Analysis purpose and processI want to do the smart curtains is to achieve a function - early in the morning to pull their own, in the evening to pull themselves, simple and practical.The general process is:Collecting the light intensity data collected by the photosensitive resistor;Determine whether to open the motor, and determine the direction of motor rotation.As for why not do a APP on the phone, because the individual is more in favor of the smart phone is not the core of the future smart home system argument. I won't say it because I'm not
Hands on1 programmingBefore things come back, the first written procedures, the source code is as follows:[C] pure text view copy code
Preparation materialsTo achieve this function, materials include: external power supply (5V or more), photosensitive resistance, DC motor, L293D (H bridge) and some resistance, jumper.
Winter vacation contact with Arduino, do a smart curtain, send a post to write down the whole process, I think it is best to help you!
