PIC12F675 Tutorial 7: A Servo controller driving a standard servo motor using serial port command

This servo controller generates a signals to control a standard servo motor (I used a Futaba servo but you can use any servo) using the 12F675 microcontroller.  You can type a text command into a serial terminal e.g Hyperterminal to set the position of the servo. The project software works slightly differently to the previous […]

IC Based H Bridge Tutorial1

IC-Based H-Bridge Tutorial

An alternative to using a transistorized H-Bridge circuit is the L298 Dual Full-Bridge Driver. It is very easy to control and it doesn’t require any calculation. Simply knowing your motor’s required current and the IC’s current capacity is enough. For a price though.In order to learn this, you need to first download the IC’s datasheet

TD-USB-02 interface with touchpad sensor board and WinAmp interface using PIC18F2550

TD-USB-02 interface with touchpad sensor board and WinAmp interface. This is an example USB project showing how to interface a touchpad sensor (the AD7142ACPZ) with a standard XP/Vista computer. The TD-USB-02 board with a PIC18F2550 communicates with: the PC: USB 2.0 through a mini-B connector. the touchpad sensor board: SPI over 8-wire flatcable. PC WinAmp

d.i.y. Handheld Multichannel Analyzer MCA based on 16F877 PIC Microcontroller and LCD

d.i.y. Handheld Multichannel Analyzer (MCA) based on 16F877 PIC Microcontroller and LCD

Some time ago I was developing a medical instrument which required histogramming, which got me in the mood to retake my own PIC MCA project(http://home.comcast.net/~prutchi/index_files/scint.htm ). I used the variable RAM in the microcontroller (16F877), so I limited the number of channels to 95 and let the histogram run until some channel reaches 240 counts (the
