I need a compact, reliable controller that can switch an AC motor ON and OFF and let me set timing schedules from a smartphone over Bluetooth. The wireless link is the only command channel I expect to use—no analog or hard-wired digital inputs—so please choose components and firmware that make a stable Bluetooth connection simple for an everyday user. Key points to cover • Motor type: single-phase AC, 220 V supply. • Functions: instant ON/OFF plus programmable countdown and recurring timers. No speed or torque regulation is required. • Control method: Bluetooth LE connection to an Android / iOS app (a basic demo app or clear API documentation is fine). Deliverables 1. Schematic and BOM for the controller board, including protective circuitry for the AC load and an onboard Bluetooth module. 2. Firmware source code with commented functions for pairing, command parsing, and relay drive. 3. A simple mobile app or example code that sends the required commands. 4. Assembly, wiring, and safety instructions so I can reproduce the build and pass local electrical inspection. 5. A short test video that shows the motor being started, stopped, and run on a timer from the phone. I will validate the project by flashing the code, pairing a phone, and observing at least three consecutive timer cycles without communication dropouts or missed activations.

Triac or relay for the 220V motor — that determines the whole protection circuit: an inductive load needs a snubber and MOV, otherwise the triac may not turn off. Inductive load and galvanic isolation cost money, so $16 won't be enough for the board, firmware, and documentation together. What's the motor's power in watts? My closest relevant experience: microcontroller firmware — sensors, drive control, C/C++ (including RP2040).

My team and I can develop the Bluetooth-controlled AC motor controller around your requirements, including a properly isolated relay/contactor drive, BLE communication, instant ON/OFF commands, countdown timers, and recurring schedules. We’ll provide the schematic, BOM, firmware source with clear pairing/command-parsing/relay-control functions, and a simple Android/iOS demo app or documented command API. We’ll also include appropriate AC-load protection and isolation, assembly/wiring guidance, configuration instructions, and a test video demonstrating manual control and multiple timer cycles. The firmware will be designed to maintain reliable BLE communication and recover safely from connection interruptions rather than leaving the motor in an undefined state. For a 220 V mains application, safety and local electrical requirements will be treated as a priority, with appropriate isolation and protection rather than exposing low-voltage circuitry directly to the AC load. My team and I can handle the complete development and provide long-term support after delivery.
