Interfacing PIC16F84A microcontroller with DHT11(RHT01) sensor This topic shows how to interface DHT11 (RHT01) digital relative humidity and temperature sensor with PIC16F84A microcontroller, and how to simulate this interfacing using Proteus. Note that for the simulation Proteus version should be 8.1 or higher. With these versions there is no need to install Proteus DHT11 library, […]

In digital electronics, fan-out is defined as the number of gate inputs that the output of a single logic gate can feed. It is very important in digital systems for a single logic gate to drive other gates or devices. In this case, a buffer can be used between the logic gate and the devices

Each of the output lines of a ‘508A microcontroller can deliver a maximum of 25mA. What does this mean? It means any device connected to the line must take 25mA or less. If it takes more than 25mA a buffer transistor (also called an amplifying transistor) must be used and this will be discussed in a

This design features a fourth generation programmable femtoclock that provides reference frequencies to replace crystals and SAW oscillators in high-performance applications. It is programmable through I2C interface. It has four selectable LVPECL or LVDS via I2C while its FemtoClock NG VCO ranges between 1.9GHz to 2.55GHz. It also meets the standard interface requirements of PCI
