"This means stepping. Its motor is called stepping motor. It can walk a short section at a time like a person walking. The amplitude of each section and the length of time between the two sections can be adjusted. Connecting these small steps is a complete action. As long as the interval time and stride are adjusted properly, there will be no interruption. Your set of movements is that the stride is too large, so there will be a sense of pause in several places. If the stride is reduced, the frequency will be accelerated."

There are basically no one on the third floor and fourth floor during the day. The security guard has received a notice from Zhang Yuanyuan that he will not stop Hong Tao and Dong Cai. Today, Hong Tao is teaching Dong Cai how to arrange the computer lights by himself. Now he can't learn it from the beginning, so he simply asked Dong Cai to ask questions first and then help her solve them himself, linking study with daily work, which is a crash course.

"It's all in English... Master, why don't you write down the Chinese and I post it on it and read it, so you don't have to memorize words." Dong Cai learned these things she had never used before, because she basically didn't know English. The settings menu of these devices are basically English abbreviations. If you don't know them, you can't adjust them. Hong Tao's method is to ask her to copy all the abbreviations according to the parameters in the instructions, add the original text to the back, and then memorize these words. Dong Cai was definitely not willing to memorize them, so he began to come up with various ways to deal with them.

"I won't teach people who don't memorize words. I will come again in two days. I must be able to memorize this word. When I come, I will check it first and then go to class. By the way, who blinded one of the computer light bulbs?" It's impossible not to memorize words. Hong Tao himself started learning by memorizing words. Since he has been uncomfortable, others cannot be more relaxed than himself, otherwise he will be very depressed. Torturing this little apprentice is also one of the fun of life. However, the computer light controller made him frown again, and one of the self-test programs failed, and the light bulb was broken.

"...I didn't mean it. A few days ago, I planned to turn on a light to practice, but it stopped lighting up as I used it..." Dong Cai was hit hard by the fact that he memorized words. When Hong Tao asked about the computer light, the sound became even lower. She also knew that this kind of light bulb was not cheap, and it broke one a few days after opening. If Zhang Yuanyuan knew about it, she would definitely not be able to avoid this scolding.

"Did you turn the switch too many times?" Hong Tao didn't plan to complain to this apprentice. It was a good sign that she could voluntarily admit her mistake. If the light bulb breaks, it would break. Isn't there any backups?

"I just turned it on and off three times, it won't be so slutty, right?" Dong Cai didn't know why he broke the light bulb, and he didn't think that the switch could achieve this effect in a few times. If this is the case, this computer light will not be a defective product.

"Why don't I explain to you? Remember what I said, turn it on when you come to work, don't turn it off in the future, and when to turn it off when you get off work, so that the light bulb will not be damaged. No matter what, you broke it. I can't complain, but I can't spare you. Go to the warehouse to pull out the elevator, and I will teach you how to change the light bulb." As soon as I heard Dong Cai's tone, Hong Tao knew how the light bulb was broken. This high-voltage xenon bubble requires a preheating time to turn on the high voltage and start working. If there is frequent switches and insufficient preheating, the high-voltage electricity will instantly emit huge heat. Maybe it will melt the electrode and then it will never light up again. This situation is inevitable. It is not to ask Dong Cai not to touch the computer light now, but to let her know more.

"Master... is a bit high..." Dong Cai was quite excited when the hydraulic lift was just started. It was probably the first time she had sat on this thing. However, when the ladder rose more than three meters high, she held the railing and didn't dare to look down, her face getting pale and paler.

"You have to say this. Of course, my master is taller than you!" Hong Tao deliberately joked with her, trying to distract her from the spotlight. Her virtue is not like acrophobia, but she is not very adaptable. There is no way out and she must exercise more.

"Bang...Oh! Master, I can't stand up..." When the elevator stops, it will make noise and vibration. Now Dong Cai simply stops standing and sits on the platform.

"I'll count three times. If you don't stand up, I'll climb down and disconnect the power supply. Just sit on it." I want to cheat! It's easy to deal with, Hong Tao directly stepped on one leg outside the railing and acted to leave.

"...It's too high, I'm afraid!" Dong Cai immediately got up from the platform and hugged Hong Tao's leg that was still in the platform. She didn't have to try her virtues anymore. Maybe he really dared to climb down and throw himself on it, and maybe he had to shake the elevator down below.

"You can't stand up! If you want to cry, you shed tears, and don't howl. Look, let me tell you how to change the light bulb!" Hong Tao took back his legs, then grabbed Dong Cai's neck and pulled her away from his legs. Then he began to use a hex wrench to remove the nacelle cover under the computer light, and demonstrated the details of disassembling and installing the light bulb for Dong Cai.

"Remember, you have to wear gloves when holding a light bulb. If there is sweat and dirt on the light bulb, it will easily crack in high temperatures. You can try it yourself." Hong Tao did it again, and restored the bad light bulb back, intending to let Dong Cai try it with his own hands. It is useless to just watch but not use it. When he saw it, he felt that he knew it. As soon as he started to operate, he found that he still didn't know many places.

"I can't reach it!" Dong Cai grabbed Hong Tao's clothes with one hand and planned to grab the lamp holder with the other hand. Unfortunately, her height was too different from Hong Tao. Hong Tao's head was already pressed on the lamp holder, but she was still a few centimeters away from touching it. The elevator could not be raised anymore. The handrail on the platform at the top of the ladder was a little high, and it would be pushed to the lamp if it was lifted.

"Oh... you said how long you grow, how good you are to be more careful! You're quicker, I can't hold on for a long time." Hong Tao had no choice. Next time she came up to change the light bulb by herself, she had to bring a stool, otherwise she wouldn't be able to reach it. Don't go down to get it this time. It's better to suffer the consequences yourself. Hold her legs and lift her up.

"Hehehe......it's higher..." Dong Cai was also a foolish person. He was so scared that his face turned pale on the elevator just now. Now Hong Tao was holding his thighs and raised them half a meter higher. Instead, he was not afraid anymore and he still had leisure and joy.

"Master, am I right?" Dong Cai was short and not fat, probably only about 80 kilograms. It was not difficult for Hong Tao to hold her. She learned things very quickly and quickly changed the light bulb. When Hong Tao put it down, she actually hugged Hong Tao's neck with her hands, and her legs wrapped around Hong Tao's waist, and hung it on Hong Tao like a koala.

"Hey! Let go of me! If you don't let go, I'll throw you down..." Dong Cai might not have noticed it, but Hong Tao knew very well that this posture was too ambiguous. The two people's faces were so close. Even if she was a tomboy, she was a girl after all, and she had everything she should have.

"I won't get off...I won't get off..." Dong Cai was not afraid of Hong Tao's unreliable threat. Not only did he not get off, but he also hugged his arms and legs tighter.

"I told you not to go down! Slap... Oh! I won't go down!" Hong Tao had no choice but to control the elevator down with one hand, and slapped Dong Cai on the butt with the other hand. Dong Cai called out with a slap, but it didn't sound like a scream.
