UPDATE: code posted below Nike+iPod is a very interesting piece of hardware for all kinds of reasons, not the least of which is that it as actually useful. It works by wirelessly transmitting data from a sensor (that is stored in your shoe) to a receiver that is either externally connected to your iPod or to …

In this another tutorial on sensors for beginners, we are going to interface single and multiple Infrared IR sensors with Arduino Uno development board, working simultaneously and have the status displayed either on an ( 4X16 LCD ) LCD module (jhd162a) or an LED. We are going to cover three chapters in single tutorial in simple …

This is an old design. Some of the components may be difficult to buy. If you would like to build an even better and cheaper A/D converter, take a look at the new PICADC3 design. The PICADC is a simple 12-bit, 8-channel analog to digital converter (with 4 additional digital inputs), which may be connected to the PC …

Temperature and relative humidity are two very important ambient parameters that are directly related to human comfort. Sometimes, you may be able to bear higher temperatures, if there is a lower relative humidity, such as in hot and dry desert-like environment. However, being in a humid place with not very high temperature may make you …
This project uses one of the smallest chips in the PIC microcontroller range, the PIC12F629 and you can learn to program it and experience the thrill of making something yourself and see what goes into writing a program. Even a program as simple as this one is not easy to put together and if you …
The microcontroller used is 0822 zilog encore! 8k series (soic,28pin) as shown on the figure. Is a programmable microcontroller, the functions used are the GPIO and the UART of the chip. GPIO is used on led indicators, and the UART is used for giving and reading AT COMMANDS to control the Bluetooth device. Controller board …

This simple project uses a Dallas DS1820 one wire temperature sensor and a pic 16f628 microprocessor. A simple temperature regulator where a LED symbolizes the Fan. Data derived from the DS18s20 is a 9bit centigrade temperature measurement. As mentioned the temperature sensor communicates over a one Wire bus that requires only one data line and ground for communication with a …
Over the last few months I have prototyped and built a water tank level sensor for my 9000L rain water tank. The design is based entirely on Silicon Chip’s PIC-Based Water-Tank Level Meter, but instead of programming PICs, I prototyped using an arduino, and built the final version using PICAXE microcontrollers. The sensor consists of …
