DS18B20 1 wire communication LED temperature display 7

Image
Today we are all going to learn chip DS18B20 temperature. I Characteristics: The specification of the sensor DS18B20 can mention briefly as follows: • Use a wireless interface should just have one leg out to the media. • It is possible to measure the temperature in the range of -55 -> +125 oC.Voi temperature range -10 ° C to + 85 ° C, the accuracy of ± 0.5 ° C.Co temperature warning function sweeping away the value given. • Voltage: 3 - 5.5 V, you can configure multiple encryption level from 9-12 bits The greater the number of bits precision hon.Thoi conversion time is 750ms maximum temperature for 12 bit encryption • Current consumption in sleep mode tiny. • Each sensor has a unique identification code stored in memory 64-bit on-chip ROM (on chip), binary values ​​are laser engraved. • If configured for DS18B20 under 9,10,11,12 bit precision, we have respectively: 0.5 ° C, 12:25 ° C, 0125 ° C, 0.0625 ° C.Theo default manufacturer if they It is not configured mode, it will automatic...

PIC16F887 877 programming in C Tutorial 7 LCD Moving Display n Custom Characters

Image
LCD; Moving Display & Custom Character : You can display your custom characters by using mikroc custom character tool. Go to tools>>customer character then make the character you want to display. After this click on 'generate code'. It will generate a customchar function just copy and paste above the main function. customchar has two parameters; row and position in that row. Just pass these parameters where you want to see your custom character on LCD. You can also move the text, left and right, on LCD screen; by using the LCD commands. _LCD_SHIFT_LEFT and   _LCD_SHIFT_RIGHT are the commands. There are various other commands in mikroc, i forget to tell you in lcd tutorial, these are: LCD Commands Now lets write a code to display and move the custom character, back and forth, (of your choice) on LCD screen. Code: // LCD module connections sbit LCD_RS at RB4_bit; sbit LCD_EN at RB5_bit; sbit LCD_D4 at RB0_bit; sbit LCD_D5 at RB1_bit; sbit LCD_D6 at RB2_bit; sbit LCD_D7 ...

Apple Launch of iPad Mini 13 Macbook Pro Retina Display

Image
It looks like the iPhone 5 wasn't Apple's last big debut in 2012. Apple just sent out invitations to a special event that it's holding next Tuesday, October 23, starting at 10 a.m. PT, presumably to unveil the much-rumored smaller iPad model and a 13 inch MacBook Pro with Retina Display. The tagline of the invite is "We've got a little more to show you," and the invitation shows the top of Apple's logo. Apple is holding the event at the California Theatre in San Jose, Calif., just a block away from the courtroom where its major trial with Samsung took place. The invitation confirms a report from AllThingsDigital last week, which claimed the event date would be October 23.  Since before its very first model of the iPad came out, Apple has been rumored to be working on a smaller version. But expectations that the company would double down on its iPad line have increased, especially after competitors like Amazon and Google began to put out smaller tablets th...

7 SEGMENT DISPLAY COUNTER INCOMING PERSON COUNTER

Image
Hiii…….friends today I am here with a very interesting projects for those who have just started with electronics. With this project we can display 0-9 digits on the 7 segment and we can count the no of persons entering in a room.  Circuit Diagram Here a counter IC 7490 is used along with BCD to 7 segment decoder IC 7447. The function of 7490 is to provide the counting value and decoder IC is decoding that value to 7 segment output . Every time when you will push the switch the clock of IC7490 will be triggered and as a result count will increase by 1 . Hence with this simple project we can display numbers 0 to 9 on seven segment display just by pressing switch. It’s a very easy circuit and you can easily implement it on a general purpose PCB . NOW ITS TIME TO MAKE USE OF THIS CIRCUIT IN COUNTING THE NUMBER OF PERSONS ENTERING IN THE ROOM...... LETS SEE HOW….?? So instead of using switch we will use LDR here , we will place LDR at the entry door in such a manner that the shadow of t...
