The TL783 is a variable three lead mains voltage regulator chip having an output range of 1.25 V to 125 V and a DMOS output transistor which is able to handle in excess of 700 mA current. High Voltage Specification It is specifically configured internally for working with high-voltage applications where ordinary bipolar voltage regulators […]
Converting Analogue to Digital (Analogue Read Serial) – Arduino Basics
In this Arduino basics I have explained the code implementation procedure wherein an external analogue signal is fed to the Arduino analogue input and translated or converted into a correspondingly proportionate digital readout. Here we employ a variable resistance in the form of a pot as the analogue signal source. Analog Read Serial In this […]
Monitoring State of a Switch (Digital Read Serial) – Arduino Basics
This Arduino basics discusses the method of implementing a code through which the ON or OFF state of an external push-button could be read or monitored within the Arduino. Digital Read Serial Here I have explained through an example how to monitor the state of a switch by performing serial communication across your Arduino and your PC via USB. In excess to your […]
