Four channel ESP-01 WiFi based relay unit - Windows application uploaded to Sourceforge

[StuartPearson]

I have just uploaded the Windows (10, should works on earlier versions) executable for an application I have developed to control the outputs on the widely available ESP-01 based WiFi four channel relay units. I have been introducing it’s use into my photography to trigger the camera and external flashes, it’s available for anyone who would benefit it from its use. In addition to separate control of the individual relays, a timed sequence with a maximum of 12 steps can be created with the counter incrementing in 100 millisecond intervals.

The download link is: ESP-01 Four Channel Relay Timer Application

The relay unit is available from eBay and other sites:
