First Steps

Hardware

• Metro ESP32-S2 MCU

Setting up IDE + Board

• Launch Arduino IDE V2.3.4
• Install board driver
• Connect board to computer via USB + Install boot loader so the board accepts program upload from the computer
• Select board in the IDE
• Compile & upload an empty program to ensure all is ok

Digital Output + Setup Function

Write a program that turns ON the builtin LED Use setup() function alone

LED ON/OFF

Write a program that turns ON the builtin LED, then turn it OFF. Use setup() function alone

• What issue do you observe?
• How to address the issue?

LED ON/OFF with Delay

Write a program that turns ON the LED, wait for 1 second then turn it OFF Use setup() function alone.

Repeated Blinking

Write a program that blinks the builtin LED repeatedly and forever.

Integer Variable + if

Write a program that makes the builtin LED blinks faster, i.e. minimize delay.

• Start with a delay of 1000,
• Decrement by steps of 50,
• Upon reaching 0ms restart with the maximum delay
