TX node:RX node:Basic idea:Arduino on the TX node reads analog joysticks which have value between 0-1023 (10 bits) and reads the switches.nRF transmits data to the reciever. Total payload of 5 bytes.5 bytes are10 bits of throttle- reading from joystick,...
Measuring the temperature of a given environment is very important, because, through this parameter, it is possible to control various processes such as industrial ones, those related to incubators, processes for refrigerating small devices or large...
In order to power the vehicle, the required voltage can be obtained from the Photo Voltaic Module. But it is expensive and a large number of panels are required to produce this voltage. So to make economic and usable in a vehicle, power converters are...

Hello Here is the story of building a 4m x 1.60 m led panel 123 *48 leds I started first with smaller boards 20*15 then 20*30 just to have an idea of what it possible. And use couple of controllers (Arduino uno, due, mini, pro, esp8266,esp32) it...
At the beginning of the new year, robot/Smart Car hobbyists and students (like all of you) about engineering, science and technology are busy with preparing for the robot competitions now. It's the great time to show the world your imagination and potential...
-- VGA display using a bus_master as a GPU for the HPS. Display from SDRAM. A simple GPU was written that only writes rectangles. It takes corners (x1,y1 and x2,y2) and colors from the HPS in SRAM scratchpad memory and displays them into SDRAM-buffered...
