ESP32 Training in Mohali

ESP32 training in Mohali is the natural next step after Arduino basics. The ESP32 combines a dual-core 32-bit processor, Wi-Fi and Bluetooth in one low-cost module, which is why it appears in so many student and commercial IoT builds. This course at Brain Birds Technologies teaches you to use it properly rather than only copy sample code.

What makes the ESP32 worth learning

Compared with an Uno, the ESP32 has far more memory, faster clocks, multiple ADC channels, touch pins, hardware PWM, several UARTs and dedicated I2C and SPI peripherals. It also brings real wireless connectivity, so you can send sensor data to a broker or phone without extra modules. The trade-off is more complexity: voltage is 3.3 V, pins have special boot functions, and power draw needs planning.

Course content

• Board and module anatomy: DevKit pinout, strapping pins, ADC2 and Wi-Fi conflict, flash and boot modes
• Development options: Arduino core in the Arduino IDE or PlatformIO, with an introduction to ESP-IDF concepts
• GPIO, touch sensing, PWM through LEDC and the 12-bit ADC with calibration
• Wi-Fi: station and access-point modes, reconnection logic and captive-portal style provisioning
• Web: an on-board web server, HTTP requests to REST APIs and JSON parsing with ArduinoJson
• MQTT: publish and subscribe, topics, QoS and retained messages with brokers such as Mosquitto or HiveMQ
• Bluetooth: classic serial and BLE services, characteristics and notifications
• FreeRTOS on ESP32: tasks pinned to cores, queues and mutexes
• Low power: deep sleep, wake-up sources and a realistic battery estimate
• Over-the-air updates and storing settings in NVS or SPIFFS
• Sensor integration with DHT22, BME280, MPU6050 and OLED displays

Hands-on builds

Examples include a Wi-Fi weather node that posts to a dashboard, a relay-based home controller operated from a phone, a BLE beacon scanner, an attendance device using an RFID reader and an air-quality monitor. For more ideas see IoT project ideas.

Fit with other courses

If you are new to boards, start with Arduino training and return here. Learners aiming for broader systems can join IoT training in Mohali, which places the ESP32 inside a full device-to-cloud pipeline.

Practical details

You will want a laptop, a USB data cable and a DevKit board. Whether boards and sensors are supplied is confirmed on enquiry, along with the software stack and cloud platforms used.

Outcome

You should be able to design a small connected device, write reliable networked firmware, secure basic credentials and demonstrate a live dashboard. Duration and schedule are shared on enquiry.
