Hi, this is a circuit of a li-ion charger based on the principle of a crowbar. One thing I am not getting is the use of the TIP32 PNP transistor. What is the use of TIP32 and why a 1N4148 diode is connected in reverse polarity?
Though I had not tested for line following robot but you can use Proteous with Infrared Library for simulation.
Here is the link for library of infrared library.

Every projects contains circuits but some contains PCB, Author Prototype.
For LCD:
Pin three (3) is Vee and is the difference in voltage between VCC (+Ve) and VSS (Ground). This LCD voltage is adjusted to provide the sharpest contrast. Vee must be lower then Vcc and higher then ground
This 3000W inverter circuit with inbuilt charger may help you.
This inverter circuit is designed using AT89c2051

I had made wireless mobile charger circuit posted in best engineering projects, but the problem is low current. The current output is about 250mA at 5V which is much less to charge any mobile. I want to increase output current do you guys have any solution.
I had attached my prototype with...
There are two ways of connecting GSM module to arduino.
1. you may connect the Tx pin of GSM module to Rx pin of Arduino and Rx pin of GSM module to Tx pin of Arduino. (while programming Arduino you have to disconnect wiring in Rx and Tx each time you burn the program to arduino.)
2. Use other...
If we use 1st stage amplifier then poles are located as s=+/-1 which is corresponds to an unstable system. Similarly if we use 2nd stage amplifier there would 4 solution i.e. four pole at 45, 135, 225, 315 degree. no poles at 0 and 180 degree.
so if we use 3rd stage amplifier it is better suited...
While searching for 5 band equalizer circuit i found a website. I have inserted link below. In that article they used this formula for finding the value of components.

At first i would like to define you what is accuracy in ADC?
accuracy of the ADC determines how close the actual digital output is to the theoretically expected digital output.
Sentence "A 2-bit ADC with 10 bit accuracy" means an 2-bit ADC produces 2*2, or 4 output codes where 10 bit accuracy...
Basically we found center frequency by subtracting initial frequency from final frequency i.e. F0 = F2-F1.
But while surfing internet somewhere I found a formula of center frequency (f0) = 2CV.
The thing i am not getting is that
what C and V represent for?
From where this formula came from?
Thanks.
If you are looking for unique frequency assigned to button of remote then this post will help you.
It will show you the frequency in HEX code and you can further utilize that code in receiver unit. the figure in below show you the HEX code of remote button.
For complete documentation you may...
Which MCU you are going to use? if it is PIC18F4520 then here is code for you
