// This robot is built to replace the 2017 Uno robot in the greenhouse //
// As outputs the following modules are mounted: //
// - Standard Arduino Onboard LED (PWM) //
// - 3 color LED (PWM) //
// - Activ loudspeaker //
// - 220 Vac Relay //
// As inputs the following modules are mounted: //
// - DS1307 Real Time Clock //
// - DHT22 air temperature and air humidity sensor //
// - LED //
// - CJMCU soil huidity sensor (TWI) //
// For communications are mounted: //
// - Standard Serial Monitor output //
// - ESP-01 Wifi unit //
// //
// Connect ESP-01 to your Arduino: //
// Yellow = Arduino RX1 19 = ESP-01 TX //
// Blue = Arduino TX1 18 = ESP-01 RX //
// Connect your Arduino to your PC and open the serial monitor. //
