Connect one of the servo’s yellow signal wires directly to Arduino pin 9, and the other servo’s signal wire directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4. 3.

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

The chips on the Arduino Uno cost around $4 USD and can be removed with a IC puller, then you can connect the Arduino’s RX/TX to the IC’s TX/RX, and then connect the reset pins as RST->RST ...
