This is the meaning of stepping, its motor is called stepper motor, can be like a person walking, a short section at a time, the amplitude of each section, the length of time between the two sections can be adjusted. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Connecting these small steps is a complete action, as long as the interval time and stride length are adjusted, there will be no interruption. Your stride is too big, so there will be a sense of pause in several places, so make the stride smaller and the frequency faster. ”

There is basically no one on the third and fourth floors during the day, and the internal security has received a notice from Zhang Yuanyuan that they will not stop Hong Tao and Dong Cai. Today, Hong Tao is teaching Dong Cai how to arrange the actions of the computer lamp by himself, and now he can't learn it systematically from scratch, so he simply let Dong Cai ask the problem first, and then help her solve it herself, linking study with daily work, which can be regarded as a crash course.

"It's all in English...... Master, if you write down the Chinese, I'll stick it on and look at it, so that you don't have to memorize the words. "It's a bit difficult for Dong Cai to learn these things that she hasn't used before, because she basically doesn't know English, and the settings menus of these devices are basically English abbreviations, and if you don't know them, you can't adjust them. Hong Tao's method was to ask her to copy down all the abbreviations according to the parameters on the instructions, and then add the original text to the back, and then memorize these words. Dong Cai must not be willing to carry it, so he began to think of various ways to deal with it lazily.

"I don't teach people who don't memorize words, I'll come back in two days, this word must be memorized, I'll check it first, and then I'll go to class when it's over. By the way, who blinded the bubble of the computer lamp? "It's impossible not to memorize words, Hong Tao himself also started to learn from memorizing words, since he has been uncomfortable, then others can't be easier than himself, otherwise he will be very depressed, torturing this little apprentice is also one of the joys of life." However, the computer light controller made him frown again, and the self-test program of one of the lamps had not passed, and the light bulb was broken.

“…… I didn't mean to, a few days ago I planned to turn on a light to practice, but it didn't light up when I used it......" Dong Cai was hit badly by memorizing words, and when he heard Hong Tao ask about the computer light again, his voice was lower. She also knows that this kind of bulb is not cheap, and it will break down within a few days of opening, if Zhang Yuanyuan knows, this scolding will definitely not be avoided.

"Are you switching too many times?" Hong Tao didn't plan to sue this apprentice, she could take the initiative to admit her mistakes is a very good performance, if the bulb is broken, it will be broken, isn't there a backup.

"I'll turn it on and off three times, it won't be so squeamish, right?" Dong Cai didn't know why he would break the light bulb, and he didn't think that he could achieve this effect by switching it a few times, if so, this computer lamp would not be a defective product.

"Why I won't explain it to you, remember what I said, turn it on when you come to work, don't turn it off later, when you get off work, when you turn it off, so that you don't break the light bulb. In any case, you broke it, I can not sue, but I can't spare you. Go to the storeroom and pull the elevator out, and I'll teach you how to change the bulbs. As soon as he heard Dong Cai's tone, Hong Tao knew that the light bulb was broken. This kind of high-voltage xenon bubble needs a warm-up time to start working through the high voltage, if the frequent switching, the preheating is insufficient, the high-voltage electricity will instantly emit huge heat, and if it is not good, the electrode will melt, and then it will never light up again. This situation is inevitable, and now it's not for Dong Cai not to touch the computer lamp, but to let her know more.

"Master...... It's a bit high...... "Dong Cai was quite excited when the hydraulic elevator was just started, and it was estimated that she was sitting on this thing for the first time." However, when the ladder was raised to a height of more than three meters, she held on to the railing and did not dare to look down, and her face became more and more pale.

"You still need to say that of course your master and I are taller than you!" Hong Tao deliberately laughed with her, trying to distract her. Seeing that her virtue is not like a fear of heights, it's just that she doesn't adapt to it, so it's okay, and she has to exercise more.

"Bang dang...... Oops, master, I can't stand up......" When the elevator stopped, it would make a noise and vibrate, and now Dong Cai simply didn't stand up, and sat directly on the platform.

"I'll count to three, and if you don't get up again, I'll climb down and cut off the power myself, and you can sit on it. "I want to play tricks! It's easy to do, Hong Tao directly stepped one leg out of the railing and made a gesture to leave.

“…… It's too high, scared!" Dong Cai immediately got up from the platform and hugged Hong Tao's leg that was still on the platform. She doesn't have to try any virtue as a master, I don't know if he dares to climb down and throw himself on it, maybe he will have to shake the elevator below.

"You can't stand up! If you want to cry, you can shed tears, or if you don't cry, don't howl. Look, now I'll tell you how to change the light bulb!" Hong Tao took back the leg that stepped out, and then grabbed Dong Cai's neck collar and pulled her away from his lap, and then began to use a hex wrench to disassemble the cabin cover under the computer lamp, and show Dong Cai the details of disassembling and assembling the light bulb.

"Remember, wear gloves when holding a light bulb, if it gets sweat and dirt on it, it will crack easily in high temperatures, try it yourself. Hong Tao did it again, and restored the broken bulb again, planning to let Dong Cai try it himself, it was useless to just see if he didn't do it. When I watched it, I thought I could do it, but I found that I still couldn't do it in many places.

"I can't reach it!" Dong Cai grabbed Hong Tao's clothes with one hand, and planned to grab the lampstand with the other hand, but unfortunately her height was too different from Hong Tao, Hong Tao's head was already on the lampstand, but she was still a few centimeters away from touching it. The elevator can't go up anymore, the handrail on the platform at the top of the ladder is a bit high, and if you go up again, it will reach the lamp.

"Alas...... You said that you should be taller and less distracted! Hong Tao is also out of line, the next time she comes up to change the bulb by herself, she has to bring a stool, otherwise she still can't reach it. Don't go down to get it this time, let's suffer by yourself, hold her legs and lift her up.

"Hey, hey, hey...... Higher...... "Dong Cai is also a goods with a lack of heart, his face turned pale with fright on the elevator just now, and now he is held by Hong Tao and his thigh is lifted half a meter higher, but he is not afraid, and he is still happy.

"Master, am I right?" Dong Cai is short and not fat, it is estimated that she is only about eighty pounds, and it is not very difficult for Hong Tao to hold her. She also learned things very quickly, and quickly changed the light bulb, and when she was put down by Hong Tao, she actually hugged Hong Tao's neck with both hands, and wrapped her legs around Hong Tao's waist, and hung on Hong Tao like a koala to play.

"Hey, you let me go! If I don't let go, I'll throw you down......" Dong Cai may not have realized it, but Hong Tao knew very well that this posture was too ambiguous. The faces of the two people are still so close, even if she is a tomboy, but after all, she is a girl, and she has all the places on her body.

"I'm not going to come down...... I won't come down......" Dong Cai was not afraid of Hong Tao's unreliable threat, not only could he not come down, but he also hugged his arms and legs tighter.

"I won't let you come down!...... Oh, don't come down!" Hong Tao had no choice, he could only control the elevator to descend with one hand, and slap Dong Cai's ass with one hand. Dong Cai screamed when he was slapped, but it didn't sound like a scream.
