- Elio Mazzocca Capacitive sensing is a versatile technique that can solve a difficult sensing problem in a surprisingly simple manner. For example, it can be used to turn a liquid-metal thermometer into the sensing element of a thermostat. Such ...Mar 23, 2011
- Introduction Digital timer switches are used to control the operation of electrical devices based on a programmed schedule. This project describes a programmable digital timer based on a PIC16F628A microcontroller from Microchip that can be ...Feb 10, 2011
- Magirescu Iulian Introduction In the first place, a relay is like a switch to a coil assembly. This switch is activated when electricity is applied to the coil. With a common relay, the electricity must be continuously applied to the coil to ...Dec 15, 2010
- Circuits Automation Measurement MCU Open-Source Platforms Microcontrollers Usage Arduino Arduino Arduino Pro miniEric Ayars Overview The Arduino Pro Mini is a microcontroller board based on the Atmel ATmega168 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and ...Dec 12, 2010
- Mechanics This is not the best mechanical system and I am always open to new ideas and suggestions. Originally I started out with a plastic worm gear and plastic 50 tooth gear, always in contact with each other. Then one day I forgot the gears were ...Oct 20, 2010
- Andy Collinson Description: This hybrid circuit uses a mixture of transistors, an IC and a relay and is used to automatically open or close a pair of curtains. Using switch S3 also allows manual control, allowing for curtains to be left only ...Oct 20, 2010
- Software PIC Software The PIC software is written in assembler and based on earlier projects using I 2 C interfaces. The EEPROM, PIC and external connector all share the same I 2 C bus and the PIC will not use it unless the thermistor is fitted. ...Jun 1, 2010
- Andrew M. Bishop Description This project uses a Microchip PIC microcontroller, a serial EEPROM and a thermistor to create a temperature recorder. Performance The temperature is measured and stored at user programmable intervals; this can be from 1 ...May 12, 2010
