Norwoodd 2 Posted December 12, 2019 Share Posted December 12, 2019 The goal of this project is to utilize an MSP430 to allow existing remote-controlled outlets to by controlled over Wi-Fi. As purchased, the outlets can be controlled with a provided remote control which uses 434 MHz radio signals. By programing the MSP430 to replicate the signals from this remote and hosting a web page with controls on the MSP430, the outlets can be able to be controlled from anywhere on the same Wi-Fi network. The completed project provides a web page that can both control each of three outlets individually or all three at once. This is done using an MSP430 as a controller with a 434MHz transmitter sending commands to the outlets, and an ESP 8266 Wi-Fi module connecting to the network. A schematic of the completed project is shown in Fig. 1, and a photo of the completed project is shown in Fig. 2. With this set up the outlets can be reliably controlled from anywhere on the same Wi-Fi network. The components required for this project, along with the equipment necessary are listed below. All the components can be purchased for less than $30. I was able to write an interface to control the outlets, as well as serve a webpage to control the outlets. This was the final project for my Embedded Systems class at John Brown University. more details are avalible in the attached file.
