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

Hi @Vipin-I-V ,
This seems to be an interesting project.
Please share the development here...
I was thinking of something similar, but not for gaming. Won't it be cool to have the Ctrl, Cmd & Alt keys as pedals? Please share your thoughts & insights.
Hi @mkgrmAbhinand ,
Did your issue resolve?
@mkgrmabhinand Hi, It Looks like you didn't install the NodeJS on your computer, or didn't add the PATH correctly in the environment variables.
Could you confirm that you installed the Node JS in your computer from the .exe or .msi installation files?
If not and if you want to run Node-RED, you need to install recommended NodeJS version 14.x and you can download the version here .
Thanks for sharing @rafitc99 . Glad to know that it was solved.
