This controller was developed using Renesas SKP16C62P Starter Kit Plus. Each remote controller is controlled via RF. There are four types of generic control: general purpose timer, sprinkler timer, cooler, and heater. Each Controller may have up to 4 stations, (the Sprinkler Timer may have 8 outputs by multiplexing the outputs). Each controller’s program [...]

This DTMF controller is built based on PIC16F84A Microcontroller, MT8870 DTMF receiver, and an ULN2803A relay driver. The Controller has 8 OC outputs to drive 8 5/12V relays of any type. In addition to 8 OC outputs, header/terminal socket also provides 12V, Ground & 5V (for pull-ups only).

This low cost distributed motion controller system consists of two units: a USB-CAN converter and a dual axis controller. The USB-CAN converter uses the PIC18F258 and a FTDI FT245BM USB interface chip to translate messages between the USB and CAN buses. While PIC18F458-based dual axis controller is kept busy implementing servo/stepper trajectory and PID calculations [...]

This AVR Greenhouse Controller project consists of two units, transmitter with microcontroller a AVR ATmeg8535 as main processor and the receiver controlled by AVR AtTiny 2313. The transmitter unit is located in the greenhouse while the receiver placed in the house about 75 feet from the greenhouse.
