An External Pulse Counter Using 8051 and Dispalying on 16x2 LCD
A circuits which is used to count the external pulses And which is displaying on an 16x2 LCD display . You can simply use this project for various purpose .It is a default project for counting Purpose.
Tutorials : -
To use 16 Bit counter we need to configure some register in 8051 as follows
TMOD Register is need to configure as follows
16 bit counter Setting with timer 0
TMOD=0x05; // Giving 0x05 it configured so .
8051 has Two Timer (each has 16 bit ) i am taking here Timer 0 It has to part First 8 bit (TL)) and the second part is (TH0) .
This timer is using to store the Pulses from the external (ie it will increment up to 65535 or FFFF)
TL0 = 0; // that timer clearing
TH0 = 0; // that timer clearing TR0 = 1 // TR0 setting to start the counting . Done ................................. After setting the above register as said the resulted value (counting value ) will save periodically in TL0 and TH0 . That value displaying after converting it to decimal . for LCD Tutorials Go Here

I need to make a counter for a transformer winding machine .In that the winding is made by hand . so the roation need to be keep in mind ,that is too much difficult .So the winding shaft rotaion counting by an infrared sensor module which is connected with 89S52 microcontroler and a LCD .
Infrared based Rotation Counter by 805 or (contact less Rotation Counter or Rotation counter without using Interrupt.

Here Atmega16 measuring the current and voltage by inbuilt comparator .Previous post described how to read ADC value click here . Two ADC port is used PA0/ADC0 is measuring voltage .And PA1/ADC1 is measuring current .
We have to measure 0 to 12 volt, but controller can only read as maximum voltage 5 volt . Hence a voltage divider circuit used to reduce the corresponding voltage level at a mximum 5Volt.
take Vin = 12volt Vout = 5 volt. Assume one of the resistor value and find out the other . *********************************************************************************** we have to measure current ,But we cant directly measure the current . there are more technique to measure the current. we uses a shunt resistor method .
The millivoltmeter voltage is taken and calculated by some equation and displayed as current .for more click here For example . According Ohm's law, 0.1 Ohm resistor under 1A current will give 0.1V voltage drop *********************************************************************************
design circuits to feed controller for current and Volt. the whole project can be download Below including proteus file For downloading click below Download

Bit 7 used to ADC ON (ADC Turn ONing by applying a high bit )
Bit6 ADSC is used to start the conversion .and still maintain it value as high up to the conversion . after conversion it becomes low (Zero)
ADATE and ADIF is not used by me now .(not by using Intruppet
Bit 0 to bit2 is used for select ADC frequency .
\
2) ADC: It is a 16 bit to 8 bit register ADCL & ADCH. By applying right shift value it is autmatically set as normal value so we can take simple value from it
eg : return (ADC);
adc_value = read_adc(ch_sec);
The program as follows . The full program can be download below including Proteus simulation file.
