This blinky project shows how to interface LED to the ESP32 and write a simple program to make the LED blink. The full code is on Github, click here. Parts List ESP-WROOM-32 module USB<->TTL converter (3.3.V) Efficient power supply (3.3V) R1 – resistor 560Ω, see LED Resistor Calculator LED1 – basic LED Circuit Diagram Firmware … Read more
This Project simply flashes the LED in random manner. It uses PRNG (Pseudo Random Number Generator) based on LFSR (Linear Feedback Shift Register) to generate 16-bit (pseudo) random numbers. The less significant bit of randomly generated number is a major factor in decision to on/off the LED. The code is on Github, click here See … Read more
This project shows how to simply Fade-In and Fade-Out a LED by using delay function to control pulse width what is sometimes called Software PWM (Pulse Width Modulation). In our circuit a LED is connected to PB0 and it is made to Fade the LED In and Out alternately. The code is on Github, click … Read more
