I'm sorry to inform that the schematic doesn't match the PCB. MOSFET is an PHP55N03LT (it seems to work) the 8-pin IC is a AS358 (dual opamp), there's not Shotky diode, ZD801 is a 1.5v Zener

Thanks, i'll try!

I'll share an example by Dejan from HowToMechatrinics, if you need more help understanding the script, please let me know: /* * How I2C Communication Protocol Works - Arduino I2C Tutorial */ #include <Wire.h> int ADXLAddress = 0x53; // Device address in which is also included the 8th bit for selecting the mode, read in this case. #define X_Axis_Register_DATAX0 0x32 // Hexadecima address for the DATAX0 internal register. #define X_Axis_Register_DATAX1 0x33 // Hexadecima address for the DATAX1 internal register. #define Power_Register 0x2D // Power Control Register int X0,X1,X_out; void setup() { Wire.begin(); // Initiate the Wire library Serial.begin(9600); delay(100); // Enable measurement Wire.beginTransmission(ADXLAddress); Wire.write(Power_Register); // Bit D3 High for measuring enable (0000 1000) Wire.write(8); Wire.endTransmission(); } void loop() { Wire.beginTransmission(ADXLAddress); // Begin transmission to the Sensor //Ask the particular registers for data Wire.write(X_Axis_Register_DATAX0); Wire.write(X_Axis_Register_DATAX1); Wire.endTransmission(); // Ends the transmission and transmits the data from the two registers Wire.requestFrom(ADXLAddress,2); // Request the transmitted two bytes from the two registers if(Wire.available()<=2) { // X0 = Wire.read(); // Reads the data from the register X1 = Wire.read(); } Serial.print("X0= "); Serial.print(X0); Serial.print(" X1= "); Serial.println(X1); } Regards from Argentina.

Hi! have you tried using a Raspberry with octoprint installed on it as Gcode server? is a linux debian based OS used to control 3d printers via web server. you can install the arduino+raspberry on a faraday shield case with a good EMI filter. If you're interested on it, please let me know and i'll share more info... Regards from Argentina. Julio.

Já testei a fonte de alimentação conectada na placa principal, sem os leds ligados, ainda não funciona... Aqui você tem as fotos da placa principal (vista superior e inferior): I've tested the power suply conected to the main board, without the leds conected, still not working... Here you have the photos of the main board (top and bottom view):

Hey there, how's going? If you need to control the time with more accuracy i'll recomend to use a microcontroller with a RTC (DS1302 ot DS1307 are I2C, there're arduino modules based on them). So you can program the time like a clock and do whatever you need. I'll also recomend you to use an Arduino Nano (based on Atmega328P) so you forget about the electronics... Regards from Argentina. Julio.

Ei! como está indo? Desculpe meu português, minha língua materna é o espanhol, e me defendo bem com o inglês. Sinta-se à vontade para responder no idioma de sua preferência. Preciso de ajuda com minha placa principal Philips 223v5... O PS cai quando conecto a placa principal. Se eu deixá-lo desconectado, o PS fornece 15v em sua saída. A placa é 715G7910-M0B-000-004F. Não há elementos queimados visíveis nem curtos-circuitos em componentes conhecidos. ¡Hola! ¿cómo va? Necesito ayuda con mi placa principal Philips 223v5... La fuente se cae cuando conecto la placa principal. Si la dejo desconectada, la fuente proporciona 15v en su salida. La placa en cuestión es la 715G7910-M0B-000-004F. No hay elementos quemados a simple vista ni cortocircuitos en componentes conocidos. Hey there! how it's going? I need some help with my Philips 223v5 main board... The PS goes down when I plug in the main borad. If i left it disconected, the PS provides 15v on its output. The board is 715G7910-M0B-000-004F. There are no visible burnt elements nor short circuits in known components.

Olá, eu sou o Júlio. Engenheiro eletrônico da Argentina, estou aqui para ajudar no que puder. Saudações e eu os leio em breve!
