2, compared with the Xiaomi wireless charging treasure 10000mAh currently on sale, the youth version is basically consistent in appearance design, but the new black and white color choice is more young and fashionable. The shell material is changed from metal to plastic, and the function is slightly reduced, so the price is reduced by 20 yuan.
2, the digital thermometer designed by this system uses DS18B20 digital temperature sensor to measure temperature wireless charging display clock , DS18B20 direct output is the digital signal, compared with the traditional thermometer, with convenient reading, wide temperature measurement range, accurate temperature measurement, upper and lower limit alarm function. Its output temperature is displayed by LED digital tube, which is mainly used for more accurate temperature measurement places.
3, the digital timer is generally composed of oscillator, frequency divider, counter, decoder, display and other parts. In this design, 555 oscillator and its corresponding external circuit constitute the standard second signal generator, and the timing system is composed of counters, decoders and displays of different bases. The second signal is sent to the counter for countingThe cumulative results are displayed in 'hours',' minutes' and 'seconds'.
4, display display control scheme and controller selection scheme optional. (4) It is not allowed to use LED integrated driver module and integrated gray level generation module, available CPLD or FPGA.
5, in the program design, in each LED conversion and 7 segment code output, turn off the bit selection signal (PC output 0b11111111), eliminate the display of the trailing phenomenon (shadow elimination function). T1 design: T1 is a 16-bit timer, the system clock is 4M, and its 64 frequency division is adoptedThe later clock is used as the count signal of T1 (register TCCR1B = 0x03), a count period of 16us, 2ms need to count 125 (0x007D). 6, Abstract: digital electronic clock circuit design system, with AT89C51 single chip microcomputer as the control core, by keyboard display, timing alarm, LED common cathode digital tube and LED light display and other functional modules. Based on the basic requirements of the topic, the system focuses on the design of time display and timing alarm. Most of the functions of this system are realized by software, which absorbs the idea of hardware softwareShow how to close '> Xiaomi wireless charging speaker display how to close

Setting steps: Open the Xiaoai App, click the profile picture in the upper right corner, click the gear (setting) in the upper right corner, turn on the Bluetooth device, click the connected Xiaomi wireless charger Bluetooth speaker, find the option to turn on/off the "Xiaoai charging clock", and set the start time/end time in the "Clock setting" option (the "Xiaoai charging clock" option is turned on by default, and the default time period is from 9:00 to 19:00.
2. Perform the following stepsSet the time to display: open the millet phone [Settings]. After entering the "Setup" page, drop down the page, find the "Display" option and click to enter. Click to enter 【 Screen Preview 】. Turn on the switch behind the screen preview to display information such as the time, date, and notification. You can also set time to open, automatically open/close the screen preview.
3, first download the Xiaomi audio app, click the top right corner profile picture. Then click the gear in the upper right corner (setting), turn on the Bluetooth device, click the connected Xiaomi wireless charger Bluetooth speaker, and connect the speaker with the app. Finally, set the clock in the app.
4, first open the Settings, find Xiaoai classmate; Select ai key in the Settings, select long press to wake up; Then find the wake up Settings, click on the right to close the small love classmate can be. Mi 9, is a mobile phone owned by Xiaomi, the internal code name is Battle Angel, using 39-inch Samsung AMOLED water drop screen, equipped with Qualcomm Snapdragon 855 flagship platform, up to 12GB memory 256GB storage.
1, there is a time control switchClock key: After pressing this function key, adjust the clock to the current time.
2, music lamp want to connect with the mobile phone, you must first turn on the lamp, and then turn on the mobile phone to search for nearby devices, and play music after connecting with the lamp.
3, this technology intelligent desk lamp, first say its eye protection function, there are 5 modes can be adjusted, according to their own use of the lamp to choose.
4, the charging port and the opening key are in the lower part of the audio, and the operation of the audio body is extremely simple, on this one opening key, short press is to turn on the audio, long press is to turn off the audio, without adjusting the volumeIf you want to adjust the volume, you need to connect the phone to the stereo Bluetooth first, and then adjust the volume key of the phone.
5, Yes. A few light wireless charging music desk lamp can be opened for a night, a few light desk lamp designed with weak sleep light, will not stimulate our eyes, and has a light pole that can adjust the Angle, it doesn't matter when you sleep all night.
