Activation of relay is decided by pressing the push button or sensor readings (in this module sensors are replaced with another push buttons). To activate the relays, one must press the button ...

This project demonstrates how to create a 4-bit binary counter using an Arduino Uno. The counter increments with each press of a push button, and the binary count is displayed using LEDs. Connect a ...

In this Circuit, we are interfacing Joystick with Arduino simply by controlling four LEDs as per the movement of the Joystick. We have placed 4 LEDs in such a way that they represents the direction of ...

Figure 4 shows the Arduino-Nano board. The board drives an 8*2 LCD (LCD1) and also reads the status of the SW1, SW2, and SW3 push buttons. It also sends/receives the TEA5767 data through the I2C bus.

Arduino in Control. AR1, an Arduino Nano board (see Figure 4), is used to control this digital FM receiver. It drives a standard 8 x 2 character alphanumeric LCD (LCD1). It reads and reacts to the ...

GPD2846 MP3 Module: The heart of this mp3 player project is the GPD2846 MP3 Player Audio Decoder module. This module has a SD card slot in which we can insert an SD card with MP3 songs, and when we ...

It has two push-to-activate buttons. Inside (Figure 2) is an ESP32 module that drives the OLED display and a LoRa transceiver module. Note that the ESP32 module was only used for convenience, not for ...

Expansion Headers – Arduino UNO compatible Shield connectors (3.3V only!) with 23x GPIO lines, including 6x high-speed Sigma-delta ADC channels; Wireless Connectivity – Optional ESP8266 WiFi on PCB ...
