Lab goals:

1. Get comfortable breadboarding
2. Learn how to read sensors (pushbutton & joystick) using the Serial Monitor
3. Visualize sensor output through Serial communication with Processing

Materials:

• ESP32 with headers soldered
• Breadboard
• Button
• 220 Ω resistor
• LED
• Joystick
• 5x Female / Male wires
• Jumper wire

Part 1: Button + Blink

Wire up your circuit as shown in the schematic above

• LED connected to Pin 15 via resistor (220Ω)
  • Ensure the shortest leg (anode) of LED is connected to ground - the direction of the LED matters since diodes only conduct current in one direction!

• Pushbutton connected to Pin 2 and ground
  • We don’t need a resistor with our pushbutton since we’ll use an internal pullup resistor
  • The legs of the pushbutton should straddle the middle of the breadboard
  • When the button is pressed, it will connect the ends as shown below (e.g. Pin 2 gets grounded)
