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 […]

MTM Scientific, Inc… PIC Project for CATV Tuner
The CATV Tuner sold by MTM Scientific, Inc can be used for wideband audio and video reception, as described on our other project pages such as the FM Wideband Receiver and Radio Telescope Project. A common requirement in all these projects is the need to program the CATV tuner with a serial bit stream to […]
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 […]
PIC 16F88 Digital Thermometer Light Meter and resistance ohm meter.
PIC 16F88 Digital Thermometer Light Meter and resistance ohm meter. My original idea for this project was simply to try and interface the WINTEK WD-C2401P lcd panel to the pic (see my previous post). I figured it would be fun to add a couple of ADC readings to display something useful on the lcd. Theory […]
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 […]
New Microchip PIC32 Microcontrollers Run at 72MHz
CHANDLER, Ariz., Nov. 5, 2007 – Microchip Technology today announced the new Microchip PIC32 family of MIPS 32-bit microcontrollers (MCUs). The Microchip PIC32 is based upon the MIPS32 M4K Core, a high performance core with 32 core registers that are each 32-bits. Microchip has extended the functionality of the M4K core with some unique proprietary […]
Christmas card with inbuilt retro video game for under $10
Hello all and welcome to my second Christmas related project. Have you ever received a really boring Christmas card? Have you ever sat there and thought to yourself “If only there were a little video game on this card that I could play…” Well ponder no more because that card is here! This instructable will […]
Kaossilator 2 hack: hands free (part 1/2)
This is my first instructable…. ever. So here it goes. I own a Kaossilator 2 (KO2). It’s fun little phrase synthesizer and simple looper. But it has this awkward issue with mic button. When you want to record something from microphone you have to hold down two buttons simultaneously. First the mic button to enable […]
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 […]
Chromation Systems RGB LED Tube Light
Built utilizing a 24 Channel High Current USB LED Controller to control 12 volt RGB LED Light Strip, in 8 separate groups. Each group has individual 8-bit PWM which can create over 16 million colors. And is driven at full current for maximum color saturation and accuracy. Using the ColorMotion Compatible Firmware, various colors patterns and effects can be created […]
