Hello all, first sorry for my english, I try
Many tnx to Michael and Ranjib for all info and pi
I Finnaly recived hat 2 and ph probe..
Tomorrow I will print enclosure from thingsuniverse..
ok first thing first.. pi 3.0 is running on zero, and I have test connected temp and ph.. both are working ok. I have problem with connecting i2c relay board ( 16 ch) for controlling it with pwm 9685 chip. I chosen jack j1 pin 13,14 and 9865 driver under drivers and under lights pin 13,14 with same 9865 driver.
Then I tried to add multiple channels (4 for test) under light section on same pins 13, 14. As I understand it 0 is off or 100 is on, but nothing happens..
so pins 13,14 goes to sda, sdl on relay board. Power to relay board is supplied from power source, relay is powered but channels wont turn on, I have them all set on 100. I am missing something?
