Hi,
I am supposed to add a two-digit seven segment display in my project. I am using PIC16F877a as my MCU. I only have 8 ports available. Now as I was searching through the net, I think I need a total of 14 ports for the two seven segment displays.
That's my problem, if my understanding is...
Hi guys,
I am planning to create a simple 10 second timer. I'm using C as my language.
I did read a little about timers but I didn't quite understand it so I tried to improvise. Below is the code I ended up with it didn't work out as planned. It did have a lot of flaws. But when I was...
Hi. I am planning to create a stopwatch using switches (to signal the start and end of the watch) and PIC16F877A. I plan to use C++ for my programming.
I have a question though, how fo I choose the oscillator? I mean, should I consider this since I want the timer to be like real time??

Re: Solenoid Valve
I was told to use LDRs and LEDs. Am I in the right direction?
The plan is once the LDR senses the light from the LED the solenoid valve will be activated. Im not really sure about the outputs yet because I'm still trying to figure it out.
Thanks
Hi,
This is my first post here and I hope I explain this correctly.
I am seeking to make a solenoid valve switch on and then off (for oil) after a given interval. It is AC powered, it will be activated by a light sensing circuit. I have been advised to look at relay circuits and driver...
