Hi,
Can someone please help me with LPC2148 Slave receiver coding
as I'm working on a project where LPC2148 is slave and Raspberry is Master
Help appreciated
Thanks
Ya I'm using UNO to control 2 dimmers .
Noise is just a hunch
What may be the other reasons?
ya I'm using I2C from Raspberry Pi to send data to UNO to control the dimmers connected to UNO

Filtering means how? any suggestions plz?
Nope,I'm using 230VAC and Incandescent...
Hi,I'm working on a project where I'm using 2 dimmers and giving input to control the dimming of loads
But getting a problem when I connect both the loads to 2 different dimmer modules and 1 load dimming is effecting 2nd load dimming
I think this may be due to noise in dimmers but unable to...
Guys now its working fine,actually the circuit I gave works perfectly
but now I'm getting a new problem that is
if i have 2 dimmers and running simultaneously then the dimming of 1 load is effecting the 2nd load
what may be the issue ? (its due to noise from dimmer circuit, but from where I...
This is my original connections with dimmer & relay module
They are main wire connections which are present in switch board
Yes those are commands from MCU
The relay is driven from MCU as shown in the figure through MCU Pin 4
Thanks for the replies and for solutions
Hi #Pjdd
I've tried your circuit and even here the same thing is going on, without the relay being ON the dim level can be set to 50 or any value(similar to what's happening in my circuit)
The circuit operation goes like this:
Input:Dim On > The Relay connected to dimmer should ON and the load should be at full power
Input:Dim 50 > The load should Dim to level 50 (half the power to load)
Input:Dim Off > The Relay & load should OFF
What's happening according to my circuit is, even...
Thanks for the reply
I've connected to "NO" too but when I've done this the circuit wasn't working. Even I'm unable to understand the reason why it isn't working
Not only that relay connection but the other relay connections of my board are also not working when I connect it to "NO"
Help me...
Hi,I'm making a PCB where I should connect my Dimmer module to Relay so that I can ON/OFF the dimmer using relay and even control the dimming.
Now I'm getting a problem where my dimming is happening even when Relay is OFF
These are my connections, please help me through this connections if...
Hi,now my dimming is working without any fault or damage of resistors when I replaced 0.1uF cap by 0.1uF/275VAC
But I'm still getting 0.4V @MOC3021 and 1.09V @4N35
And guys help me with the circuit I've attached where relay is also connected,the problem is when I send some instruction even...
Sorry, even I'm unable to understand because now its showing as 0.53V but mostly its showing 0.0V (its always been varying)
but dimming is happening
so what may be the issue ?
