This takes the temp and relative humidity from a dht11 and converts the information to a "feels like temp". the humidity , temp and "feels like temp" are displayed on an lcd (i2c). the "feels like temp" is also mapped to a nrgb led. the led turns blue when cold, green when comfortable and red when hot.

LM75A - Digital temperature sensor

A crash course tutorial baked as a project

Some utilities (counters and pulse multiplexers) for menu based aplications. Also patches for the 20 x 4 i2c LCD display (now with cursor indicator opotion); the HP50827340 1 digit hexadecimal display and the Iduino Joystick Shield V1.A. Also there is a pulse decoder for rotary encoders and a patch to format an integer in n number of spaces, right justified.

Delay the transmission of the incoming "true" value

Time-of-Flight (ToF) sensor. Arduino library for the ST VL53L0X sensor (https://www.st.com/en/imaging-and-photonics-solutions/vl53l0x.html). Wraps the Pololu VL43L0X library for Arduino (https://github.com/pololu/vl53l0x-arduino).

This is a simple library for controlling the L298N Stepper Motor Driver Controller Board Dual H Bridge Module. This module is readly available on amazon and is easy to use for single/dual motor control or as a stepper motor driver.

http://osoyoo.com/2017/07/24/arduino-lesson-obstacle-avoidance-sensor/ This object inverts the return to show True when the sensor detects an obstacle. The Enable Pin is onlused on the 4 Pin version of this sensor and is used to turn the pin on and off.

Read´s the temperature from LM75A i2c temperatursensor with 11 bit (0.125°C) resolution 0.30.0 ready

Pulse-oximeter. Arduino library for the MAX30102 (https://datasheets.maximintegrated.com/en/ds/MAX30102.pdf). Wraps the SparkFun MAX3010x sensor library (https://github.com/sparkfun/SparkFun_MAX3010x_Sensor_Library) written by Nathan Seidle and Peter Jansen. This XOD library is a work in progress - a node for measuring oxygen saturation will be added soon.
