In this blog post, you will learn how to use the ACS712 current sensor with an Arduino to measure DC and AC currents. By the end of this tutorial, you will have a clear understanding of how the ACS712 sensor works, how to connect it to an Arduino, and how to read and display curr...
Arduino Current Sensor This Arduino based current, voltage, and power sensor/meter tutorial was created for hacktronics by Steve Spence. For my off-grid Ham Radio and Solar projects, I needed a way to measure volts, amps, watts, amp hours and watt hours. There's a couple of commercial pr...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
init(); // align sensor and start FOC motor.initFOC(); // add target command T command.add('T', doTarget, "target current"); Serial.println(F("Motor ready.")); Serial.println(F("Set the target current using serial terminal:")); _delay(1000); } void loop() { // main FOC ...

You can also move the second line of code to the ‘loop’ function so that it will be executed repeatedly and keep transmitting it. This is useful if you are monitoring something in real time such as voltage or a sensor reading.You should see the ‘TX’ light on your Arduino blink ...
