Recently, I built my first home automation system for outdoor garden lighting using the Tasmota open source firmware in addition to finished consumer relay switches from Sonoff and Shelly. As I started working with Tasmota, it became evident that the firmware was very flexible for many use case applications.

Tasmota works with ESP8266 and ESP32 microprocessors and comes with many features which include not only a web interface and MQTT client interfaces but also common standalone functions such as:

• Timers
• custom pin mapping
• configurable component behavior
• rules (scripting)
• support for a wide variety of sensors, buttons, relays, LEDs.

Is it possible to build cool electronic devices without having to write any Arduino code? The answer is YES!

This is a reference design for the Learning TasmotaPCB based on a Wemos D1 mini. It allows new Tasmota users to learn how to configure the firmware for various use cases. The PCB is configured with the following devices:

• two momentary push buttons on D1 and D3
• 4 addressable LEDs on D5-8
• a beeper/buzzer on D2
• LDR light sensor hooked through the single analogue pin with a voltage divider for 0-3.3v.
• A Maxim DS18S20/DS18B20 temperature sensor

I hope that you find this useful for learning the Tasmota open source firmware and implementing simple devices such a light/temperature sensors and connected LEDs and switches.

Learn, Master Apply!
