Using a very cheap ESP8266 controller and a simple PCB, we can lift the C64 into the modern era of having internet access. We evaluate two different WiFi modem firmware solutions, and I will show you how to connect to a BBS with gateways to modern websites. You can now read the news, look up things on Wikipedia, and most importantly: download software for your C64!

Let’s Code ESP8266: The SI7021 Temperature and Humidity Sensor
The SiliconLabs SI7021 is a very popular sensor for measuring temperature and humidity. It uses the I2C bus and is easily accessed from the ESP9266 or ESP32. Some breakout boards use different variants of the chip, namely the measurement Specialties HTU21D or even the Sensirion SHT21. These chips are more or less compatible to one another, but some don’t implement all the commands. However temperature and humidity can be used on all those chips. Today I’ll walk you through a tutorial of accessing the SI7021 via the Arduino Wire library.
