Temperature sensors are used in a wide range of electronic devices, including digital thermometers, home thermostats, ovens, and refrigerators. Figure 1 shows two devices with temperature sensors. Figure 1. Devices with temperature sensors. The temperature sensor provided in your kit is a precision analog sensor, whose voltage output is linearly proportional to the temperature. Configured […]

A Microchip PIC based servo controller offering many of the capabilities of digital servos for under $9! The controllers capture the r/c receiver output, optionally manipulate the samples, then regenerate new servo control signals. As such, they greatly enhance what is possible with cheap servos. They were created for my Steam Turret Tank Instructable. Here […]

The BTS or Base Transmitter Station is the device that transmit the POCSAG messages to the pager. It is the radio interface of the POCSAG network. THE HARDWARE The current version of the BTS hardware is a small board with a pic 18F microcontroller with a firmware that receive commands through an UART/RS232 port, create […]

The notion of building a monitor/speaker AV tester came up in the forums a few weeks ago. Someone requested to see a project devoted to testing VGA displays and Speakers. The project I made many years ago: The VGA Test Box can be used to test displays, however it is large, clunky and not friendly […]

How to turn and ordinary external harddrive into a datalocker using only a PIC microcontroller, a keypad and some various other components. Step 1: Parts The parts you need: – 3.5″ SATA harddrive enclosure – 2.5″ SATA harddrive NOTE: This will not work with a 3.5″ IDE enclosure and a 2.5″ IDE drive without a […]

description Add general purpose input/output lines to your computer based projects. This circuit is a 12 pin digital GPIO interface using the Microchip PIC18f14k50 microcontroller which connects to an USB host port. The microcontroller is available in through-hole DIP20 and SMD packages, too. Circuit diagram The device is powered by the USB bus. 12 port […]

First of all, if you have any questions, feel free to comment! I’d be more than happy to answer your question as good as possible!! Materials used : – PIC 18F452 Microcontroller ( any PIC microcontroller with enough pins will do ) – 7 Segment common anode LED display – 24 Mhz Crystal – A […]

jump to a section:supplies about LED arrays design construction customizing/programming washing and wearing troubleshooting and FAQ **NOTE** As of Fall 2007, skip the ugly microcontroller programming (don’t buy the STK500 or the AVR chip)… Get a LilyPad Arduino instead. It’s much easier to sew and to program! See my LilyPad Arduino tutorial for help on […]

An eight pin Microchip PIC microcontroller is programmed to operate from a 32768 Hz watch crystal and output waveforms which, when displayed on an oscilloscope, show the time in HH:MM:SS format. The screen capture shows winscope showing 12:46: … Step 1: Design the character set On an oscilloscope screen, vertical axis (up and down) corresponds […]
