QUESTION

Display data from two json files in react native

Asked 2020-May-17 at 23:55

I have js files Dashboard and Adverts. I managed to get Dashboard to list the information in one json file (advertisers), but when clicking on an advertiser I want it to navigate to a separate page that will display some data (Say title and text) from the second json file (productadverts). I can't get it to work. Below is the code for the Dashboard and next for Adverts. Then the json files

Install Star_Tracker

Bunch of wires and connectors. You should add the four resistors between STEP-GND and DIR-GND pins to avoid a jitter of stepper motors at startup. A typical extender for A4988 has an ENABLE pin, however, we do not need it. Instead, we need a pin for controlling microstepping. That is why you should hardwire the three microstepping pins and you should add a single pin to control them. Search for microstepping resolution truth table of A4988. A cheap IR remote control might have a weak diode. In that case, you won't be able to control the mount from a distant places. So I recommend you to replace the diode with a better one. You also need to tune potentiometers of stepper drivers. Search for How to set output current limit on A4988 stepper driver. This can reduce noise produced by the motors or you can remove problems with skipping of steps. Use the potentiometer connected to the LCD to adjust contrast.
Arduino MEGA2560, unfortunately Arduino Uno cannot be used due to the lack of memory
Power supply or battery, e.g. 12V and around 2.5A (depends on your stepper motors)
2× NEMA 17 stepper motor (forget about 28BYJ!)
2× stepper motor driver like A4988
2× stepper driver extender for A4988 (we will modify this part, so you should consider custom design with 100μF capacitor)
4× 4k7 or 10k resistor (or any other suitable resistor you hold in your hands)
(optionally) Gearboxes for the motors (battery screwdriver is typically much cheaper than profi gearboxes and has some planetary gearboxes inside!)
2× flexible shaft couplers for joing the motors with mount
Real Time Clock, note that DS3231 or more precise clocks are preffered over DS1307
microSD Card module
16×2 LCD (without I2C module)
10k Potentiometer
IR receiver
Remote control, you can use your favourite one you use for TV or you can use any other for makers! This repo settings match with a remote control by Makeblock.
Some kind of transistor, e. g. BC337 and suitable resistor, e. g. 1k ohms
Bunch of wires and connectors
