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

Hi team,
Any one have experience in Altium schematic designing.
I am facing some issue in Hierarchy->harness in Schematic.
The offpage number for harness is not showing, and while generation the smart PDF if we click the harness port /green box the page want to go there automatically, but that also not working. -
Hi @dipu_varghese ,
Here is the sample input from the binary edge impulse inference,
Predictions (DSP: 16 ms., Classification: 1 ms., Anomaly: 2 ms.): idle: 0.91016 snake: 0.08203 updown: 0.00391 wave: 0.00391 anomaly score: -0.067”And from here for example we can try to get the updown values only by attaching the device to another controller and read the Serial string directly.
void setup() { // Start serial communication at 9600 baud Serial.begin(9600); } void loop() { // Wait until there is data available on the serial port while (!Serial.available()) { // Do nothing } // Read the input string from the serial port String inputString = Serial.readStringUntil('\n'); // Find the position of the "updown" value in the input string int updownPos = inputString.indexOf("updown:"); // If the "updown" value was found in the input string if (updownPos >= 0) { // Extract the "updown" value from the input string String updownString = inputString.substring(updownPos + 8, inputString.indexOf('\n', updownPos)); // Convert the "updown" value to a float float updownValue = updownString.toFloat(); // Output the "updown" value Serial.println(updownValue); } }The sketch should then output the "updown" value, which is 0.08203.
Hope this will be helpful, let me know if you need more clarification.
