“This project is based on a 20X2 PICAXE Microcontroller. It uses a programmable timing circuit to allow the user to program repeated automatic plant watering cycles by controlling a small electric pump that feeds the plant water with 1/4 …
Content for PICAXE-20X2
The smallest PICAXE microcontroller in the enhanced X2 range. Very popular in hobbyist projects due to its compact size and powerful features, but also suitable for more advanced educational use. Capable and powerful! This chip supports up to 18 inputs/outputs with 11 analogue/touch sensor channels and an operating speed up to 64MHz using an internal oscillator. This chip has a single internal program slot, supports up to 32 external program slots and is capable of acting as an i2c slave device. All X2 series parts support enhanced features such as configurable i/o pins, ring tone music and touch sensor inputs, i2c, spi and high-speed serial with background receive. Scratchpad memory plus separate Data EEPROM and Data Table are supported.
