    I have a simple circuit that is a battery operated rgb color switcher that runs on a PIC10F202; When the button is pressed, the single RGB LED changes to the next color in the sequence. When the battery is installed, the unit is on, and when the battery is removed the unit is off. What I need is to have the code modified so that the uController behaves in the following manner: 1 Unit is off with battery installed 2 Button is pressed once 3 Unit turns on with last selected color illuminated 4 Successive button presses will cycle to the next color in the sequence (R->G->B->Y-C->M for example) 5 Unit will stay illuminated in the current selected color until, 6 Long press (2 seconds) will shut the unit off and save the last selected color in memory 7 Operation repeats as above ...

    Hello everybody, me and my six person team are developing a real-life hardware payment portal which runs with crypto currency payment like IOTA, BTC and ETH. The payment portal has a display introducing the customer. After successfull payment the integrated switch turns on any service, e.g. washing machine (pay for action), car wash (pay for action), car charging device (pay for energy). There are endless use cases. See benefits in the appendix. For this job I would like to get a print ready DIN A4 brochure 2 or 3 folded, both sides illustrated. The hand-over data should be TIF, PDF and native format. After this first project, if both sides of partnership are confident with each other, I would like to continue with designing a proper logo, website and possibly a smartphone application...

    I have 2 PLC,s communicating with wireless Modbus RS 485. Slave requires minimal code measuring up to 30 PPS, battery voltage a latching relay and possible count reset command. My intention is to eliminate the Slave PLC. I'm looking for someone who can help me with: (1) I have programs written into 2 PLC,s 1 Master and 1 Slave they are linked via RS 485. (2) They communicate through 2 RS485 wireless transceiver,s The Slave PLC has got a very simple program in it . My task is to move the program in the Slave PLC into a microcontroller. I'm presently using an Arduino UNO for the task I've got the majority of the coding done. In closing, I need someone who has SPECIFIC knowledge in IDEC PLC,s and Arduino microcontrollers.
