so that you can drive them, we want special present motorists. Motor relay board comes in to the picture as a result of these needs. Engine relay board drives engines and relays by providing adequate present. It may drive one relay and four DC engines or one motor that is stepper a time. The engine relay board eases the job of interfacing motor that is external AC products utilizing the ATmega32 microcontroller. This has ULN2003 motorists for high applications that are current motor driving and relay driving circuits for AC unit interfacing.
You will find three primary parts for an engine relay board.
Making use of the supplied relay circuit, 230V products may be managed. This part is useful for automating the off and on.
The DC motor may be managed by using this area, there clearly was 4 ULN2003 driver managed lines for driving motors and every provides enough present to manage 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 making use of SW1, energy LED will glow. * Connect the slot connector into the standard slot. * Shunt the jumpers in J4. * Use jumper caps to pick pins that are port. First four pins (0, 1, 2&3) are relay selectors.
