Today,we have some work that accomplish IC.We have to fulfill it on project board.If we carry it out,the speaker on projectboard will sound.The LED on the project board will shine on and off.At first,I think that it must be easy . I will finish it quickly. As time pass,I begine to feel angry. The electric parts are so weak that I always ruin them.Electric parts are small that makes my eyes tired easily.I must pay all attention to it ,or I can not finish it. Finally , I finish it ,but it can not shines and sounds. I feel very sad . I have to do it again .Fortunely ,when I accomplish it again, it sounds and shines sunddenly.The smile appear on my face gradually.
