hello sir, wat i meant was, i am using HC-SR04 sensor, and the output i expected is when distance between the ostacle and the sensor is less than 75cm, the buzzer beeps fast, when the sensor is placed in between 76cm and 120 cm the buzzer beeps at moderate speed, and wen the distance of ostacle...
i'm sorry for being silly and not providing he accurate info, by the way this is my circuit, and basically my project is ultrasonic ranging system.

hello everyone, recently i have programed an ultrasonic detection system with pic18f1330 to detect obstacle, i want to make it portable, this i have make use of powerbank
But the problem arise when i use 2600mah the output is not as i wanted but if i use 10000mah the output i s as i wanted, can...
can anyone provide me with PWM coding in C to control led brightness for pic18f1330?i was using pic18f4580 previously, but here in pic18f1330 the port is totally different and i'm facing some difficulties here. thank u :)
I have fix my code to test Hc-Sr04 sensor and its working fine, but there is one problem i'm facing now. which is the output(LED) is not light up as bright as it should even without resistor, but it is very dim. Even i test with voltmeter it shows 5v in the output pin. But when i test it with...
i write a code to test my HC-SR04 sensor to measure distance but seem there is no responce from the sensor, after i program and when i turn on the pic, the LED from port A0 turn on and not turn off even i move more than 100 cm..pls help
i'm using pickit 2, mplab ide wit c18 compiler, internal...
hi, currently i'm working on a new pic, p18f1330. bt previously i was using p18f4580 and my coding works fine, but wen i convert it to port in p18f1330, its not working, pls help..my project is using ultrasonic hc-sr04 sensor. whereby the distance measured will be display in hyperterminal and...
[PIC] if else convert to case problem
i have some difficulties i converting if else to switch statement
pls help me with this, is it posibble to use variable case?
if(distance>=0 && distance<=250)
{
LATDbits.LATD0=1;
}
else if(distance>=251 && distance<=500)
{
LATDbits.LATD0=1...
thank you sir, i wil try it. i'm using mplab ide wit c18 compiler and pickit2. is my conection for circuit is correct?

its still not fuctioning sir.. :(

is my circuit diagram is correct??
i am new to pic18f1330, i have written a code to test that the pic18f1330 works fine, but i can't get it work even for simple led on/off coding, please help me regarding this. I have attacted th code together with the connection of my pic. scared it was the wrong part..thank you
#include...
thanks ud23

thanks for your advise sir, but i have a problem here, im doing a portable sensing system for blind, since its portable i want to make it consume as less power as possible, it ther a way to doit without a switch?
Good day everyone,
currently im doing a project, ultrasonic sensor based project. an ultrasonic range detector.
i wish to make it a portable so that it can be powered by battery. The problem here is, i wan to make it to consume less power so that the battery can last long
Is there anyway to...
