The ESP32-C5 is one of the more interesting newer ESP32 parts because it combines Wi-Fi 6 in 2.4 and 5 GHz, Bluetooth LE, Zigbee, and Thread on one chip, and the ESP32-C5-DevKitC-1 breaks out most available GPIOs on the side…
M5Stack has released the M5Paper Color ESP32S3 Dev Kit, a compact ESP32-S3 development board built around a 4-inch full-colour E Ink Spectra 6 display. Unlike a normal TFT or OLED display, this screen is designed for low-power visual applications where…
This example shows how to read touch coordinates from an STMPE610 resistive touch controller using I²C or SPI. The sketch detects touch events, reads X/Y/Z pressure data, and prints everything to Serial for debugging and calibration. The STMPE610 is a…
This example shows how to control 8 LEDs using the PCF8574 I²C GPIO expander with an ESP32. The sketch cycles through each LED by sinking current through the expander pins, demonstrating how the PCF8574 works and why wiring matters. The…
This example shows how to use the Adafruit nRF8001 Bluetooth Low Energy breakout in callback mode. The sketch starts advertising, reports connection events over Serial, receives incoming BLE UART data, prints it, and immediately echoes the same data back to…
This example is the classic Adafruit graphics demo for the GC9A01A round TFT display. It initializes the display over SPI, runs several drawing benchmarks, prints the timing results to Serial, and then keeps rotating a text demo so you can…
This beginner guide explains how to wire a pushbutton to an ESP32 and use it to control an LED. You’ll learn what digitalRead() returns, why pinMode() matters, and how to avoid the most common beginner issue: a floating input (random…
This beginner guide explains the famous Blink sketch line-by-line on an ESP32/Arduino board. You’ll learn what setup() and loop() do, how pinMode() works, what HIGH/LOW really mean, and why delay(1000) makes the LED blink once per second (plus fixes if…
If the ESP32-C3 was the reliable workhorse, the ESP32-C6 is what you pick in 2026 when the project touches Home Assistant, Matter, Thread, or Zigbee. Why? Because it’s one of Espressif’s first “triple-radio” parts that puts Wi-Fi 6 (2.4 GHz…
If ESP8266 was the pioneer and the original ESP32 was the heavyweight champ, ESP32-C3 is the modern workhorse: Espressif’s first big move to RISC-V, built to be an affordable, power-efficient “drop-in upgrade” class for Wi-Fi IoT — but with Bluetooth…
