An LED Persistance Of Vision Name Badge using PIC16F88

An LED Persistance Of Vision Name Badge This Instructable shows a name badge that I have built for my daughter. I have seen the Defcon badges, and thought they were cool. Why cant my kids have one as well - but specially built for them? So here you go - A simple badge that uses a PIC 16F88, and a handful of LEDs, and flashes your child's name in lights when they shake it, or push a button. I have left space ...

PIC16F88 Delorme Tripmate GPS Logger

This project focused on creating a simple serial data logger for the Delorme Tripmate (also known as the GPSTripmate). The Tripmate is an older GPS receiver that can be purchased on eBay for <$20. I happen to have one that my family used a couple of years ago and it is still in great shape. It has been sitting in the back of my car for the past four years, so I finally decided to put it to good use. The ...

Water Wave/Tide/Level Meter 2.0 using PIC16F88

Capacitance Probe A simple probe can be made using insulated wire. The insulation is then the dielectric of an cylindrical capacitor with the inner conductor as one plate and the water as the other. The probe is not suitable for distilled or very pure water because it is not conductive enough. It works well even in relatively clean water such as roof runoff water in a plastic tank. PVC plastic coated multis ...

Minidot 2 – The holoclock using PIC16F88 microcontroller

Minidot 2 - The holoclock Well maybe holoclock is a little bit inaccurate....it does use holographic dispersion film on the front to give a bit of depth. Basicaly this instructable is an update to my previous Minidot located here: http://www.instructables.com/id/EEGLXQCSKIEP2876EE/ and re-using a lot of code and circuitry from my Microdot located here: http://www.instructables.com/id/EWM2OIT78OERWHR38Z/ Eag ...

Universal Serial Infrared Receiver using PIC16F88

You can use this Universal Infrared Receiver (UIR) project to control your PC:  Starting Windows programs,  setting the Windows volume control,  even moving the mouse around the screen! All at the touch of a button - with your TV remote control in fact! It uses a PIC microcontroller to characterize the demodulated infrared signal and then transmit it as a serial data stream to the PC. Software running on th ...

Sonar range finder using PIC16F88 Microcontroller

The PIC sonar range finder works by transmitting a short pulse of sound at a frequency inaudible to the ear (ultrasonic sound or ultrasound). Afterwards the microcontroller listens for an echo. The time from transmission to echo reception lets you calculate the distance from the object. PIC Sonar Specification Range ~5cm - 300cm Accuracy +/-3cm Transducer frequency 40kHz nternal oscillator frequency 4MHz Th ...

Making a binary clock using a PIC16F88

You can use a PIC microcontroller and an LED matrix to create a binary clock (or if you prefer you can wire up individual LEDs). This project uses an LED matrix block as it saves lots of wiring.  So what is it ? Its an led clock that displays the time information as binary numbers... ...and it is a good way of learning how to read binary (well up to 9 any way!). You can represent the numbers 0-9 using 4 bin ...

Serial LCD Module using PIC16F88

Many times when I'm working with a small MCU such as 8 pins or 18 pins MCU. I found that I don't have enough MCU pins for parallel LCD display. So it's good to have a one-pin-require LCD module for experiment. Acctually, serial LCDs are sale on the market but still I built it myself becasue I can do it and it's cheap. It's a very simple schematic, I use PIC16F88 becasue It has internal oscillator and Usart ...

How to drive an led display matrix using PIC16F88

Here you can find out how to drive an led matrix with 64 LEDs (8 rows by 8 columns - 8x8 display) or less e.g. 35 LEDs (7 rows by 5 columns - 5x7 dot matrix). It uses persistence of vision to let you drive the 64 led matrix with only 10 microcontroller outputs! Normally you would need 64 outputs for 64 LEDs but by using multiplexing and a helper chip you can get away with 10. LED Display multiplexing simply ...

A Real Time Clock using PIC16F88 Microcontroller

This PIC project uses an I2C Real Time Clock IC (DS1307) and a four digit seven segment display to create a standard desk clock. Note: If you typed DS1703 Real Time Clock to find this page you probably mis-spelled the chip type. Anyway you can find a DS1307 (RTC) Real Time Clock IC project and information here. Real Time Clock IC : DS1307 Although the PIC16F88 has a built in oscillator for a 32kHz watch cry ...
