of soldering and breadboarding will be very useful. I will assume that […]
Interfacing DS1307 to PIC Microcontroller with C code and Circuit Diagram
Posted on: 05 Oct 2017
Interfacing DS1307 to PIC Microcontroller with C code and Circuit Diagram This tutorial explains how to interface the DS1307 Real Time Clock (RTC) with a PIC16F877 microcontroller. The project is compiled using the CCS compiler and simulated in Proteus. The DS1307 communicates with the PIC microcontroller through the I2C protocol, which is a two-wire, serial, […]
Twin triac AC switches

How to use an RGB LED – Arduino Tutorial
Posted on: 05 Oct 2017
An RGB LED has 4 pins, one for each color (Red, Green, Blue) and a common cathode. It has tree different color-emitting diodes that can be combined to create all sorts of color! Any color is possible depending on how bright each diode is. In this tutorial you will learn how to use an RGB […]
Dual 4-digit seven segment LED display with SPI interface using PIC12F
Posted on: 05 Oct 2017
This project is an extension of my previous MAX7219 based SPI seven segment LED display module. The new display features eight 7-segment displays arranged in two rows of four digits. The on-board MAX7219 driver enables you to easily add eight 7-segment LED displays to your project using only 3 I/O pins of microcontroller. The major […]
