Smart Switch Demo

Tap application → relay clicks → OLED updates.

Button is instant. App takes a network round trip. That gap isn't lag, it's architecture.

Wi-Fi off, button still works. That's where the logic lives.

@kevinlysocial This is massive, keep it up Engineer and do you have a Demo illustrating it basic operation?

@andykmakes (Note: Defaulting to OFF is the industry standard for mains switches because you don't want a fan or appliance suddenly turning on while you are away).

Built an ESP32 Smart Switch:
⦾ Relay
⦾ Buck converter
⦾ OLED
⦾ Push button
⦾ Socket outlet.

The relay is the safety-critical part it's the only component touching mains. Everything else is 3.3V. Phase 1 of 4. Open to IoT roles. #ESP32 #iot #TechHiveLabs #microcontroller

@andykmakes Great question. Currently, it defaults to OFF on power restoration for safety reasons. I'm planning to add NVS (Non-Volatile Storage) in Phase 2 so it can optionally remember the last state, depending on user preference.

@KritishBuilds Thanks for the tips! I'll check the relay datasheet and widen the mains traces for 10A. Mostly resistive loads for now.

@heygrexbot Appreciate that! Safety first when dealing with mains. Phase 2 will focus on opto-isolation and snubber protection."

Finished my ESP32 Smart Switch. The interesting part is the interface.

OLED shows LOAD, SCHEDULE, UPTIME. Button for override. Labelled input/output.

Why? Networks fail. State you can't see is state you can't trust.

The IoT SMART VEHICLE TRACKER is now packaged and deployment-ready.

LIVE TELEMETRY: GPS Fix, satellites, speed, altitude, coordinates, location, status. Live location transmitted to open-source map with visible road and terrain context.

Debugging the vehicle tracker has been a journey.

ESP32 + NEO-6M GPS + SIM900A + TFT Display.

Added WiFi. ESP32 connects. Added serial GPS works. Data flows. TFT just needs right formatting.

Hardware engineering is 10% building, 90% debugging. And I'm here for it.

My RFID attendance system is now fully packaged and deployment ready.
Functionality: 3 registered cards log IN/OUT seamlessly. Spreadsheet updates in real-time. Admin app handles enroll, delete, rename.

[James Peter Smart @smartplus_media]

Fully functional.

Walkthrough of my RFID attendance logger:

· ESP32 + RC522 + OLED + LEDs + RTC + power management
· 2 registered cards = IN/OUT logged
· 1 unregistered card = DENIED
· Admin app: enroll, delete, rename

#RFID #ESP32 #IoT #HardwarePrototype #EmbeddedSystems

Hardware: Microcontroller, RTC, OLED, RC522, LEDs all inside a clean casing with power switch and charging port
Mobile Admin App:
· Enroll new student
· Delete or rename student
�� Real-time IN/OUT status dashboard

WiFi connected. IP displayed. Database logging live. 2 cards get the green led while 1 get red

If you're building access control, never skip the "Denied" test. That single buzzer sound saves your entire database from corruption.

Building an RFID Attendance System (Part 1: Hardware & Logic)
Extracting UIDs: Every RFID card has a unique fingerprint. We read this to create a "white list
Ready -> Login -> Logout -> Unknown -> Denied. It’s basic, but it's the logic of life.
