Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs. Microcontrollers are useful to the extent that they communicate with other devices, such as sensors,...
Interfacing a RelayA transistor usually receives a signal to the base junction from a CMOS or TTL system. The Raspberry Pi will usually provide 3.3 V to represent logic 1 output, whilst a TTL microcontroller will provide a 5 V output. In either case, the relay driver circuit...
Stepper motor interfacing with PIC microcontroller Schematic of a Relay Driver Circuit Using ULN2003 The internal circuit diagram of the relay driver IC with the Darlington pairs is given below. A clamped diode is used as a freewheeling diode to avoid the back-emf effect in the case of inductiv...

driver circuit using ULN2803 enables to use eight relays. The above circuit represents the interfacing ofPIC microcontroller(PIC16F877A) with relays using a relay driver circuit with ULN2003. The clamp diodes are built in these relays driver ICs and which eliminates the usage of freewheeling ...
The above figure shows the block diagram of practical three phase solid state relay with ZVS which consists of thepower supply block, microcontroller block, TRIAC set, and loads. The zero crossing feature of an Opto-isolator (which acts as TRIAC driver) avoids abrupt current inrush on inductive...
The smart relay has a microcontroller to cause actuation of a coil in response to receiving the authorization signal. The system may optionally include a relay simulator for interfacing with the smart relay.ACHAND, BERTRANDCHEVRETTE, GUY
