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.
