It will be formatted in a scrolling window that makes it easier to read.Ĭan you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?ĭo you have code that just reads the analog inputs, without any dislplay code, and serial prints them to the monitor?ĭid you write your code in stages and get each stage working before combining them? Digital Input pins : 54 pins (14 PWM output) Analog Input pins : 16 pins. Input Voltage (recommended) : 7-12 volts.

then look down to item #7 about how to post your code. The specification of Arduino Mega 2560 are as follows. Please read the first post in any forum entitled how to use this forum. Temperature = (sensorValue3 * 100.0) / 1023 įor the future please post your code between tags so your code looks like this and is easy to copy to a text editor #define LCD_CS A3 // Chip Select A3 Input_current = (sensorValue2 / 1024.0) * 5000 // Gets you mVĪmps = ((input_current - ACSoffset) / mVperAmp) The board provides 76 digital inputs/outputs (13 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. Tft.setRotation(3) // Need for the Mega, please changed for your choice or rotation initialīattery_voltage = (sensorValue1 / 1024.0) * 5.0 Īctual_batt_volt = (battery_voltage * (R1+R2)) / R2 Īctual_batt_volt = actual_batt_volt - offset_voltage The Arduino GIGA R1 WiFi brings the power of the STM32H7 to the Mega form factor, being the rst Mega board to include onboard Wi-Fi and Bluetooth connectivity. The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment).

Int sensorValue3 = 0 // value read from the pot3 Int sensorValue2 = 0 // value read from the pot2 Int sensorValue1 = 0 // value read from the pot1 a simpler declaration can optionally be used:Īdafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET) Ĭonst int analogInPin0 = A11 // Analog input pin that the potentiometer1 is attached toĬonst int analogInPin2 = A13 // Analog input pin that the potentiometer2 is attached toĬonst int analogInPin4 = A15 // Analog input pin that the potentiometer3 is attached to If using the shield, all control and data lines are fixed, and Assign human-readable names to some common 16-bit color values: #define LCD_RD A0 // LCD Read goes to Analog 0 #define LCD_CD A2 // Command/Data Register Select A2 The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Pls read it and tell how to avoid voltage variations and how to implement in coding. You could write some code that only prints a new value if it differs from the previous value by X It is not unusal to get small variations in readings from an ADC. First, please post your program so we have some idea what the problem is.
