I edited from Arduino Turn on Led Using Button by mehmetsukru

Originally, you hold the button (there's only one) the light will be on, and it will not light when released. I change to two buttons. One is for turning on the light, and another is for turning off, like a night light.

List:

Light bulb x1
Male to male breadboard jumper wires
Resistors x1
Arduino Leonardo
Breadboard
Buttons x2
A bag

Step 1: To Get Started

This is very simple!

Connect one button to pin 2 and positive electrode (+)
Connect another button to pin 3 and +
Connect 5v to the +
Connect GND to the negative electrode (-)
Connect one foot of the light to the negative electrode (-) , insert resistor's one foot on the same row (straight row).
Connect to pin 9 with the other foot of the resistor (straight row)
Use a bag to cover the wires

Assembly Completed!!
