I need some C-code examples of when the LM74 detects a temperature higher than the preset level set at e.g. 40 deg, a relay is switched on. Then when the temperature falls below the preset temperature, the relay is switched off.
Or anything similar to this would be a great help…
Iv been searching the net but can’t find anything, so would appreciate some help from you guys as this site has saved one of my previous projects before.
