In this post the ESP32-Cam module will be used to operate a generic color LED strip using an IR LED. The actions of the ESP32-Cam module will be controlled using a MQTT broker and Node-Red. The Node-Red webUI will be provided to allow manual controls. Node-Red will also use scheduled nodes to control the lighting based on time of day.<\/p>\n

The LED strip in this post is an inexpensive RGBW LED strip. These power strips are not logically addressable. Addressable LEDs are typically found in higher end lighting systems, such as DMX. Instead these simple LED strips are controlled with an included IR remote keypad. There are different varieties of these types of IR controlled LED strips and they don’t appear to support a set standard of operation. Because of this, it is assumed that the remote IR encoding will need to be captured and replicated.<\/p>\n

More details about capturing and replicating IR controllable device codes can be found here, https:\/\/learn.adafruit.com\/ir-sensor<\/a>. The demonstrations in this post makes use of that work. Here is a photo of the RGBW Controller and IR remote keypad.<\/p>\n

\"\"<\/a><\/p>\n

Using the sample Raw_IR.ino code from Adafruit, with the following code removed from the printpulses subroutine, provided the decoded IR stream on the serial terminal.<\/p>\n

Serial.println(\"\\n\\r\\n\\rReceived: \\n\\rOFF \\tON\");\r\nfor (uint8_t i = 0; i < currentpulse; i++) {\r\n  Serial.print(pulses[i][0] * RESOLUTION, DEC);\r\n  Serial.print(\" usec, \");\r\n  Serial.print(pulses[i][1] * RESOLUTION, DEC);\r\n  Serial.println(\" usec\");\r\n}<\/pre>\n
This was done for each of the 40 buttons on the IR remote keypad. Each of these readings were gathered and collected into a spreadsheet to provide a visual of the IR streams. All of the buttons on the remote show a pattern using this approach.\u00a0 Each key is represented by colomns in the following figure.<\/p>\n
\"\"<\/a><\/p>\n
The first 35 rows show nothing discernible between each of the keys. This might be primer data to get the controller ready to receive the actual data.<\/p>\n
\"\"<\/a><\/p>\n
The differences start to show starting with the 36th rows through the 69th. It appears that these are 2 bytes for each key value.<\/p>\n
\"\"<\/a><\/p>\n
Diving into the details of how the key streams are structured wasn’t necessary for this work, but it did show how well the decoding method worked at capturing the streams. Ultimately, each of these captured readings were used in their entirety for the following code.<\/p>\n

This code was loaded on an Arduino Uno as a proof of concept. The serial terminal prompts for user input and executes its subroutine after being entered. This code became the basis of the final code installed on the ESP32-Cam later on in development. The Arduino Uno was fitted with an IR LED on Pin 13 and Ground. A resistor was placed in serial on the Pin 13 side. The RGBW controller’s IR sensor was placed close to the Uno’s IR LED.<\/p>\n
\"\"<\/a><\/p>\n
Once validated, this code was ported for use on the ESP32-Cam module. Other features such as WiFi and MQTT client support are included. Not all of the keys from the IR remote are programmed since this controller is strictly to mimic dawn, dusk, warm lighting, and mid day sunlight. This limited the keys needed to the following:<\/p>\n
White with on, off, brighten, and dim keys.
\nRed and Light Blue with on, off, brighten, and dim keys.<\/p>\n
This allows the LEDs to be adjusted along a wide color temperature range. See https:\/\/en.wikipedia.org\/wiki\/Color_temperature<\/a> for more detials regarding this topic. Here is the code used on the ESP32-Cam module.<\/p>\n

The IR LED used to act as the IR remote is attached to the ESP32-Cam module’s ground and GPIO 2 pin. A resister was placed in series between the IR LED and the GPIO 2 pin. The ESP32-Cam module was stacked on the RGBW Controller with the IR LED and IR Sensor mated.<\/p>\n

With the ESP32-Cam module powered on and joined to the network, Node-Red then becomes the process that controls the overall functions. The flows consist of several button nodes, each of which connect to a corisponding mqtt node. These button nodes appear on the WebUI and when pressed, publish to the MQTT Broker thier specific topic. The ESP32-Cam subscribes to these topics and enters in the subroutine that pertains to the topic. There are also light scheduler nodes that run at a defined time and will publish topics based on the mqtt node payload.<\/p>\n
Having the ability to automaticlly and remotely control simple RBBW LED strips using inexpensive hardware may seem trivial. However, IR control functions can be enhanced on other devices that may prove to be more valuable than what was demonstrated here.<\/p>\n","protected":false},"excerpt":{"rendered":"
In this post the ESP32-Cam module will be used to operate a generic color LED strip using an IR LED. The actions of the ESP32-Cam module will be controlled using a MQTT broker and Node-Red. The Node-Red webUI will be provided to allow manual controls. Node-Red will also use scheduled nodes to control the lighting based on time of day. The LED strip in this post is an inexpensive RGBW LED strip. These power strips are not logically addressable. Addressable…<\/p>\n
