I'm having trouble with the circuit I'm building here. It works on solderless breadboard. Not so much on the finalized protoboard I am trying to make.
picture of actual circuit
picture of back. Forgive the sloppiness.
Operation: arduino pinx is set to high and that flows to the LL transistor allowing for current to flow through and power the voltage booster which in turn powers the device. Unfortunately it doesn't seem to work on this board.
I tested the voltage booster itself by touching leads from the power supply directly to the inputs. Its led lit up properly which it did not do in normal operation of the protoboard but not enough to power the device. In the breadboard the led of the booster lit up and the booster powered the device.
THe power supply properly lights up an led and I've used it to power the arduino.
I measured the resistance between all teh connections save the ones through the transistor itself. All were near 0 or the value of the resistor in between.
I measured voltage via plugging in the multimeter into the positive input and touching the other lead to various points and I found a voltage of 8.75 throughout. Input source is actually 7.5 volts approx not 9V in the figure.
I tried measuring current. for the pinx to transistor wire there was a definite signal from the arduino but it seemed extremely low. The led I put in lit up very dimly. When I tried to measure it I only got brief pulses of .001 on the 2m and 0.1 on the 200u current settings. When I measured the current across the negative input wire there was no current I could detect.
Is there any problem you can figure from this information? Is there any further tests I can do if its still not clear what the problem is?
