PIC16F84/16C84 Mini Programmer

PIC16F84/16C84 Mini Programmer
As new microcontroller chips appear on the market, today’s microcontroller programming tools are becoming more and more ‘universal’ to cope with different programming conventions. It is also sadly the case that the more ‘universal’ the programmer, the more you need to pay. In practice, most people will only use a fraction of the capabilities of such a programmer, making it difficult to justify such an expense.The project here describes a minimal solution to the programming problem for one of the most popular types of controller.
