Problem with power supply
-
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

@zainmuhammed Can try capturing the GPS when the device is starting the loop instead after joining the LoRaWAN and see?
You can put the GPS value on top of the loop or setup function.
Also, what kind of gateway are you using? Is it configured okay, OTA is done?

@salmanfaris Today I tried after connecting a 18650 cell,
Data getting in console after integration of both lora and gps.
here you can see that GPS value is 0,0. also in my previous post you can see that GPS value is not reading.
Also the status LED is active after it is connected to the satellite. -
Hi @zainmuhammed ,
Can you share the GPS and LoRa output when it’s working?
Also can try capturing the GPS when the device is starting the loop instead after joining the LoRaWAN and see?
Also make sure the device provides have enough to modules. The GPS need more power when you cold start.
