Hi guys, hope you could help me out as this is for an important school project.
So here is my problem;
I need to move a motor one direction when it's hot, move it opposite direction when it gets cold, now that part is OK, It's working that way with a simple thermistor circuit and a DPDT relay, but i need the motor to stop when limit switch is pressed.
Currently the two limit switches that i have inserted only turn the motor off when it is rotating clockwise and not anti clockwise. Here is how I wired it:
In otherwords it is semi working, when the motor turns clockwise Limit S2 turns it off, but when it turns anti clockwise Limit S1 does nothing, although Limit S1 turns it off when motor turns clockwise aswell, which is pointless.
Not sure if i'm explaining myself but hope there is someone here that could help me out.
Thanks in advance.
This is the DPDT relay i'm using http://www.rapidonline.com/design-te...-relay-60-4690
And the temp circuit i'm using is http://www.rapidonline.com/pdf/70-0315-Thermistor-temp-project.pdf although that works perfectly.
