TTP223 Touch Sensor – bu kichik va arzon sensor bo‘lib, teginishni aniqlaydi va raqamli chiqish beradi
U Arduino va boshqa mikrokontrollerlar bilan ishlash uchun juda qulay.
Asosiy xususiyatlari: Chiqish turi: Raqamli (HIGH yoki LOW) Tegishli kuchlanish: 2.0V – 5.5V Ishchi oqim: Juda past (standby holatda ~1-2 µA) Chiqish holati: Tegilganda HIGH holatiga o‘tadi Sensor chipi: TTP223B Tegish yuzasi: Modul ustidagi "TOUCH" deb yozilgan joy
Afzalliklari: Mexanik tugmalar o‘rnini bosadi (kiyim ostidan ham ishlaydi) Uzoq umr va ishonchli ishlash Soddalik bilan Arduino bilan integratsiya qilinadi;

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
What is Telegram?
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
