Automated water pump controller using Arduino UNO and DS1302 RTC module

Arduino UNO R3 with RTC module controls pump relay. Timer activates relay every hour for 40 s, irrespective of power outage.
ESP-01 WiFi relay controller via local network and with MIT Android app

Control relay using ESP-01 via self-hosted web page using IP address (can be configured as dynamic or static) in browser on local network and simultaneously via Android app built using MIT App Inventor (http://ai2.appinventor.mit.edu/).

ESP-01 WiFi LEDs controller using 4 GPIO pins

ESP-01 controls 4 LEDs independently via self-hosted web page using GPIO 0, 1 (TX), 2 and 3 (RX). Note: GPIO 2 should not be connected to LED at boot up but it can be set as INPUT to sensor.
Measure AC Current using ACS712 and ESP-01

ADC pin

Set timers to control 3 relays. Current sensor enables deactivation of pump if current thresholds exceeded.

Using Arduino UNO, DS1302 RTC module and ACS712 current sensor
Using NodeMCU v1.0 12-E, DS1302 RTC and ACS712 current sensor (web page configurable via NodeMCU WiFi Access Point)
