Arduino and Relay Module Hookup<\/figcaption><\/figure>\n

This morning I hooked the whole thing up to the MTR-12, wrote the software, and did some testing.<\/p>\n

Software:<\/strong><\/p>\n

For the test software, I added a couple of routines to the lamps program. First, I added the processCommands()<\/em> routine to accept commands through the serial(USB) port. I wanted to be able to send it a switch number, and have the unit turn that relay on for a brief period of time. As brief as possible. It also has to tell me that the switch has been turned on, so I know what is going on. This routine is only for testing the functionality. I also added the setSwitches()<\/em> routine to turn the switches on (and off.)\u00a0 This routine also let’s me know when a switch has been turned off.<\/p>\n

I have made an array of integers called switches[] and set them all to be zero. If the processCommands() routine receives a number, it changes the appropriate switches[] element to be 500. Every time the Arduino goes through a loop, it calls the setSwitches() routine and, if any of the switches are not zero, it pulls the appropriate relay module pin LOW, thereby activating the relay, and the switches[] element is decremented. Once the switches() element reaches zero, the appropriate pin is pulled HIGH again. This will allow me to see how long the switch needs to stay on in order to trigger the action. 500 loops should be a good starting point.<\/p>\n

Here are the new setup()<\/em> and loop()<\/em> functions:<\/p>\n
