This is a detailed guide to building a robotic camera pan and tilt system using Arduino or other microcontrollers. The guide covers the necessary components, including a BEC (Buck-Boost Regulator), 5V regulator, servo motors, a microcontroller (e.g., Arduino Compatible), STM32 Blue Pill board, Teensy 3.2, or other options, depending on budget and preferences. The article suggests using a cheap 7805 chip as an alternative to a BEC, although it notes that the BEC is generally preferred due to its lower heat generation. For the microcontroller, several options are listed, including: * **Arduino Compatible Microcontrollers**: Any Arduino compatible board will work, but it must fit within a specific area (20 mm x 60 mm) and meet certain requirements such as having at least one digital PWM pin and one digital pin. Examples include the STM32 Blue Pill board and the Teensy 3.2. * **STM32 Blue Pill Board**: A cost-effective option that fits within the required area and meets the necessary requirements. It can be found on Aliexpress for around $1-2. The article also covers other components needed for the project, including Dupont breadboard jumpers, thin hookup wire, a 9V battery, a 9V battery connector, a small male and female connector (e.g., xt-30), and two M3 screws.
