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;

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
Spiking bond yields driving sharp losses in tech stocks
A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year.
A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
