Iam trying to draw rpm realtime graph in c#, but I have strange line drop sometimes. I just noticed it happens when I spin it high and i little bit drop rpm, then it shows like huge drop Can someone c# guru check if this programm error or picaxe ? main: count B.3,1000, w1 sertxd(#w1) goto...

Iam sniffing volts from battery and want to switch relay when volt ar >x or <x. What is best way to simulate,test this, like if volt > 571 then high one relay, if volt < 545 then high other relay, need your advice what is the simplest way to simulate this, whether you can send a command via the...

Relay is working,switching from 12v. Diode for protection is in place. Mosfet is switching when i apply 5v to gate diretictly from my power source, but it doesnt take output pin high 5v. It seems like its not right value, or to small current?

Iam trying to turn on relay (leg-12 , 12v). What is the best way to do this? Tried with mosfet irfz44n and 100r resistor , but its aint working (mosfet is not switching). What is the problem and why I can turn it(mosfet after which and relay is switching like it should) from 5v source but not...

1)I will use dc motor as generator, and I want to know how much V its producing. Can I use this methode? 2)If yes, what power rating resistors,zener diode, cap farad should I use for 24V 28W motor, it will be rotated to produce about 2 to 12V. If I cant use my schematic,please explaine...

My chip

I still need your help. MCP2200 ivertion didnt give 0-5v drop on green led test. It is 0+-, doesnt matter on or off So I tried again to make circuit with inverter, like this New caps that i used was 0.68uF (on pic are 10uF). Got 0-5v drop on port test(green led), but actualy it was 1-2 off to...

Did I connect correctly? Without invert check box i got 5v on green led off and <0 on on, when invert on - the voltage is aroud 0+-. i have big multimeter so i cant measure mv. Idont have 100nF at the moment, tried 10nF on pic and 10uF, nothing... Is exactly 100nF necessarily? Protoboard...

In conclusion, you can programm picaxe with MCP2200 , but be sure it is latest revision chip. Iam trying to use this http://web.argus.lv/shop/download/436689/hwindex.htm to communicate with my 18m2. This is mcp2200 chip based converter. Connected like told in tutorial with 10k 22k...

What is the best way to measure DC motor RPM, I will spin it to produce voltage. I dont know much about the motor, its 24v and 25w This is my first post and certainly not the last. Explain please in detail so I dont have to bother you again, I'm new to this micro thing :-)
