    Vending Machine based on STONE HMI and Arduino

    I was recently conceptualizing a project that required a touch screen display, so I purchased some different brands of LCDs and I wanted to make a touch screen display for a vending machine. Finally, I decided to use STONE 15.1'' TFT LCD and Arduino for a simple simulation. Does anyone have a...

    Special development board

    Hello Currently the Grape-Express Mini development board is on Kickstarter. It's a microcontroller board like the Arduino Mega2560 R3, but this board includes a lot more than just Bluetooth, Wifi, and self-sufficiency. If there is interest, then look on the web page. The goal is not set high but...

    Display with LEDs - What technique to use?

    I am planing to create kind of a display with LEDs. Round or square, the board's expected size could be around 30 x 30 cm. LEDs' position is not expected to change; just the programing of the driver. Number of LEDs expected to be, most probably, around 64, laid in straight lines. Accuracy of...

    I2C display doesn't give an acknowledge

    Hello everyone! I've got a NHD-C160100DiZ-FSW-FBW display and a Simcom sim5360 module. The display is connected correctly - that is for sure. I tried to get connected using a datasheet example (using Lua language), but the display doesn't get ACK-bit - the SDA line is staying HIGH. Here is a...

    7 segment 3 digit Temp Display

    Hello again, I'm working on a project to display the temperature of a thermocouple (I ordered the amplifier already) on a 3 digit 7 segment display, but I've never done it and I cant make much sense of what there is on the internet. Ideally I would like to use an arduino mini or nano (I...

    MCU voltage mis-match to LCD

    Hello, Regarding Renesas part number R5F100LEAFB#V0: I have its data lines and control lines tied to an LCD (operating at 5V). The R5F100LEAFB#V0 has EVDD at 3.3 V. Will the R5F100LEAFB#V0 be damaged due to the voltage mis-match to the LCD (3.3V vs. 5V)? Thanks, Calvin
