Project Description:
********************
If you are just getting started with the ATtiny85 microcontroller then I highly recommend watching my first video, because if you want to program this tiny microcontroller using the Arduino IDE then first of all you will need to burn a bootloader on the ATtiny85 microcontroller and besides this, you must also know about its technical specifications, how to add the ATtiny85 microcontroller in the Arduino IDE, and how to externally power up this microcontroller. I have added a link in the description if in case you want to learn about the most basics things.

Anyway, in today’s episode, we are going to make a Temperature and Humidity monitoring system using the most popular DHT21 Temperature and Humidity sensor, and the I2C-supported SSD1306 Oled display module.

Instead of using the DHT21 Sensor, you can also use the DHT11 Temperature and Humidity Sensor. If you haven't purchased a temperature and humidity sensor yet, then I would recommend that you buy the DHT21 sensor. Because it’s fast and accurate compared to the DHT11 sensor. I have used these sensors in several beginner, intermediate, and advanced level projects.

Normally, I use the same Adafruit_GFX.h and Adafruit_SSD1306.h libraries when I use the SSD1306 Oled display module with the Arduino Uno, Arduino Nano, ESP32, and ESP8266 etc. But in the case of ATtiny85 these libraries didn’t work. So, later in this video, I will explain; which libraries to download and how to use them.
So, without any further delay let’s get started!!!
