Prototyping with Microcontrollers, Sensors, and Materials

Prototyping Prototyping involves the creation of an initial model of a product to conduct testing. Whether the product is intended for consumers, government entities, or businesses, it typically starts as a prototype, which may not include all the components or functionalities present in the final market-ready version. Prototypes act as proof of concept, demonstrating that

How to work with inbuilt ADC Module of PIC18F4550

A microcontroller, a digital device, can read, execute and transmit only digital signals. On the contrary, the outputs of the most of the transducers are analog in nature. Thus it is hard to interface these transducers directly with controllers. Analog-to-digital convertor (ADC) ICs are one way to make the analog input compatible with the microcontroller.
