This article provides several low component count circuits you can experiment with, plus many interesting technical points to consider.
At this point, we have a Nextion touch screen programmer and an assembled and programmed PIC ignition timing controller. To wrap it up, we’ll install it on my son’s Manco go-kart to see how she runs.
Last time, we designed the printed circuit board and other hardware for our controller. This round, we’ll design the software.
Previously, we discovered how easy it is to add objects to the Nextion display, dress them up, and communicate with a PIC MCU. In this installment, we build the Small Engine Ignition Timing Controller and Programmer hardware.
Part 1 of this mini-series was also Nextion Part 3 (last Issue), where we started designing a programmer for our Small Engine Ignition Timing Controller. So, consider this installment really Nextion Part 4. Now, we build the Tune and DataLog Pages.
You have found or designed a circuit, and it’s time to build a permanent version of it. You could design and order (or make) a printed circuit board, but that will cost money and/or time. It also makes changes and corrections difficult. The obvious alternative: Implement the circuit on one or several prototyping boards. So, how do you go about building on a protoboard? I’ll describe a sequence of steps here.
Back in Part 1 of this series, we designed a simple Nextion display screen and got it to do stuff. However, the look was rather droll. In this installment, we’ll use the Nextion in a special application (building a small engine ignition timing controller) and make the screen sizzle.
