    It should be problem with the circuit that you have made. Try to find the problems with your project.

    I can see from the picture that your lcd not even get initialized. Check all the pin connections of lcd. Check the voltage on R/W pin, it should be zero. Also adjust (reduce) the contrast by adjusting the variable resistor connected to pin3. Try increasing the delay slightly wherever it is used.
