PIC microcontrollers are popular among hobbyists due to their flexibility, low cost, and ease of use. They come in various models with different form factors, pin numbers, and memory sizes. A programmer is needed to program the microcontroller using C language. The AVR microcontroller is a similar option, while the Arduino platform is easier to program for beginners.
A peripheral interface controller (PIC) is a type of microcontroller commonly used by hobbyists and inventors. A PIC microcontroller typically has between 20 and 60 pins that control input and output from the microcontroller. They are usually integrated into a printed circuit board and programmed using the C language. PIC microcontrollers are inexpensive, flexible, and easy to use, making them a popular choice in microcontrollers.
There are many types of PIC microcontrollers available. The differences between the different models are the form factor, the number of pins and the amount of memory. Dual inline package (DIP) is usually preferred by PIC hobbyists, because it’s easier to work with and can be easily added to a breadboard. The quad flat no-leads (QFN) package is typically used in industrial settings, because it is more compact. Most people won’t use all the pins or memory in their PIC microcontroller, so there’s no need to buy a top-of-the-line microcontroller.
A hobbyist will usually plug their microcontroller into a breadboard or circuit. A breadboard is easier to use, but the circuit is preferable in more permanent applications because it’s more compact and durable. Inputs and outputs such as motors, LED lights, and sensors can be connected to circuit or breadboard pins. These can then be controlled by the PIC microcontroller.
To program a PIC microcontroller, you need to have a PIC programmer. These are typically much more expensive than the microcontroller itself and connect to the microcontroller via the USB or serial ports on a computer. Microcontroller programming is also done via C. Programming usually consists of getting inputs and outputs from pins. It is generally quite difficult for a beginner to program a PIC microcontroller, although it can be learned through books or online tutorials.
The PIC microcontroller is similar to the AVR microcontroller. These are the two most popular choices for microcontroller enthusiasts. Neither of these microcontrollers are a clearly better option. Both are cheap, programmed in C, and similar in appearance.
Another option to consider is the relatively new Arduino® platform. It is an open source project based on the AVR microcontroller. It’s significantly easier to program an Arduino® than a PIC microcontroller, so it may be a better choice for someone without much programming experience.
