The data logger consists of a simple op-amp amplifier circuit that amplifies the signal and sends it to be digitized by a PIC16F688 microcontroller, serialized, and sent to the computer’s serial port via a MAX232 serial driver: I guess you are already wondering about some of the unusual arrangmenents in the analog part in the …
This post provides the external interrupt code for PIC12F675 microcontroller (e-g when you need to control servo motor which has position encoder, with your PIC microcontroller). As we know, PIC12F675 microcontroller has one GP2/INT pin, which can be used to service external interrupts. This code is written in C language using MPLAB with HI-TECH C compiler. You …

The goal of the electrical design was to streamline an automatic shift control while keeping manual user input in a fast, user-friendly way. The electrical design was driven by the complexity required by the mechanical system. The system takes in rider input in the form of a throttle position sensor, shift pushbuttons, and mode selector. …
Our circuit commercially available 4-color carbon resistor color code itself accounts. As our circuit structure is quite simple . PIC16F88 as a material for Nokia 3310 keypad and LCD 4 × 3 consists of a few simple elements . Application to the study, the 12 keys on the keypad each respectively black, brown, red, orange, …

Project Summary This is a mobile phone sniffer circuit that can detect the signals being used in the GSM (Global System for Mobile Communication) band at about 900 MHz. Since the signals are digitally encoded, it can detect only the signal activity, not the speech or the message contents. A headphone is used to hear …
This is a project for viewing the frequency spectrum of input signal using dsPIC. The hardware uses the following: – 1. dsPIC30F4011. 2. Opamp (any one, like LM358, TL084). 3. Power supply. Software includes the following: – 1. FFT library code from Microchip 2. Graphic LCD driver code (for line, pixel plot etc). Graphic LCD …
The PIC has a white arrow in the transistor and the clock is a little to the right. Pull-down resistor Tact switches are in line with the lower back.
