RC Transmitter and Receiver | YK04 Explained | DIY robot car

Making DIY robot car with RC receiver and transmitter YK04

In this tutorial, we will learn about YK04 receiver and its transmitter. We will also create a robotic car with 2 wheels to understand how RC receiver works.


Detailed video below


Parts Needed

1. RC transmitter and receiver pair
2. Jumper cables
3. L298N motor driver
4. BO motors with wheels
5. Mounting brackets, chassis and screws


Circuit


Wire connections

RC receiver           L298N 
     5V                        5V
    Gnd                     Gnd
     D0                        IN1
     D1                        IN2
     D2                        IN3
     D3                        IN4
                                 
Connect 12V power supply to 12v +pin and Gnd to Gnd.
Connect BO motor terminals to output terminals.

Assembly

Lets start with BO motor mounting. 



Post brackets are fixed



Post this lets mount this on to chassis. 


Troubleshooting

1. Please verify channel associated with your receiver an change connections to L298N inputs.
2. Check motor terminals connected to L289N they may require changes.
3. Antenna is broken on reciever.
4. Open transmitter antenna if range is not sufficient
5. Consider adding powerful antenna using copper wire coiled to increase range.
6. Stability issues with chassis. Considering mounting tight and replace wheels which are wobbling.

Microphone Sound Sensor explained | HW-484 | Interfacing with ESP 8266

Image
 Microphone Sound Sensor In this tutorial, we will learn about microphone sound sensor which is used to measure sound intensity. The sensor takes in ambient sound and provides a voltage corresponding to intensity in both digital and analog outputs. We will see both cases of outputs. Case 1 : Using Digital Output In this we will try to lit an Led if the voltage output is above a threshold. Parts Needed 1. ESP 8266 NodeMCU 2. 330 Ohms resistor 4. HW 484 Sensor 5. Power supply 3.3v/5v 6. Led  7. Jumper wires and bread board Connections Power supply 3.3V - HW484 + Power supply Gnd - HW484 G NodeMCU D4 - HW484 D0 NodeMCU D2 - 330 Ohms Resistor - Led CODE boolean soundValue = 0 ; void setup ( ) {   pinMode ( D2 , OUTPUT ) ;   pinMode ( D4 , INPUT ) ;   Serial . begin ( 115200 ) ; } void loop ( ) {   soundValue = digitalRead ( D4 ) ;   Serial . println ( soundValue ) ;   if ( soundValue == HIGH ) {     di...

Using ESP 01 in Access Point (AP) mode to control ESP relay switch | ESP wifi tutorial | Part - 1

Image
Control ESP relay switch using wifi access point on ESP 01 In the last tutorial , we have seen how to control relay using ESP 01 as micro controller. In this tutorial, i will attempt to introduce ESP relay switch designed to work seamlessly with ESP 01.  we will also control the relay in built wifi capability of ESP 01. We will attempt to use Access Point (AP) Mode which allows devices like mobile, laptop and other esps to connect to wifi network created by esp. This mode can be used to create a local network to control and communicate between master and slave nodes. We will setup a web server on ESP 01, use it to change relay state on a android mobile. ESP Relay Switch This is a relay switch with inbuilt slot for ESP 01. It has 5v and GND terminal to power relay and ESP 01. It has NC, COM and NO terminal to collect output of the relay. ESP relay switch front and back view. Hardware requirements 1. ESP relay switch. 2. Multi output voltage converter power module 3. Led Strip connec...
