Need to understand :o how to display PRND one letter at a time on a ssd1306 .96" OLED display. Based on analog inputs. Like A0 low (ground) input display shows P A1 low input displays R etc. I will use micro switches for the low inputs connected to automatic trans shift lever. Arduino R3 board. Where can I find a good example I can modify etc?
Nothing useful. Been looking all morning for an example to make gear position indicator. Not a bike but for a truck.
I want to make a gear position indicator for my old Chevy truck. I have some OLED displays and a spare Arduino R3. As the shift lever moves to each gear position it will hit in sequence each micro switch. One for each gear like Park-Reverse etc. I want to display P,R,N,D,2,1 as each switch is tripped so I know what gear the transmission is in. I am new to this but not to mechanical or electrical 35 year auto tech. If I am in the wrong place kindly suggest the right place. Don't want to be given a sketch but want to use one close enough to learn from. Link to the right spot?
Thanks for your reply's so far
Arduino R3 .96" OLED with i2C I want to display P R N D on OLED when a micro switch provides a ground as each gear position is hit. Use A0-A3 as low input for each position. I will use one micro switch for each position 4 total. A sample sketch on how to use the inputs to display on a OLED or link to the best place to ask this question. I have samples for OLED like to display characters, symbols, images etc but nothing on how to make it display what I want using analog inputs.
Thank you!
Try the "Gigs and Collaborations" section of this forum. Have a think first about how much you are willing to pay, and how many hours of effort that buys at minimum wage.
Thanks but I wanted to try myself. Just need a little help getting started.

Well, I'm glad to hear that, but it isn't how your post sounded to me, I have to say. Try reading it back to yourself.
Post your schematics and the code you have tried so far, even of they might be way off the mark. At least it demonstrates your willingness to learn and try stuff out. Read the forum sticky post, it will tell you how to post those things correctly.

Have you managed to get any text on the display ?
Your statement is correct. Sounds like you just need it statements checking to see which switch is made and setting a char variable with whatever letter you want. If the letter changes then clear the screen and print it. Sorry if I have been short or confused sounding. Dr orders to find a stimulating new hobby.
I have been looking around so far Here is what I have decided: Use the digital I/O pins for a total of 6 separate inputs(one each gear position). They can be a ground(low) or some fixed resistance value. New char or characters displayed depending on which pin has an input. I2C-.96 OLED for one char or a I2C-1602 LCD shield for gear position words. I have been looking at some examples. When I have a rough-crude sketch to show I will post it. Unless I can find a close example to fiddle with.
Thanks again
