Solution to create home network via nrf24 and arduino.
Plus LEDcontrol, DHT11(temperature sensor), IR control, button control, IR motion Sensor.
Arduino-run board that performs MPPT functionality on a power input to maximize power production for solar panels, wind generators and TEGs, and then regulates to 18V.
Input: 1-120VDC @ up to about 100W (10A max current regardless of voltage)
Output: 18VDC @ up to 10A (max 180W)
this is a very smal SMD print for the 23LC1024.
the 23LC1024 a 1024 kb SRAM chip.
i will try to make it work with arduino but succes is not guaranteed.
1 X 0805 100nF capacitor
3 X 0805 10k resistor
1 X 23LC1024 (SMD version)
(1 X 6 pin header male or female. whatever you want)
Repurposing an old laptop power supply (18vdc) and dozens (actually - hundreds...) of white LEDs from old solar powered Christmas lights, to build an illuminated 'Merry Christmas' sign (a la Big Clive's Arcade sign).
The LEDs are made into strings of 5, each with a current limiting resistor, and a switching transistor to control the string. The transistors are switched from the outputs of multip...
## Water Sensor to Arduino ##
![enter image description here]
When a drop of water onto the sensor, digital output port raindrop sensor module can output low, the analog output can change the output voltage based on the number of raindrops, the more raindrops, the lower voltage. When the sensor detects water, the digital output port high, the analog output voltage of the power supply voltage...
## 360° Rotary encoder for arduino ##
360° Rotary encoder (rotary encoder) can be converted into a rotational position or rotation amount signal (analog or digital), through a certain way (mechanical, optical, magnetic, etc.), that the axis of rotation, and send a signal to inform us. Can be divided into absolute type (absolute) and incremental (incremental) or called a relative type (relativ...
