Circuit Diagram: The complete Arduino Piano Project can be built on top of a breadboard with some connecting wires. The circuit diagram made using fritzing that shows the breadboard view of the ...

This one is based on a laser module, that constantly sends beams to the light sensor, and when someone/something passes, the sensor won't receive the beams, and the alarm is triggered, and won't stop ...

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 ...

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 ...

The proposed 28pin DIL module includes a surface-mount ATmega328, plus an Espressif ESP8285 for the Wi-Fi interface, a Wi-Fi antenna and 2Mbyte of flash memory. An integrated push button and ...

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 ...
