Simple Water Level Controller Using IC-4049 and IC-555

Here, I am going to show you that, how you can make a simple water level controller using IC-4049 and IC-555.

IR Sensor Circuit Using LM358 - Simple

Here, I am going to explain the working of simple IR Sensor circuit. We know that the white surface reflects all the radiations which falls on it whereas black color absorbs them. When the supply is given to IR Sensor, the LED starts emitting light radiations. If the surface is of white color then it reflects all the radiations. As these radiations start falling on the photo diode, which is connected in reverse bias, the resistance ofthe photo diode

Interfacing of LED wiht AVR - ATMega16

Hi friends, Today I am going to tell you, how can you interface an LED with AVR (ATMega16). Here I am using only one AVR microcontroller ATMega16, one register(10K), one capacitor(16uF/25v), One push button switch, Led BAR Green in stead of 8 led's, power supply of +5v and -5v. Make the circuit as in diagram. Below is the circuits diagram and code for blink of the led will given below:

Simple FM Transmitter Circuit

Hi, friends, Today I am going to describe of FM transmitter. You all listen FM radio stations on your mobile. In this post i tell you that how can you make own FM radio stations.

 FM radio is one the most important marketing place for advertisement. So try it, it is useful for you. The range of this FM transmitter circuit is about 100meters at 9V supply. The circuits of FM transmitter and also the parts or components of this circuit are as follows.....

IR Receiver Circuit Using 555 with TSOP 1738

Hi, friends Today I am going to describe you about the TSOP 1738 and its schamatic circuit using 555 timer IC. Previous I posted the working of IR Transmiter Circuit. 

You can use that circuit using this circuit. When the 38 kHz signal emitted by IR LED, the signal sense by the TSOP 1738 IR Receiver and the high output is acheived at the pin no 3 of the 555 IC which is used by the uC to start target devices.

IR Transmitter Circuit Using 555

Hi, friends, Today I am going to describe the working of Simple IR Tx circuit using 555 IC. You also know about this is called as timer IC. It is used here in astable mode. 

In this circuit IR LED is used to generate a frequency of 38kHz which is received by IR Rx Circuit to generate a high pulse.

 And you use this high output of the IR Rx circuit to operate devices connected to microcontroller.

ISP Prog ver1.4

Hi guys,
Today I am going to tell you the link where you can dowload the ISP Prog ver1.4.
It is designed for only four ATMEL chip for programming.

Today I will also tell u how u can use this. Follow the procedurefor Prgramming following chip:
