Kickstart and Innovate your blinds control design As pictures tell more than long explanations, let me start with some screenshots as below jpg’s from our IoT Studio to get familiar with this Trinamic/AVR IoT Project: Trinamic’s TMC5161 + Microchip’s AVR-IoT WG + Digi-Key’s IoT Studio Template

PROJECT

We build on our previous LoRa IoT weather sensor to run for a year on 2x AAA batteries. We'll look at the AVR ATmega328p datasheet to determine which registers we need to use to put the microcontroller to sleep, and we'll calculate how long we need to sleep before sampling the sensor again.
