Optimize ESP32 Telegram Motor Control
Budget: $10 – $30 USD
I already have an ESP32 dev board toggling a 2-channel, low-level-trigger 5 V relay through a Telegram bot. The basic sketch is functional, but I want it tightened up, documented, and extended so the bot can reliably:
• start or stop the motor
• report current motor status on request
No alert system is needed at this stage, though the structure should stay flexible enough to add one later.
Your job is three-fold. First, review my existing Arduino (C++) code, eliminate redundant logic, improve readability, and make sure the asynchronous Telegram calls never block the Wi-Fi loop. Second, produce a clear wiring guide that shows exactly how the ESP32’s 3.3 V GPIO is shifted through the logic-level converter before it reaches the relay module. I would like this in two formats—an annotated schematic (Fritzing, KiCad, or similar) and a set of step-by-step photos I can mirror on my bench. Finally, walk me through the assembly and first power-up test over chat or a brief video call so we can confirm the relays click and the bot commands respond in real time.
Deliverables I will sign off on:
1. Optimized, fully commented .ino file that compiles cleanly for ESP32.
2. PDF/PNG schematic plus a photo sequence showing each connection.
3. A live call (≈30 min) during which we upload the code and verify /start, /stop, and /status commands work without false triggers.
If this fits your ESP32 and Telegram expertise, let’s set milestones and get the motor turning.
