11+ Relay Arduino Schematic. Here we are not using any relay driver ic like uln2003 and will only use an npn transistor to control relay. The following schematic shows how to connect the module to an arduino, i have only shown one device.
Connecting a relay to Arduino | Make: from i1.wp.com
You can watch the following video or read the written tutorial below. This relay has 5 pins. An input section of the relay module consists of three terminals vcc, gnd, and a signal input (in1).
Assemble all the parts as shown in the schematic diagram.
