Project 2 – Through-hole Soldering

Step 1: The Components1

Step 2: Insert LED all the way through. Positive leg to the left.2 Step 3: Bend legs out 45 dergrees.3 Step 4: Solder4 Step 5: Insert resistor and bend legs out.5 6 Step 6: Solder the resistor in place through both of its holes. THEN add some solder to connect the right LED leg to the left resistor leg (the middle two wires).7 Step 7: Snip off the two inner leads and test with a 9V battery. Remember which end is positive (+).8 9 10 Works with a Coin cell battery too. Just dimmer.11 12
