What is it?

A single channel Programmable Logic Controller for hobby and light industrial applications. Based on the Atmega 328 microcontroller for full Arduino IDE compatibility.

• Atmel Atmega328P-PU Microprocessor
• Arduino IDE compatible
• 6 pin ISP header for programming
• 4 amp rating -limited by trace thickness and width on PCB
• Relay is rated for 10A.
• Features an input header connected to an Analog pin on the chip. This increases versatility for custom applications.

Why did you make it?

I needed a way to economize the use of my water recirculating pump while ensuring I had hot water in the house. I designed and built this circuit to run for 75 seconds and then wait for 450 seconds. I wanted to be sure I could modify it in the future if the need arose.

What makes it special?

It is designed for easy hand assembly and to be easy to modify.

Kit includes all parts required for assembly.
