Actually I had it half way done, I messed up when making the first schematic.
If I only click the switch then release it, the transistor stays on after about 2 seconds, but this is not what I want.
The switch will be always ON (removed from schematic), what I want is: As soon as I have power I...
Hey everyone :)
What I'm trying to do: As soon as we have power, run the relay for a few seconds (adjustable by changing the Capacitor if I'm not wrong)
Note I'm not very familiar with electronics so I'm probably making a huge mistake here!
The version that works:
As soon as I click the...
That is how it is done, schematics are not really correct, otherwise the PIC would not even be working.
LM35 is directly connected, what do you mean a 0.1uF from ADC input to ground?
Power supply is 12V 300mA, then it goes thro a Diode and then to a 5Vregulator.
The LM35 is connected...
PIC16F716 ADC With LM35CZ (Updated)
Hey Guys, I'm trying to read the temperature out of a LM35CZ, it outputs the amount of Celsius degrees in mV (Example 20Cº = 0.20V).
Here is the schematics, simulation in Proteus seems OK:
**broken link removed**
I'm using the following code, I'm using CCS...
Thank you all, very useful, replaced my 200ohm led resitor with a 1k one, also MCLR doesn't seem to do anything different whenever I use the 10k resistor, a 400ohm resistor or directly connected.. Then what do you mean with the high/low state?
Thanks once again!
I added a 200ohm resistor before the led not to burn it just now.
That worked like a charm!! Why?
Also, is the 10k resistor really needed between MCLR and VDD? Why?
Thanks, that was a great help!
I completely forgot to say that I already have two 25pF capacitors correctly attached to the circuit, otherwise I think it would not even work with the PIC628 right?
--Edit: Just noticed, sometimes I plug it to power and it runs for like 3~4 seconds, then stops.
Hey all, new here so please no flaming just because I'm newbie in what concerns to electronics, I'm just a programmer trying to learn.
16V -> Diode -> 5V Voltage regulator -> Pic VDD
4Mhz Oscillator I found from spare parts correctly connected to port 16/15
Led + to Port B2
Here is the code...
