“This project will describe how to make a simple digital voltmeter (DVM) using a PIC16F688 microcontroller. The range of this DVM is 0-20V, but you can easily increase or decrease the range of input voltage as your requirements after you understand the voltage scaling method described in this project.”

“This is an article from an electronics amateur, experienced in embedded design and programming. He has utilized the BPS-5-3 breadboard power stick, LC04A Logic Level Shifter and WIZnet Serial to Ethernet Gateway, to show a basic interface between WIZnet gateway, Graphic LCD, PIC microcontroller and the setup.”

“In this article, i will use the PIC 16F1937, a powerful microcontroller with a 16-channel capacitance module. I will only use the 4 of them, but the idea to expand it to all 16 channels is the same.”

“In this project we have used two types of different R.F Modules like 433Mhz and 315Mhz Interfaced to a Pic16f877a, HT640 for R.F Encoding and HT648 for R.F Decoding. We will use two sensors one for temperature sensing: LM35 and another one is a potentiometer. The two sensors have an output of analog signal and that analog signal is fed into to two adc channel of the pic16f877a.”

“Few month ago I wanted to try to write software for Microchip PIC16F883 microcontroller and I couldn’t find simple development board for it. And so I made my own.”

“A while ago I got my hands on some old split-flap displays from a train station. Yesterday I finished driver circuits for 8 of the segments. It was only just in time to also quickly implement a clock algorithm for an extraordinary clock to display the turn of the year. Don’t miss the movie at the end of this posting.”

“The analog output voltage from the sensor is measured through an ADC channel of the PIC16F1847 microcontroller. A voltage to current conversion equation will be derived and implemented in the firmware of the PIC microcontroller and the actual load current will be displayed on a character LCD.”

“The cube described on this page uses a 5 x 5 x 5 matrix of single colour LEDs. This is a good size to experiment with as the number of LEDs required at 125 keeps the cost down, doesn’t take too long to assemble and just fits onto a eurocard sized PCB. The power requirement is under 1 amp and the use of just one colour keeps both the hardware construction and control software fairly simple.”
