to be able to drive them, we are in need of unique present motorists. Motor relay board comes in to the photo as a result of these demands. Engine relay board drives engines and relays by providing enough present. It may drive one relay and four DC engines or one motor that is stepper a time. The motor relay board eases the duty of interfacing outside motor and AC products utilizing the ATmega32 microcontroller. This has ULN2003 motorists for high present applications like motor driving and relay driving circuits for AC unit interfacing.
You can find three sections that are main an engine relay board.
Utilising the supplied relay circuit, 230V products may be managed. This section is useful for automating the off and on.
The DC engine could be managed by using this part, there was 4 ULN2003 driver controlled lines for driving engines and every provides adequate present to regulate the DC engine.
* Terminal block (3pin) вЂ“for linking relay IN and OUT * Terminal block(7pin) вЂ“ for linking 4 lines of engine, 1 for energy and 2 pins for ground
Linking the Board
* switch on the board SW1 that is using LED will glow. * Connect the slot connector to your standard port. * Shunt the jumpers in J4. * Use jumper caps to pick pins that are port. First four pins (0, 1, 2&3) are relay selectors. The relay may be attached to 4 pins. * Use port pins 4,5,6&7 for engines in the near order of engine D, C, B&A. * Set the input port pin correspondingly to make ON/OFF the relay/motor.
