Single Channel PS3 Wireless Remote ON/OFF Switch

The board presented here is multipurpose hardware which includes the ESP32-Wroom module, 3.3V regulator, 5V relay, Power LED, Relay LED, and connector to program the ESP-32 Module. The project requires 5V_DC and consumes 60mA current when the relay is ON. The project can be used in IoT applications and the relay can be controlled using Bluetooth or WiFi. The hardware helps users develop single-channel relay-based projects. The relay can be controlled over Wi-Fi, and Bluetooth wireless communication using appropriate code. The relay is connected to the GPIO4 pin of the ESP32 module.

Features

• Supply 5V_DC
• Load Current 60mA (When Relay is ON)
• Relay Contacts Normally Open and Normally Closed
• Relay Contacts Load Current Up to 10A
• On Board Power LED
• On Board Function LED
• Screw Terminal for Power Supply Input
• Screw Terminal for Relay Contacts
• On Board Connector to Upload the Code
• PCB Dimensions 62.87 x 36.20mm
• 4 x 3mm Mounting Holes

Relay ON/OFF switch using PS3 Wireless Remote

We have tested a simple on/off switch using this hardware and a PS3 wireless remote controller. The PS3 wireless remote works with Bluetooth thus it is easy to pair this board with PS3. Example code is available as a download. This code can be uploaded using Arduino IDE, follow the links below for more info about pairing the PS3 remote, and ESP32 programming.
