I'm looking for a 3D printer upgrade and came across this Arduino Relay Module. It's a 5V, 4-channel relay that can be used to control various devices with a simple switch or button press. The module is designed to work with microcontrollers like Arduino, PIC, ARM, DSP, AVR, and MSP430. I've also found the HC-05 Bluetooth Serial Transceiver Module which can be used to connect my Android device to the relay module via Bluetooth. This will allow me to control the devices remotely using my phone or tablet. The module is a slave and master transceiver that supports serial communication over Bluetooth 2.0 + EDR.
