This will be another video about Arduino, my friends. We wont be speaking about the biggest Arduino this time, but rather the worlds smallest Arduino: Attiny85! Let’s prepare the Arduino IDE to work with Digispark’s Attiny85 module and implement a temperature and humidity monitor with the possibility of an adjustable trigger. Our assembly is very simple: we have the well-known DHT22; the Attiny85, a chip that can be smaller than the SMD voltage regulator; and an i2c OLED display.
I want to make it clear that I chose the Attiny85 module from Digispark because I found it easier to handle, but it is fine if you want to program only the Attiny chip. However, you’ll need a serial USB converter.”
