Working on my garden lights
Working 12V relay bottom left, and upper right the Raspberry $ compute module board with NodeRed.
I made a little board to program the ATTiny85.
The RS485 chip I wanted to use (SN65HVD3082) came as SMD, luckily I have some SMD to THT/DIL boards. (breakoff)
Above on the breadboard : The SN65HVD3082EP on a little pcb, the ATTiny85 .
4×4 WS2812 led matrix will be my dimmable RGB garden light.
