Turn power on and off to ultrasonic sensor (HC-SR04) » I have a project that runs on batteries and uses an ultrasonic sensor (HC-SR04). Every 15 minutes it takes one reading from that sensor. I would like to lower the power needed by turning off the power to the sensor for the time when it wasn’ t needed. Is that possible? Right now the power is attached to the +5 on the Uno. Can power to that pin be turned off? (The HC-SR04 is the only thing using it.) Can I move the power wire to another pin that I turn on when I need it and off when I am done?… Forum.arduino.cc

Power meter with LCD 20x4 + HC-05 BT readings - HEELP » Hello Inventor funs! I'm trying to built a power meter with Arduino Uno (using ZMPT101B/voltage + ACS712/current sensors). My sketch seems to work fine and i get the appropriate results on the LCD (after calibration). I calculate the Vrms, Irms, total power & real time cost and then i print the measurements on my LCD. My problem is that….i can't built the appropriate app in MIT Inventor !! I follow some "ready to go" examples with no result !! I want to send the total power and the real time… Community.appinventor.mit.edu
