How do you use ULN 2803 with relay?
To use a ULN2803 with a relay, connect the relay's coil to one of the ULN2803 output pins and the other side of the coil to a power supply that matches the relay's voltage. Connect one of the ULN2803 input pins to a control signal (typically from a microcontroller) to activate the relay. Additionally, connect the ULN2803's common pin to the power supply ground to facilitate the internal clamping diodes that protect the IC from voltage spikes generated by the relay when it is de-energized. Finally, ensure that the relay's specifications do not exceed the ULN2803's current and voltage ratings.

What is the use of ULN 2003 Relay driver?
The ULN 2003 and the ULN 2803 are similar devices. The 2803 was the more popular choice because it required fewer external components. The ULN2803 is a small integrated circuit that contains 8 transistor driver channels. Each channel has an input to a resistor connected to the base of a transistor and a 1 amp open collector output capable of handling up to about 30volts (if my memory is correct). Each of the collectors has a reverse biased diode connected to a common Vcc pin that provides inductive spike protection. The ULN 2003 is identical other than the resistors feeding the base of the transistor. It is up to the designer to add suitable current limiting at the base of each transistor, normally a resistor added externally. Typical uses are for micro-processor interfaces to relays, lamps, solenoids and small motors. A 2803 with a set of relays is a simple and effective way of switching mains voltages for example. They are used less commonly today but were once an almost universal means of interfacing processors to power devices.
