With the DS18B20 temp sensors and using a 08m2 chip, can 3 x DS18B20 sensors be used, with one on each of C.1, C.2, C.4.
From what i understand from the manual this is doable, in the past i have only needed or use 1 sensor on a picaxe.
Application.............
I have some solar hotwater panels i intend to add to the present HW system, and need to monitor water temp from the panel, and water temp to the panels, for a circulating pump control.
A 3rd temp sensor might be used to monitor storage cylinder (tank) temp.
I do have I2C temp sensors that would allow up to 24 sensors on the same bus, and no harder to code, but the I2C sensors are SMD and harder to attach to locations.
Before the thread turns into a Caution of controlling mains power with a picaxe, i am more than able to safely do that control, and not harm any picaxe or person in the making or operation.
