A single channel Programmable Logic Controller for hobby and light industrial applications. Based on the Atmega 328 microcontroller for full Arduino IDE compatibility. Board measures 2.79 x 1.5 inches
Status: Completed – prototype in process
Buy-It: Tiny PLC Solo
Features:
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.
Reason Developed: 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.
