DTMF SHIELD
DTMF shield for Arduino. Enables remote control via phone keypad tones for automation and security projects.
Description
The DTMF Shield is a communication and control expansion board designed for Arduino and microcontroller-based projects that require Dual Tone Multi Frequency (DTMF) signal decoding. It enables devices to be remotely controlled via phone calls or GSM modules by interpreting keypad tones. Commonly used in remote switching, home automation, security systems, and industrial control, the DTMF Shield offers reliable decoding and easy integration. Its shield form factor allows quick plug-and-play connection with Arduino boards, making it ideal for students, hobbyists, and DIY automation projects.
