How many actual bytes needed I do not know yet, bell scheduling required because of alarming of sessions in a day. For example, if I want to set three bells will ring in a day so I can set time of each bell and all three bells are stored in my desired block i.e P01. When I select P01 then...
Its help me but I need something different, only assumption, I need 24 EEPROMs and I can store 50 bells in each EEPROM and it should be in a single Arduino Mega2560.
Hi all,
I am writing a program in Arduino Mega2560, the program would look like scheduler alarming system, it has 24 program each program have 50 bells. For example, in a day 24 hours, we want to program 1 for 3 bells (but it has capacity of 50 bells can be scheduled). We go to menu select...
Hi,
I wrote a code for SPWM with the help of internet and others projects. It is successfully output SPWM signals and Mosfets Inverter circuit also have output but I learn only thing is output filter LC type. How to design LC filter?
I am using Arduino Mega2560 and IR2112 driver.
Carrier...
Hi all,
I have code for SPWM and it has Atmega328 Timer1 Mode 8 Phase and Frequency Correct PWM Mode it is working well with deadtime but I want some difference.
I require complimentary PWM output I done it output is complimentary output of PWM. Both complimentary outputs of PWM went to LOW...
Yes it is a programmable school bell with alarming system, there are different periods in school for different times.
A school bell should be looks like it has 24 programs, each program will be able to save 50 bells means we select program P-01
and in program P-01 we will save number of bells as...
I am only stuck in part of program where we goes to select Programs 01 to 24 then goes to next menu select total bells such as we select four bells then goes to next menu 1st bell menu opens now setting alarm time and file select then enter goes 2nd bell menu opens now setting alarm time and...
Thank you vishweshgm, doraemon and danadakk,
Summary is that I have to built school bell device which works as (please excuse my english is not good).
Where we can set 24 Programs each program contains 50 bells and setting of time(used RTC DS3231) when it will ring.
Program flow is main display...
Hi,
Using Arduino Mega2560, 16x2LCD, SD Card.
The project have 24 programs each program can store 50 audio mp3 (bells) files from SD card.
Programs are selected by push buttons up/down programs 01 to 24 , we go to menu choose program 01 to 24
if we select program 02 then go to next menu where...
