Total: 95 pieces. The number 830 refers to the connection points on one breadboard. There are 30 resistors in total; the image does not specify the quantity of each resistance value.

Planned first exercises

We will progress gradually: a first LED, a button controlling an LED, reading a potentiometer, reading the DHT11 sensor and showing values on the OLED display. This is a plan for simple exercises, not a completed or verified course.

This inventory was transcribed from the supplied image of the purchased kit. The exact ESP32 board and OLED display models have not been established; their markings and connectors will be checked before wiring instructions are prepared.
