You need to power the TTP223 with a LDO 5v voltage regulator. It's 3 pins, very easy to use. Something like this: https://www.amazon.com/AMS1117-5-0-Step-Down-Voltage-Regulator-Module/dp/B078BCCDN1/ref=sr_1_9?hvadid=78340321331955&hvbmt=be&hvdev=c&hvqmt=e&keywords=5v+ldo+regulator&qid=1572735548&sr=8-9 . Then, the output of the TTP223 should go to the gate of a BS170, like this: https://www.amazon.com/FAIRCHILD-SEMICONDUCTOR-Fairchild-Channel-MOSFET/dp/B0797PWYYS/ref=sr_1_3?keywords=n+mosfet+transistor&qid=1572735935&s=automotive&sr=1-3 . You'll want to use a load resistor with your 3 LED's in series, and, subtract 7.2 - (3 * forward_led_voltage) to find the remaining voltage that you'll then need to current limit with a resistor. (Or, see this article…

(Or, see this article: http://www.learningaboutelectronics.com/Articles/N-channel-MOSFET-switch-circuit.php or this one: http://iamtechnical.com/n-channel-e-type-mosfet-switching-leds) Note that, depending on your LEDs' forward voltages, you may not be able to put them in series. The forward voltage may be too high, and a typical "9V" alkaline battery only puts out 7.2V. Also, if you use different color LEDs, you can't put them all in parallel and have a single current-limiting resistor. One of them (red, most likely) will have a lower forward voltage than, say, a blue, so the blue will never turn on. Don't ask how I know that :-) .

Wow! Wowsity WowwowWowWOOOWWWW! Sliced bread has nothing on Crazy Circuits, this is the greatest thing! I can't wait to read all about it! You're an inspiration! I LOVE this!!!!

Thanks! I will!
