Microcontroller Block Diagram, Working and Applications

Let’s see block diagram of microcontroller in detail. microcontroller is a compact electronic device that integrates a central processing unit (CPU), memory (both RAM and ROM), input/output (I/O) ports, and various peripherals onto a single integrated circuit (IC chip) for specified tasks. Unlike general-purpose microprocessors found in personal computers, microcontrollers are designed for specific tasks […]

Arduino with temperature sensor – Interfacing LCD and LM35

Let’s see how to interface Arduino with temperature sensor. LM35 is a three-terminal temperature sensing device. It is used to measure temperature in the range of -55°C to 150°C. It is a three-terminal device that produces an analog voltage proportional to the temperature of its surroundings. We can convert the analog output into digital using […]
