2. 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.

If you’ve never worked with robotics before, this is a good time to examine how your bot was put together, how it can move, and start thinking about how you might mount your Arduino later on.

allowing you to send and receive data just as you would with an Arduino. There’s a real-time clock, servo headers, plenty of ways to power the board, and even a breakout for this GPS module.

The Arduino Servo Cat-a-pult looks to automate this rather annoying daily task. A pressure sensor mat — placed in front of your cat’s food dish — activates the device. Once the mat is ...

But if you’re going to really go far you’ll also need to get good at electronics, which was part of the reason behind this Arduino servo tester. [Peter Pokojny] decided to take the plunge ...

The batteries, for example, can be found online for about $15, while the servo motor ... to each other to put the car in motion using the code that is powered by the Arduino board.
