hi,
i am a newbie in this forum, as well as in electronics project. i have been working in a digi-lock project, the source of which has been taken from http://www.engineersgarage.com/micr...code-lock-with-password-using-at89c51-circuit.
i am using at89c52 microcontroller. the problem im facing here is I can't make the lcd display working. ive tried with the simplest ones, but nothing is showing in the lcd.
Supply in the microcontroller seems above 5 volt without joining the lcd, but below 5 volt while joining the lcd. im wondering if the voltage drop is causing for the problem with the lcd?
im really confused and disappointed already.
pls help me....plssssssssssss
