Please help me. I have found the same circuit from the following link.
The circuit designed by Mr. Richard Gideon. I have made a PCB out of it but no luck. I have following problems:
Following are my observations, please consult following PCB i made. I must mention that i have replaced 2N3904 with BD139.:
**broken link removed**
1- As per given conditions in sketch for Pot1 and POT2 the LED's can be set.
2- After setting, i found that The motor only rotate when the Right most LED(LED1) is in ON condition. When the LED 2 is On motor do not rotate. i.e. The motor rotate in only one direction. When i press Limit switch West side the motor stop.
3- The LED's react to the lighting environments.
4- Only one relay(the LEFT MOST)work the right relay do not work at all.
5- I checked closely the circuit and found that the right relay is connected wrong so i change the connections for RELAY-EAST as shown in attached picture.
**broken link removed**
6- After reversing the connection i connected to the power supply but still motor do not rotated in opposite direction
When i adjusted Trimpot 10K a smoke came out of it.
I am not electronic guru but if some one point to me in the right directions. How the connection to be made to the DPDT relay. Please down load the picture 1 and in a Paint program help me drawing rough sketch.
I didn't made schematic. I directly draw the PCB by manual tracing.
Kindly help me.
