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

Recently, I got a chance to work work the SeeedStudio T1000 tracker and I made a tracker and data logger with it. It comes with a LoRa module to transmit the data and has an inbuilt temperature and light sensor. The device is very easy to set up and get-started and I can say the experience of switching from different LoRa network servers is very pleasant and straightforward, same for the integration. I chose Ubidots to visualise the data captured.
I also like the mobile application very much, it’s so easy to pair and change the tracker configuration on the go. I love it.
I will experiment more and share my insights here. let me know if you want to know any specific details about the SenseCAP T1000.
It’s live on Kickstarter and you can pledge for $29 for single T1000 tracker, you will get 1 piece T1000 with 3 months of free trial service on the SenseCAP platform. Take a look : https://www.kickstarter.com/projects/seeed/sensecap-t1000-track-what-you-care-with-no-boundaries

@dipu_varghese Hi, How does it go? Would like to know about the updates
or anything I can do to help you. -
@zainmuhammed Oh that's cool. Let me also take a look at the stability analysis of a drone and get back to you.

@salmanfaris I'm building a payload-releasing drone under 2kg (micro class). and the entire structure builds using carbon fiber and ABS plastic.
