- .. board): The picture shows a full-volume 5000Hz sine wave generated by a PC. If we were to feed this signal directly to the PIC we would only have a very small range of input voltage (0-0.5V) and also we would only be able to sample the ...18-01-2011
- Part 1. Schematic Calibration and Testing Once everything is assembled take following steps to calibrate the system, Remove IC1, IC2, IC3 and IC4 from the IC bases. Apply 18V ( to 22V Max.) DC source to the power connector (J3). Check the voltage ...08-01-2011
- Introduction In this project we design low cost high performance programmable home security system using few LDR's as an input sensors. When above sensor(s) get triggered system may dial the user specified phone number (using build-in DTMF ...04-01-2011
- The Button Code is a system that allows a single button to act as a keypad. The user enters a 4 digit code into the system using button taps. The button can be placed where the public can access it since like a keypad there are many combinations to ...17-11-2010

- .. of ADC is set to 1V with potentiometer connected to Vref+ pin of PIC32. Voltage of the audio signal could be negative but PIC’s ADC accepts only positive voltages. That’s why another pot is used to add 0.5V DC to audio signal. ...26-10-2010
- Recently I’ve working with the little but smart PIC18F14K50 (or your low voltage version, PIC18LF14K50 ). These chips are cheap (about $2,5 at Mouser) and have low pin count, but very impressive specs: USB V2.0 (low and high speed); NanoWatt ...23-10-2010
