I will program your arduino esp32 with embedded c for iot sensors
About this Gig
Struggling to get your Arduino or ESP32 project working?
Not sure how to interface a sensor, drive a display,
or send data over WiFi?
I will write clean, well-commented embedded C/C++ firmware
for your Arduino or ESP32 project tested and working.
WHAT I CAN BUILD FOR YOU:
Sensor interfacing: DHT11/22 (temp/humidity),
HC-SR04 (ultrasonic), PIR (motion), LDR (light),
soil moisture, IR, flame sensors
Displays: 16x2 LCD (I2C), OLED (SSD1306)
Communication: UART serial, I2C, SPI
ESP32 WiFi: send sensor data to ThingSpeak or serial
Logic: threshold alerts, LED control, buzzer alarm
Data logging via serial monitor
WHAT YOU GET:
Clean .ino source file (Arduino IDE ready)
Well-commented code explaining every section
Wokwi simulation link so you can see it working
before uploading to your hardware
(Premium) Loom video walkthrough of the code

FAQ
Do I need the actual hardware to test the code?
No — I test all code in Wokwi, a free online Arduino/ESP32 simulator. I will send you the simulation link so you can verify it works before uploading to your real hardware.
Which Arduino boards do you support?
Arduino Uno, Nano, Mega, and ESP32. Message me if you have a different board — I will confirm compatibility.
Can you help me upload the code to my board?
Yes — I will guide you through the Arduino IDE setup and upload process via messages if needed. No extra charge for this.
Can you add WiFi/Bluetooth to my project?
Yes, but this requires ESP32 (not Arduino Uno). Send me your project requirements and I will confirm feasibility and pricing.
Can I see a sample of your work before ordering?
Yes — here is a live Arduino temperature monitor I built: https://wokwi.com/projects/461195538720689153 . You can run it directly in your browser.
