Section 10: CONTROLS

This section deals with adding the switches, pushbuttons and rotary encoder.

Slide switch S1 is added as shown in the photo below.  Make sure the switch sits flush against the board before soldering. Be sure to solder the mounting tabs as well, as some mechanical strength will be important.  

The four pushbuttons PB1-PB4 are added next. You'll note that the pushbuttons can be inserted in either of two orientations - it doesn't matter which way is chosen. You'll also note that the legs of each pushbutton are formed to hold the component n place after insertion. These bends in the leads can cause some problems if you're not careful.  A way around this is to straighten the bends out as shown on the right, using your needle nose pliars.

Just make sure the pushbuttons sit flat against the pc board before soldering them fully into place.

The leads for the miniature speaker SPKR are first straightened out (the come pre-bent at 90-degrees) and then inserted to the pcb at the designated position at the bottom of the board.  Note the polarity of the speaker by the small plus sign ("+") on top the device, as shown below.  The speaker should be oriented with this indication at the top. 

The speaker will naturally sit several millimeters above the board - don't try to push it down closer that it will reasonably be forced.  When soldering the speaker leads in place, take extra care not to use excessive heat, as the plastic of the speaker body will easily melt and can result in a non-functional speaker.

The rotary encoder slips neatly into its location on the board.  Be sure it sits flush to the board and then first solder the two mounting tabs.  Then solder the three leads for the encoder.
