I have a test board wired to check ports. The Junebug is charlieplexed so its not real easy to just turn on one LED.
I want more control over the ports thus this test board.
just connect the LEDs to desired port pins etc.
very basic but it works.
I wanted to test a PWM project I am working on (LED candle flickering) using 3 LEDs.
on my test board I soldered a 5 pin header so I can connect the programming cable from the Junebug to my test board w/o pulling the PIC every time I want to change the code.
Hi MrDeb how are you?
I made a LED candle flickering with a 12f508 and some resistors to make a sine wave
You posted a link way back to how to do it that way so I tried it with some yellow leds
It worked better then you would think
I used PWM. Am assuming its different than the sine wave your talking about?
lets see, resistors = must be a ADC circuit??
I recall you were working on something using ADC??
I am trying to complete the project using the flickering candle but other things get in the way.
building a Lego table, a Theremin (grandparents revenge) for my 4 year old grandson)as well as preparing for the county Fair next weekend.
looking at schematic, the transistor turns on and all three leds turn on.
by varying the base voltage the transistor conducts less thus dimming the leds??
isn't this hard on the transistor (not saturated??)
maybe I is missing something??
I recall a circuit I was working on doing about the same thing but a slow transition.
also with a cds light sensing
wish I had knowen more about PICs before ordering all the parts.
still need to build it.
The kid I have been working with designing and hopfully build a spectrum analizer / graphic equalizer is headed to Idaho State Universcity come next week. His mom bought my second juney.
I added the cost of both then divided by 2 = $25 each
good deal for both.
will look at the adapter colin55 limked to??
I am new to PICs and I was wondering what would be the ideal microcontroller and module to program a motor. The microcontroller needs to fit in a 1.5cm diameter pin and consume very little power. I have searched around an the PIC 16F877A is my choice at the moment. Any suggestions???
Ok after searching around, I'm thinking the MICROCHIP - DV164121 - DEBUG KIT, EXPRESS, PICKIT2. Would that suit my needs?? Farnell are selling the kit for $100AUS, is that a good price??
Again, I am new to PIC microcontrollers and need to control a small motor. I also need a low power operating microcontroller.
Cheers
