+# Parts List
+- 1x Arduino Nano V3 5V 16mhz atmega328p
+- 1x 74HC00 Quad 2-input NAND gate (or 74LVC1G00 for a Single gate rather than a Quad gate)
+- 2x 2N4401 transistors
+- 6x 1K Ohms transistors
+- 1x 1 to 10 Ohm transistors (can be replaced with a jumper or '0ohm' directly but a resistor make the circuit safer!)
+- 2x B10K Potentiometer 0931
+- 2x 2mm to 5mm Leds
+- 1x 7805/78M05 5v voltage regulator
+- 1x 100nF capacitor (104)
+- 1x Diode (minimum of 20v), can be 1N4002, 1N4004, 1N4148, etc..
