The LM555 generates an electronic horn signal which is amplified by an LM386. The tone and gain of the horn can be easily varied. The horn can be used in a car, scooter, cycle, and motorbike.
Infrared Sensor Module has built-in IR transmitter and IR receiver that sends out IR rays and looks for reflected IR rays to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.
It is Arduino and Rasberry Pi compatible b...

4 230 V inputs to monitor togle relais. Let you know if light is on or off and togle them witha domestic automationsystem.
Tested on Arduino and ESP32 board. May install a cap to filter 50/100 Hz or do it by soft (20 mS timer for on/of)
A 1-wire variant will be comming soon.

Test print for the Aruino (and mega)
Every output pin has an LED, and has a switch to 5V to test if it still works (and is not broken)
and the analog pins can be attached to a 0-5V rail to test there functions too
