I am a beginner Electronics enthusiastic and I am trying to build a circuit and I kind of know how to go about assembling the circuit but I do not understand purpose of some of components in the circuit. I have attached an image of the circuit for your reference. http://www.futurekit.com/2009/manual/future/eng/PDF_FK9/fk945e-1.pdf
The circuit is "Digital Temperature Controller.
The Electronic kit seller did not provide a clear and through explanation of the circuit. Can someone help me with the explanation of the circuit. For example
- The Purpose of the Relay , npn Transistor (TR2 C458) , LED1 ?
-The Purpose of the combination ( R1, C1 , C2) on the left top part of the circuit ?
-The Purpose of the combination ( TR1 C9013, ZD1 5V1,C3,R23,D1 4001, C4 ) on the right top part of the circuit ?
Also , the document explains that "Jumping J1" is used as operation of relay.
UnJumped - relay will be working at the lower temp and stop working at the higher temp.
How can I make a change to the circuit so that it just reads tempreture.
Thank you So much.
