This timer is useful in both domestic and industrial applications. It is a countdown timer programmable in the range of 1s …. 9999s. During this time, the load is powered by a relay on the board. For repeated timings, it is possible to memorize the timing duration (MEM LED on). The end of the period […]
In Today’s Tutorial, we will learn how to make our plant talk using Arduino nano with the MP3 player module. Basically, we will connect 3 sensors to the Arduino module: LDR Sensor. Capacitive Moisture sensor. DHT22 Temperature and humidity sensor. We will read the sensors values in Arduino and define the limits for each sensor […]
