Development Board on BatSTEM Academy

L1: My first project

Fri, 07 Mar 2025 00:00:00 +0000

My first BatSTEM project

What you will learn in this lesson

In this lesson, we will cover:

Accessing the BatSTEM Cloud IDE programming interface.
Connecting the ESP32 development board to the computer.
Understanding the “setup” and “main loop” blocks.
Controlling the internal LED of the development board.

Prerequisites

Before starting, you need to know your login details for the BatSTEM Cloud IDE platform https://ide.batstem.io.

L3: The LED Diode (2)

Mon, 10 Mar 2025 00:00:00 +0000

The LED Diode (2)

What you will learn in this lesson

In this lesson, we will cover:

Controlling an external LED from the development board.
GPIO pins: What they are and what we can use them for.

Prerequisites

To follow this lesson, you should have already completed Lesson 1: My first project and Lesson 2: The LED diode, as we will combine concepts from both to learn how to control an external LED connected to our development board.

L4: Variable-brightness LED

Wed, 02 Apr 2025 00:00:00 +0000

Variable-brightness LED

What you will learn in this lesson

In this lesson, we will cover:

Controlling the brightness of an external LED from the development board.
PWM outputs: what they are and what they are used for.

Prerequisites

To follow this lesson, you should have already completed Lesson 1: My first project, Lesson 2: The LED diode and Lesson 3: The LED diode (2). In this lesson, we will use the same type of circuit as in the previous lesson, but we will learn to control the LED using more values than just on and off.

L5: The RGB LED

Wed, 02 Apr 2025 00:00:00 +0000

The RGB LED

What you will learn in this lesson

In this lesson, we will cover:

What an RGB LED is and how it works.
Additive colour mixing.
Controlling the LED’s colour and brightness from the development board.

Prerequisites

To follow this lesson, you should have already completed Lesson 1: My first project, Lesson 2: The LED diode, Lesson 3: The LED diode (2) and Lesson 4: Variable-brightness LED. In this lesson, we will use three outputs on the board to control the three colours of a single component.

L6: The serial port

Wed, 02 Apr 2025 00:00:00 +0000

The serial port

What you will learn in this lesson

In this lesson, we will cover:

What a serial communication port is.
How to use it to send information to the development board and receive information from it.
How to use it to monitor and debug our programs.
Using variables.

Prerequisites

To follow this lesson, you should have already completed Lesson 1: My first project, Lesson 2: The LED diode, Lesson 3: The LED diode (2), Lesson 4: Variable-brightness LED and Lesson 5: The RGB LED. In this lesson, we will not add a new electronic component: we will learn to communicate with the board from the computer.
