1.a.ii.1 Relay Driver

Note: the visual “fritzing” diagram has been removed for now since it doesn’t show the relay we have in stock; please follow the schematic and the notes below.



The 5V relays in our lab are model HASCO KLT1C6DC5 (datasheet).
Here is a picture from the datasheet that shows you the pin assignments:

Here is a picture of the actual relay with the pins labeled and numbered like we see in the schematic.


This component is not made for a breadboard, but if you are careful you can make it work.  Here is a picture of the component pushed into a breadboard with jump cables whose colors correspond with the labeled picture above.  We didn’t have black jumpers so that black label and grey jumper go together.
