Problem with power supply
Geethesh last edited by salmanfaris
The above image shows the ckt with ultrasonic sensor and attiny 45 Ic ,Bd 140 transistor (for switching the 6v pump).
***The problem is when I give power from 5v regulator to all this as shown in fig, the circuit is not working ,(not enough power ).
What should I do.
Should I give separate power to motor
I am using 5.5v adaptor 500mAh.
*I have checked the circuit by connection separate 5 v from arduino ,to that attiny 45 ic and sensor,. Then it is working .
- Please help

@Geethesh The problem is here. There is huge voltage drop at some point of the circuit(probably at the pump or sensor, you should find it by probing at those particular areas) such that the voltage is getting attenuated by the time it reaches the Attiny. So, Attiny is working only when a dedicated supply is given to it. You can try this out by having multimeter probed between the VCC and GND of the ATTiny45. Try having a stable supply to Attiny

Developing Android Applications with Eclipse is a bit old way. Few eclipse enthusiasts might be doing it still though. For your issue, check all the environment variables related to SDK and Emulators are correctly configured.
If you're a beginner and no specific reason to use Eclipse, try to start with AndroidStudio.
@rahuleapen Can you please share the connection diagram?
Arduino has been compiled to run a motor pump. The pump seems to be working fine via the 5v and ground port with appropriate voltage and current. The same voltage and current is seen across the gpio whenever turned high but the motor doesn't run via gpio. Can anyone help me out here..please it's urgent
@rosetoby Thanks for sharing, can you post your queries with details, code snippet ..etc
@vipin-i-v I think so, let us know the updates!
