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.

In this article we will learn **how we can measure the individual cell voltage of the cells used in a Lithium battery pack** and will design a simple circuit using op-amps to measure the individual cell voltages and **display it on a LCD screen using Arduino**.

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
This is a custom - Arduino uno - based circuit.
- Microcontroller: Atmel ATMega328p
- Bluetooth Module: Support HC-06 & HC-05
- Motor Driver IC: Two L293D (up to 4 DC motors or up to 2 stepper motors)
- Servo motor header
- 3 input/output pins (Can be used to connect LEDs or button SWs)
- Programmable header
- Reset button

This my first take on an Arduino Nano PLC(ish) device.
It uses standard discrete components and thus is rather cheap to build.
But discrete components do take up a bit more space.
The inputs can accept up to 24v and are connected to the analoge pins, using optocouplers the inputs are electrically isolated
from the Arduino.
The outputs uses relays, the outputs from the relay uses an external sourc...
