Hi folks,
I have some 1W 8mm leds. At 2.1V they draw 300mA.
I have them controlled via a PIC thru a ULN2803 Darlington driver.
The circuit is powered by 3 x c batteries 4.5V. I measured the voltage from the ULN2803 chip at 3.9 volts as I understood a drop is normal.
I had calculated that to...
Hi folks,
I am a novice and hoping someone can give some advice on a circuit I am trying to build.
I have a circuit where I was using a 20M2 picaxe to decide which of two signals arrived at the inputs first. The program employed a couple of simple IF statements in a loop and lit some...
Hi follks,
In Logicator for PIC.
I want to design a flowchart, that will execute a command for 5 seconds to monitor an anologue pin to see if it goes over a theshold.
The duration that the signal will be over threshold will be short.
I can't see any timing functions. Other than wait.
But if...
