Make an Arduino Temperature Sensor (Thermistor Tutorial)

There is a switch and a resistor (Europeans use a rectangle instead of a squiggly for resistors), they are both connected to a pin on the Arduino microcontroller called RESET (in the bottom right corner)

New library to read Arduino VCC supply level without

The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected

Measuring DC Voltage using Arduino. Created on: 23 May 2013. Any voltage higher than about 55V could damage the Arduino. The point on the resistor divider network connected to the the Arduino analog pin is equivalent to the input voltage divided by 11, so 55V 11 = 5V. In other words, when measuring 55V, the Arduino analog pin will be at

Arduino Button With No Resistor: It is simple to connect a button to the Arduino. You need the button, some wires, and a resistor. In the setup() function, we set the button pin as a digital input and we activate the internal pull-up resistor using the INPUT_PULLUP macro. …

How to disable internal Arduino ATMEGA pullups on SDA and

We can avoid using an external pull-up or pull-down resistors, simply by using the internal existing pull-up resistor within Arduino. This may make life easier when we use pushbuttons.

Precise voltage measurement with an Arduino microcontroller

If the pin is configured as an INPUT, digitalWrite() will enable (HIGH) or disable (LOW) the internal pullup on the input pin. It is recommended to set the pinMode() to INPUT_PULLUP to enable the internal pull-up resistor. If you do not set the pinMode() to OUTPUT, and connect an LED to a pin, when calling digitalWrite(HIGH), the LED may appear

0 Ways to Destroy An Arduino. Introduction. With a typical internal resistance of only 25 ohms per pin, a dead short to ground can allow as much as 200mA of current to flow, more than enough to destroy the microcontroller pin. On the Ruggeduino a 1k resistor is placed in series with the ATmega328P reset pin. If voltages greater than
