Hi Friend !!
Myself Sheshmal ,is in pune . I am in embedded fron 1.5 years.
Nice it this site . definitely it is helping to the millions.
Right now can u please help me regarding the ULN2803 interfacing ti the microcontroller.
I am giving the supply to the IC as 5V DC. and expecting the working of the IC. But it is not working!
When any input is not given to the input pin then i think it should be treated as logic 0 and output should be logic 1 . bot i am getting 1.4V , when i gives logic 1 (5V) at input then i am getting .49V at the outpot !
I am really astonising that what is this happening ! Is there any extra modification is required ?
or in real sense it should be checked with relay ?
or IC may be faulty ? if we consider it as faulty then same thing is happening to many ICs ?
Please help me yar !!

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
