Hi, Great website and Youtube channel. I am building the DIY 7 servo radio control system, but I need the switch channels 5 & 6 to give a digital 1 or 0 output relative to the switch positions and not to operate servos. Please can you tell me what lines of code I need to change on these channels to do this. Many Thanks

hi, I need to run a 24v 15A dc motor from a 48v 4A solar panel. can you give me a circuit diagram for this purpose.

Drawing bitmap images (.BMP format) on ST7735 TFT display is quite easy because they are uncompressed images unlike JPEG images (.JPG format). This post shows how to draw bitmap images on the ST7735 TFT using Arduino UNO board where the Arduino loads the BMP images from SD card and print the... view more

Working on digital watch that will look like something a combination of analog and digital watch. This project will highlight you about controlling the shift register and how I changed my whole Arduino code into PORT Register control when there was so much lag during printing the numbers on 7-Seg display. I have made a 2D design first on illustrator and then made 7-Seg display my self.. I will upload my project soon.

In this tutorial I'll show you the circuit of a basic wireless charger, the transmitter and receiver. See how to adapt the resonance and transfer power. Then how to regulate the receiver output at 5V so we could charge a smartphone via USB. Hope you'll learn something new. view more

Presento un control PID para posicionar un motor DC y está basado en el algoritmo publicado por Brett Beauregard. Modifiqué el algoritmo original para "suavizar" la respuesta del motor, dándole unas características únicas, entre ellas un posicionamiento al punto designado mucho más sua... view more

tengo 10 años y desde los 8 me a empezado a interesar la robótica soy de Perú y no se mucho sobre el tema , pero igual entre a este foro porque quiero ver sus ideas , la robótica me gusta pero es una de mis muchas pasiones como es la música , la cocina , los juegos de mesa , la programación , etc , pero la robótica esta un poquito mas arriba de todas mis pasiones , de grande quiero estudiar ing. robotica con ing. de sistemas y si alcanza programación
