Hi, I think the solenoid is functioning at 220VAC. What do you mean with contact supressor? Is it the diode accross? Yes I have them.
I'm reading an analog voltage on the RA0 of the PIC.
Is it possible to create two grounds in just one power source? I'm thinking about the ground of the...
Hi cameo_2007, please suggest any diagram?
The transformer that feeds my power supply rectifier is rated with 24VAC 1.5A
Please check my attachment
Yes these are present.
I am using MY4N it's from OMRON
I'm using PIC18F4620
Thank you for your help guys :)

Resetting happens whenever the microcontroller activates the relay that turns on the solenoid valve for controlling the pressure passage. Microcontroller controls the relay through 4n30 opto isolator. The whole circuit shares the same power supply which is approx 31VDC (from 24VAC). 31VDC is...
Sorry I forgot to include that I'll be using 3 extra port pins to drive relays and 1 pin to read analog voltage
I tried calculating the pins that will be used and it would be 9pins(5x4 for 20 push buttons) + 11pins(Controlling LCD) + 11pins(controlling 20 LEDs using multiplexing like driving...
Hi edaboard, I am planning to build another application but this time it is a bigger one. I'm having problems about choosing the microcontroller that could/must be used. I'll be controlling 20 LEDs, 1 LCD display and 20 push buttons. ROM, RAM and processor speed here is critical so I'll choose...
Hi, I'm using C18 and everything works fine. Compilation succeeded. But the problem is I'm encountering thousands of warning messages on Proteus. Here's the same warning message:
PIC18 EXEC) PC=0x0032. Attempt to execute illegal opcode (loaded from PC=0030). Instruction executes as a NOP...
I've just started playing around with MPLAB C18 but I can't seem to make it work. I'm using this code.
#include <p18f4620.h>
#include <delays.h>
#pragma config OSC = XT
#pragma config WDT = OFF
#define LEDpin LATDbits.LATD1
#define LEDTris TRISDbits.TRISD1
void main()
{
LEDTris = 0...
Hi, I tried the circuit above but as I increase the number of strings the current on each string decreases too. I used 0.1uF Cap and 1K 2W resistor. The total current only is 150mA. :cry:
Help pls?
Very thank you for the circuit Brad theRad but my objective for the design is to have parallel leds so that when one led goes down I won't have a hard time on finding the broken LED and I could replace it easily. If I'll be using this kind of setup for parallel LEDs like for 1 string I have 2...
Hello BradtheRad, that's one option I have in mind also but I can't juice out a current as high as 1A from that kind of setup. I tried to use this setup
but I can only get a maximum current of 100mA. Will it help if I increase the capacitance?
