The TouchLed library lets you hook up an LED to your ESP32 and have it double as a touch button. More precisely ... Not even a resistor for 2-wire operation. And getting something working as a touch ...

It consists of two assignments: the first involves building a circuit with an Arduino UNO and a push button, while the second involves creating my own LED matrix (DIY version ). The digital pin 2 is ...

In this blog, we will learn how to create this fun 2 player ... LED_PIN, GRB>(leds, NUM_LEDS); pinMode(BUTTON_PIN1, INPUT_PULLUP); pinMode(BUTTON_PIN2, INPUT_PULLUP); pinMode(BUZZER_PIN, OUTPUT); } ...

The buttons are wired into a digital input pin and an analog ground pin. I’ve used pins 2 and 3, as you will be able to see in the code later on. Wiring up the LED matrix to the Arduino was a ...

Let it hit your red LED ... button presses would make it speed up even more. But there are really just the two speeds with the current programming. Inside the cool laser-cut box is an Arduino ...

Comparing I2C (Inter Integrated Circuits) in STM32F103C8 Blue Pill board with Arduino ... LED by using master STM32F103C8 push button value. These values are sent via I2C communication bus. The ...
