NODERED and MCP23008 8-Channel Digital Input with I2C Interface

Very pleased with the performance of this board. It is attached to a Raspberry Pi 4B. I have 8 other i2c devices attached to the same bus.

I am using this board to monitor 8 level switches in two different vessels to control valves and pumps in Node Red. The Level switches are attached to this board… and the valves and pumps are controlled by another NCD product, the 8 channel MCP23008 Relay board.over i2c. Naturally, I am using .56uF capacitors to suppress induction.

Have many more devices to hook-up, but just wanted illustrate the devices working together in NodeRED.
