Project: How to connect the elements of the circuit

1.- Materials

• Tin

• Wire
  

2.- Recommended Tools:

• 1 x soldering iron
  
• 1 x wire stripping tool
  
• 1 or 2 x pliers
  
• 1 x tweezers

3.- Some recommendations:

• The soldering iron and the tin have to be holded by the same student.

• Tinning the tip of the soldering iron

• Tinning the end of the wires and contacts. Once you have tinned both parts, you are ready to solder them together.

4.- Soldering elements:
SPDT Switches
Soldering the SPDT switches I (1. NC with NC and 2. NO with NO)
Soldering the SPDT switches II (3. C with Motor and 4. C with Motor)
Soldering the SPDT switches III (5. (+) battery holder with NC and 6. (-) battery holder with NO) On your AA battery holder you have a red and a black wire. The red wire is positive ( + ) and the black is negative ( - ).

7.- Motor with Switch and 8. Motor with Switch.
9.- Switch with battery holder.

Solder the wire like on the picture and everything is ready to be tested.

Put some battery in it (3 AA batteries)
Both motors should turn.
By pressing the left SPDT switch the left motor should turn the other way.
By pressing the right SPDT switch the right motor should turn the other way.

 

If they don't, CHECK EVERYTHING!
