TI introduces world’s first multichannel inductance-to-digital converters

Texas Instruments (TI) announced the world's first multichannel inductance-to-digital converters (LDCs). The four new devices in the LDC1614 family expand the innovative LDC portfolio, a data converter category that TI first introduced in 2013. The devices offer two or four matched channels and up to 28-bit resolution in a single integrated circuit (IC). The combination of precision and multichannel functio ...

Contactless Digital Tachometer using PIC Microcontroller

Hey friends, I should have posted this project last month itself  but there was some problem with the circuit. [link], author of this project did an exellent job. I have been watching him learning on this website. He came as a total noob but now he is well versed with 8051 and PIC microcontroller. earlier he has submitted Microcontroller Based Home Security System This project is about A Contactless Digital ...

DIGITAL CLOCK CIRCUITS

A Digital Clock can be made easily by using PIC Microcontroller, DS1307 and a 16*2 LCD. I have already posted about Interfacing DS1307 RTC with PIC Microcontroller. The DS1307 RTC can work either in 24-hour mode or 12-hour mode with AM/PM indicator. It automatically adjusts for months fewer than 31 days including leap year compensation up to year 2100.  DS1307 comes with built-in power sensing circuit which ...

6 Digit LED Clock

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz crystal. The displays I used are SA23-12SRWA, which don’t appear ...

Lab 2: Basic digital input and output

Description Today we will learn how to read digital inputs from a push button switch. A digital input has only two values: 1 and 0. The configuration of the push button switch is same as that of the reset switch except it goes to a different port pin. The status of the switch will be read through RC1 and every time when it is pressed, an LED connected to RC0 will be toggled ON and OFF. Required Theory You m ...

Digital Temperature Sensor Circuit

Temperature sensors are widely used in electronic equipments to display the temperature. You can see the digital clock displaying the room temperature value. It is due to the temperature sensor embedded in it. Generally, temperature value is analog. It is converted to digital value and then it is displayed. This article describes the same converting analog value to a digital value. Digital Temperature Senso ...

IR Digital Thermostat for FAN

Introduction  This circuit measures temperature in Celsius scale and displays it on an alphanumeric LCD screen When temperature rise to 40 C an alarm is activated and at the same time a relay is also activated which drives a fan to keep the temperature at a level. Another feature of this circuit is that you can use the keys "1,2,3,4" of a Philips TV IR remote to turn on or off three relays, The key '4' is u ...
