operational amplifier - Analog PID controller (transferfunction questions)


I have to build an analog PID controller (with op-amps), I've made a schematic:


enter image description here


My questions:




  • Can I build my PID controller this way?

  • My PID tranferfunction (in the s-domain) looks like:


$$\text{H}(s)=\text{K}_{\text{r}}\left(1+\frac{1}{\tau_is}+\tau_{d}s\right)$$


But what in my schematic represents the variables from my transferfunction?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
