Sensirion's SHT1x and SHT7x series of humidity sensors interfaced to PIC Microcontroller

Sensirion's SHT series of humidity sensors integrate sensor elements with all the required signal processing circuits on chip, and provide fully calibrated digital outputs for relative humidity and temperature measurements. This tutorial explains how you can interface a SHT1x/7x sensor to a PIC microcontroller to measure ambient temperature and relative humidity. The tutorial described in full detail about the sensors, their specifications and interface, and the implementation of communication protocol using mikroC compiler.

Fundamentals of LED dot matrix display

LED dot matrices are very popular means of displaying information as it allows both static and animated text and images. This tutorial describes the basic architecture of a LED dot matrix display and its interfacing with a microcontroller (PIC18F2550) to display static characters and special symbols.
