Step 7Wire Up the LEDs
The top and bottom row of red LEDs are wired together, and the 6 yellow side LEDs are wired together. This allows the circuit to blink between red and yellow alternatively.
The positive leads are all connected together, and will be connected straight to the positive battery terminal. I plan on using 2 AAA rechargeable batteries which create 2.4 volts. The rated voltage drop of the LEDs I was using is 1.9 to 2.5 volts. Since the supply voltage and LED voltage drop are practically the same, I used the smallest resistors I had, 3.3ohm. A resistor was soldered to each negative lead.
