Christoph Döberl tweaked a motor fader from a mixpanel to use it as an internet-connected light dimmer with lots of IoT magic.

To demonstrate the possibilities and make a cool project, we decided to build a light dimmer with the motor fader. The idea is to read the sensor in the fader and dim a smart light bulb accordingly. When adding multiple input interfaces each fader can be adjusted to represent the correct value by controlling the motor. The resistance sensor allows a stepless control for any brightness level, which comes in handy especially in the evening hours where a dimmed light can be particularly soothing.

An ESP32 is used to read the sensor and interface with the motor. It comes with a bunch of IO pins as well as Bluetooth and WLAN, so basically enough for this small project. The resistance sensor is read using ADC and the motor is controlled via a motor driver.

The Waveshare ESP32-H2-DEV-KIT-N4-M is a development board based on the ESP32-H2, available for only $6.65 on Aliexpress, but you’ll also find it on Amazon and Waveshare’s official store. This is a significant price drop compared to last year’s official Espressif ESP32-H2-DevKitM-1 board, which was priced at $10 without including shipping costs and with a similar design. In 2021, Espressif Systems introduced the ESP32-H2 to the world. However, it wasn’t until 2023 that they released their first development board. Since then, there haven’t been many products built around this new module. Some exceptions include the Olimex ESP32-H2-DevKit-LiPo, LILYGO T-Panel, and the ESP Thread Border Router/Zigbee Gateway board, all of which feature the ESP32-H2 chip. Waveshare ESP32-H2-DEV-KIT-N4-M specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh, and 802.15.4 (Zigbee/Thread/Matter) radios.

Brian Dorey documents building a remote controller for three Elgato Key Lights using a low-cost ESP32 WiFi module with push switches and indicator LEDs.

This project is an upgrade to the previous blog post where I created a simple remote-control switch to turn on and off a single WiFi-connected Elgato Key Light.

The lights do not have any buttons for manual control, and you need to either use the Elgato Control Center app on a mobile device or the desktop software to change the settings or turn the lights on and off.

The lights retain their previous light level and colour temperature settings, so a simple controller with three push buttons would be ideal to allow remote control without needing to use the mobile app or start the main PC every time we wanted to use the lights.

A 3D printed case encloses the project electronics. The code is written in Arduino.

The project is documented here and the code is on GitHub.

Waveshare has recently launched two new ESP32-S3 4G dev boards – the ESP32-S3-SIM7670G-4G and the ESP32-S3-A7670E-4G. These boards support 4G LTE Cat-1, Wi-Fi, Bluetooth, and GNSS, and come with an OV2640 camera, and a battery holder for a 18650 battery. The main difference between the two is that the A7670E module also supports 2G GSM/GPRS/EDGE at 900/1800MHz while the SIM7670G module does not. The board has two rows of I/Os including GPIO, I2C, SPI, ADC, and USB 2.0. It also has a USB-C port for power and programming, a slot for a MicroSD card, and an option to connect an external speaker. There’s a USB switching IC and DIP switch for easily connecting the module to a PC for internet or debugging. Waveshare ESP32-S3 4G Dev Boards Specification: Communication module A7670E 4G – A7670E Cat-1 4G module supporting 4G Cat-1 + 2G networking, GNSS positioning, telephone calls, and SMS. SIM7670G [...]
