Wirelessly control devices using DTMF tones and PIC microcontrollers—build real-world remote systems with confidence.
Want to control devices from your phone without Wi-Fi, apps, or complex setup?
This course unlocks a classic yet powerful wireless control method using DTMF (Dual Tone Multi-Frequency) signals—like the tones from your phone keypad. You’ll learn how to decode these signals and trigger devices through a PIC microcontroller, creating reliable, offline control systems perfect for security, automation, and rural projects.
If you want to build phone-controlled devices with minimal hardware and high reliability, this course is your key.
Why DTMF + PIC?
No Internet required—just a phone signal or call
Works remotely and reliably, even in low-signal areas
Easy to integrate with relays, motors, alarms, and automation systems
Ideal for use in remote gates, irrigation systems, and security devices
This course shows you how to:
Connect a DTMF decoder to a PIC microcontroller
Detect and decode keypress tones from any phone
Use embedded C to process and act on DTMF input
Build a working wireless device controller using phone input
What You’ll Learn
How DTMF works and how it’s used for control systems
Connecting and configuring a DTMF decoder (MT8870)
Writing embedded C to process tone inputs on a PIC microcontroller
Mapping tone inputs to specific actions (e.g., turning on LEDs, motors, alarms)
Building a complete phone-controlled relay or device switcher
Debugging DTMF communication and signal handling
Expanding the design for more channels or feedback
Projects You’ll Build
A phone-controlled electrical relay system
A secure remote switch that responds only to specific DTMF codes
A multi-output control board triggered via keypress sequences
A simple remote automation prototype for irrigation or gate systems

FAQ
Q: What phone do I need?
A: Any phone with a keypad that produces tone-based sound (DTMF) works—landline or mobile.
Q: Is this like Bluetooth or Wi-Fi control?
A: No—it’s audio-based wireless control using sound signals from phone calls, with no internet needed.
Q: Do I need a SIM module or GSM setup?
A: Optional—you can test with a direct audio line or expand with GSM for full remote control.
Q: Will I get a certificate?
A: Yes—a Certificate of Completion is awarded at the end of the course.
Q: Can this be used in rural or offline areas?
A: Absolutely! That’s one of the biggest strengths of DTMF control systems.
