The weather is ok, but as a newbie in this BBS I feel some nervous for my posting, I'm scared of there will be some mistakes in my post, even though I have passed the forum rules.
I'm designing a PIC based timer circuit.Attached diagram is the circuit. 10K resister is the Preset value for analog input of the PIC micro.For the outputs I have only a MOC3042
(10mA) driven triac.
The problem is due to voltage drop of the bridge rectifier, the output voltage is limited to 4.5V. Which is affecting to internal analog reference as well.
How to solve this.I'm using PIC12F675
I added the load & checked the graph.It has a worst ripple.
I don't need much A/D resolution, need the analog in to be scale to 10 values.Except analog IN will this ripple affect to PIC functioning properly..
Thanks all guys.https://i.stack.imgur.com/6fRhy.png
