In this tutorial's activities, the pushbuttons you add will be used to control the lights from LED Lights [1]. You will also use the alligator clip probes to test continuity between pushbutton terminals and voltages at key points in pushbutton circuits.
Green, yellow and red LED circuits connected to P13, P14, and P15 from Blink Sequencing [4]:
Alligator clip probes from First Electrical Connections with a Breadboard [5] and recently used in Measure Blinking Light with a Voltmeter [2]:
Jumper wires that connect the 3V to the (+) bus strips and GND to the (-) bus strips from Set Power for Circuits [6]:
3-pin headers from First Electrical Connections with a Breadboard [5] that connect the alligator clip probes to P2 and P0:
If you completed Measure Resistance [7], leave these Ohmmeter Circuit parts connected to your board too:
