Diodes are the oldest and most elementary semiconductor. They are also among the most useful, and there are a variety of diodes to do everything from convert AC to DC to detecting radio waves and to producing light.
Today we wil take a look at diodes. We’ll see how they work, and how to use them.
Since its introduction in 2016, the ESP32 has become one of the most popular microcontrollers in the world. It has now grown from a single ESP8266 replacement chip into a complete line of powerful microcontrollers and communications modules.
Today we will look at the status of the ESP32 as of January 2024. We will also take a look at a new Alpha of the ESP Boards Manager for the Arduino IDE.
After 12 years, Arduino has released the latest edition of the classic Arduino Uno. Actually, it’s two boards, the Arduino Uno R4 Minima and the Arduino Uno R4 WiFi.
These boards are 5-volt logic devices and are physically compatible with the older Arduino Uno R3 boards, preserving your investment in shields and prototyping equipment. In addition, they offer many new features, several of which we’ll examine today.
